Short Description

Building dimensions using the Slowly changing dimension wizard in SSIS is simple and quick. However its performance and flexibility is questionable. Even further, when trying to perform incremental loads of your Dimensions using the aforementioned approach or a custom approach prior to Change Data Captured (CDC) offered certain challenges. In this session Patrick will show you how to utilize CDC and SSIS to incrementally load Type I and Type II dimensions ;using features that are all native to SQL Server 2008.

Enable Macros in Access 2007


  • We have a couple of access programs that we use for data conversions. These programs convert the csv files that are generated from our CRM to a fixed file format that is then uploaded to interface with other government institutions.
    With the introduction of OFfice 2007 there is this extra step that the users were required to do to enable macros manually every time they use these programs.
    I thought this manual should not be there for the users so I set out to look at all the options available to automate this step.
    HEre are the results.

  • Open the access file -- click on the office button at the top and click on Access Options
  • From the menu that appears choose the Trust Centre and click on the Trust Centre Settings.
  • From the menu that appears choose Macro settings and Enable (the fourth option) and click ok.
  • Next time when you open the porgram the annoying notification where there is a tendency to forget to enable will disappear.

39 videos on Microsoft BI Tools

I stumbled across this site today that contains very useful videos on Microsoft BI tools.

There are 39 videos of which I have listed the top five from thier site here.
  • The first video is a twelve minute introduction entitled "What is Business Intelligence?" This video covers what is meant by terms such as data warehousing and business intelligence and why companies undertake such projects.
  • The second video is a 34 minute overview of how a single data warehouse can be used to deliver business value to a wide variety of users through scorecards, dashboards, reports, analytic applications, and custom applications.
  • The third video discusses the process of data warehousing, from the initial problem definition through the creation of the cubes and delivery of the data. This video runs 19.5 minutes.
  • The fourth video is "Why Business Intelligence Projects Fail (and what you can do about it)." This covers some of the primary reasons that BI projects fail along with tips for addressing the problems. This video is 32.5 minutes in length.
  • The fifth video is "Introduction to Business Intelligence Development Studio" and covers the primary tool used to create data warehouses. This is the environment for creating SSIS packages, SSAS cubes, and SSRS reports. This video runs 15.5 minutes.

    So go ahead and register and enjoy the videos

Show/Hide Office Ribbons

Yesterday I was in a presentation and because we wanted to see most of the screen, there was a requirement to hide the top ribbon see the image below.




I suggested to double click on the menu item to hide the ribbon. That is, double click either on Home, Insert, Pge Layout etc.

Someone in the room suggested a keyboard shortcut Ctrl+F1. That worked too.
Also keep in mind that this works across all Office 2007 and 2010 applications including Excel, Powerpoint, Access, Outlook etc.

I thought of sharing this here so that in case you have a similar requirement you could use it.

New Path to Microsoft Certified Master (SQL Server 2008)

I came across an interesting blog link yesterday by Joseph Sack which outlines the new path to get certified for Microsoft Certified Master.

The current MCM program requires you to take three written exams and a six hour lab exam which would cost around 15,000 USD.

The new MCM program requires you to take a knowledge exam and a lab exam which would cost $2500.

In his blog, Joseph says -- "It’s our goal to reach the SQL Server experts worldwide who may be qualified to achieve MCM certification, but who’ve run up against the previous barriers of time, cost and location. By reducing or removing these barriers, while keeping the integrity and value of the certification, we expect to grow the community of SQL Server MCMs and increase its visibility and awareness of its value."

I hope this helps all the people who are trying to get certified as MCM.

List of users and their permissions

Yesterday I wanted to know which users have what permissions to a database. So I started querying the two tables related to it.
select * from sys.database_permissionsselect * from sys.database_principals
I came up with the following script to suit my needs.

select USER_NAME(perm.grantee_principal_id) AS user_name, princ.principal_id, princ.type_desc AS principal_type_desc,
perm.class_desc,
OBJECT_NAME(perm.major_id) AS object_name,
perm.permission_name, perm.state_desc AS permission_state_desc
from sys.database_permissions perm
inner JOIN sys.database_principals princ
on perm.grantee_principal_id = princ.principal_id

There may be numerous other ways to do this.

Grant and Revoke Privileges

Today I have accidentally given access to a user using the grant option by issuing the Grant sql command.

GRANT VIEW ANY DATABASE TO username;

GO

I have immediately realised that I didn't want to give access to that user and hence I had to revoke the permissions.

REVOKE VIEW ANY DATABASE From username;

Thought I would document this here so that any one doing the same would benefit from this.

Also there is a With Grant option that you can use while using Grant option.

The main difference between Grant and With Grant option is that --
If only GRANT is used, the user cannot grant the same permission to other users.

IT Systems Viability

We have been using a CRM application heavily customised to fulfil our needs as a Training Management System for the last 10 years. Now the applications vendor has changed the technology behind this application to be in line with the latest technology and released a brand new application.

This means that we have to rethink the capability of our heavily customised system in future as it is not a case of simply upgrading to the new application. It is basically a rebuild of all the functionality we have developed over the last 10 years.

This situation has made me think of the question – How long should IT systems be viable? Of course there is no right or wrong answers to this question as it depends entirely on the business requirements and the functionality available at the time in the IT systems being used.

The bottom line is our expectations keep on changing as per the business and most systems cannot keep pace with these changes. Hence there is a need to choose new systems.
The life span of Systems has a big impact on the business costs. You can reduce the cost of replacement if the systems are utilised longer. We are thinking of utilising our CRM application for a bit longer as the functionality released by the new version of the application is no where near the functionality that our current system provides. WE just have to make sure that we do not roll out new versions of other applications like office and operating systems without proper testing for compatibility.

What are your views of IT systems viability?

The hardly used stuff function

My share of todays learning at sql share is the unusual stuff function. I have not heard of this function before and here are my learnings from the video by Andy Warren.
  • Stuff function inserts a string into a string at a specified position. It feels a bit like REPLACE (and you can certainly use it that way), but it's really designed to do something different - push x characters into a string based on an index and length.
  • Andy was surprised to realize it was the only string function he had never used to solve a problem.
  • If you try to use the stuff function to insert a null at a certain position of the string to replace a few characters, it does not error but it just returns the remaining characters after removing the number of characters you have specified.
  • If you try to use the stuff function that has null in its string, no matter what you try to replace it with it returns null

To learn more watch the video by Andy Warren.

Quotename Function in SQL

I have learned something very basic today from the sql share video today. It is about the Quotename TSQL function. This function I think is hardly used and hence some of the developers may not be aware of this. Hence I thought I will put my learning about this function here.
  • Quotename function returns the string along with the delimiters added in the function.
  • This function can be used if you are using the delimiters repeatedly.
  • If you are using delimiters on an ad-hoc basis you can just use something like select "-" +@variable +"-"
  • One requirement for using this funciton is that the string cannot be more than 128 characters long as depicted in Andy's video


Thanks to Andy Warren who explains the various ways of using the quotename function in this video.

Copy Paste problem in excel 2007

Today one of my colleagues was working in excel. He had a dataset that in one sheet which was filtered. He wanted to copy those records that were filtered into a new worksheet. But when he copied and pasted the cells into another sheet the cells that were pasted contained all the rows. What he wanted to copy was only the filtered rows. This becomes a problem sometimes in Excel 2007

To overcome his paste problem I have suggested the following steps

Go to the Editing group in the Home tab
Click on the "Find and Select" button
Click on the "Go to Special" from the list
And click on "Visible cells only " radio button and click ok

Now you can copy and paste only filtered rows in excel.

Another quick turn around is open the workbook in another computer where the filtered cells copy paste works and do the first copy and paste and close the worksheet.
Now if you open the spreadsheet on the first computer the filtered cells copy and paste works !

Improvements on the Learning feature of sql share

Andy Warren of SQL Share is bent upon motivating learning to all the sql share subscribers. Here are some of the new features he has included in his recent emails.

  • The first feature he launched was to show the learning goal in minutes per month. Now we can set an annual goal and monitor our learning.
  • The other new feature is you can log in your own learning which is outside of sql share so that all learning can be monitored which is a really cool feature which helps the learner focussed on all the learning he is undertaking.
  • All these can be monitored from the Profile page.

    Thanks to Andy for providing these tools which helps all of us in our learning.

Using Registered Servers in Managment Studio By Andy Warren

Today's featured video on SQLshare / Jumpstart TV is Using Registered Servers in Managment Studio By Andy Warren . Until I saw this video I didnot know about the Registered servers view in sql server 2005 even though I have been using the Management studio for the past 3 years.

Here are my learnings of today.

  • Ctrl+Alt+G is the shortcut for getting in to the registered servers pane. Alternatively click on the -- View menu -- Registered servers
  • From the registered servers pane you create a server group by right clicking on the database engine and creating a new server group.
  • Once a group is created you can also create a registered server instance by right clicking on the server group and creating a new server registration
  • You can rename the server from the Register server name
  • By double clicking on the registered server instance you will be taken to the object explorer which I am familiar with.
  • Most important thing is the settings that you have on your local machine are not reflected on the server and also it is not going to change anything about the server, it is not going to change how we connect to it or how our users see it.
  • Setting custom colour is a very useful new feature (available only in sql server 2008) discussed by Andy in this video. This can be used to differentiate the test servers with the production servers.
  • You can export registered server inforamtion to a file by right clicking on the server instance and choosing export. This feature is very useful when you are moving machines.
    The option "Do not include user names and passwords in the export file" is also very useful if you are giving the export file to a new DBA or another user.

    Thanks to Andy Warren for helping me learn all this within 4 min. 50 secs. If you are interested in viewing this video please click here

When my joystick started giving in...........

The other day I had about 20 excel workbooks to work with in a single day to complete some outstanding work in a tight timeframe. In each one of the excel workbook I was working on, there were about 20-25 worksheets. I use a joystick instead of normal mouse, and we didn't have any spare joysticks. My joystick thought that I have had enough of this and started giving in to my moves. I didn't want to increase my RSI by uisng a normal mouse. Instead I thought I will use some excel key board short cuts to work in these excel files.

Here are the shortcuts that I thought will come handy to everyone.

  • CTRL + PgUp -- To switch to the right hand side of the sheets
  • CTRL + PgDn -- To switch to the left hand side of the sheets
  • F4 -- To repeat last action in Excel (This works only in Excel, I wish it worked in word as well!)
  • CTRL + --> -- To move to the last populated cell on the right hand side
  • CTRL + <-- -- To move to the last populated cell on the left hand side
  • CTRL + down arrow -- To move to the last populated cell in the downward direction
  • CTRL + --> -- To move to the last populated cell in the upward direction.
  • If you hold down the SHIFT key as well for the above four commands the cells are selected.
  • CTRL + Spacebar -- To select an entire column in a worksheet
  • SHIFT+ Spacebar -- To select an entire row in a worksheet

All the above shortcuts helped me in doing my job quickly that day in spite of having a problem with my joystick.

String Handling Functions - Part 1 By Andy Warren

In this video, within 6 min. 29 secs Andy not only shows the usage of Lower, upper, left, right, ltrim and ltrim functions but also displays a few what if scenarios which we may otherwise not think about if we just go by the book.

Here are my learnings:
  • upper and lower functions does not return an error when used with null data.
  • The second argument for left and right functions should be a positive value and cannot be a negative value.
  • If a negative value is used the select statement errors out.
  • If a zero is used as the second argument it does not return an error but it just returns a blank row.
  • There is no trim functions. If you need a trim function in sql then combine the ltrim and rtrim functions to get the desired result. Eg: rtrim(ltrim(@test))

Another interesting feature in SQL Share / Jump Start TV

I noticed another interesting and innovative feature in the SQL share email today. The email features "Your Scorecard". A view of it below.










This scorecard tells me that I have done 35 minutes of learning and my goal should be 120 minutes per month.
I think this is a great feature to motivate you and monitor yourself of how much you are learning. If you can set yourself a goal of 120 minutes of learning per month that should be really good for your career development.

So if you are not yet subscribed please do so from the sql share login link

Delivering KPIs with Analysis Services -- 24HOP recording by Peter Myers

Today I had the chance to view the 24HOP session recording "Delivering KPIs with Analysis Services by Peter Myers"

Here are my learnings.

What are KPIs?
  • KPI -- Key Performance Indicators are quantifiable measures comparing business performance to goals
  • KPIs are aligned with corporate strategy and objectives.
  • KPIs are designed to drive desired behavours
  • KPIs presents a measure of overall organisational health when combined into a collection for a business scorecard


KPI data requirements


  • A KPI should have at least an actual and a target value
  • Ideally corporate data systems will deliver both values
  • Actuals are typically retrieved from operational databases
  • Targets can be retrieved from planing systems
  • Sometimes the target values can be stored in supplementary data stores or can have fixed traget values.


The Demos included covered the following aspects.

Preparing the cube to store target values
Seeding arget values based on historical actual values using simple factor, data mining (time series)
Contributing target values using Excel 2010

Using Checkpoints in SSIS By Brian Knight

Here is the link of today SQL Share / Jumpstart TV video. Prior to viewing this video I had no knowledge of what checkpoints are.... here are my learnings out of this video.
What are checkpoints?

Checkpoints are setup to ensure that you can run the package from the failure point. These checkpoints are particularly useful when packages take a very long time to run.

When the package fails -- the problem can be fixed and the package is restarted. When checkpoints are used when the package is restarted the package restarts from the point where the package has failed. This will save alot of time for the DBAs and Developers.

Here is the process for creating simple check points by Brian

Step 1 Configuring the packageIn the package properties pane give a name to the property -- checkpointfilename The next property to be set is the CheckPointUsage -- Choose the If Exists option.The next property to be set is the SaveCheckPoints -- set it True
Step 2 Task propertiesChoose the task in the control flow and under the Execution group of the task properties falipackageonfailure -- TrueSet this property to True for all the tasks in the package.
This is the process of creating the checkpoints in the control flow layer in SSIS packages.

Converting Crystal reports to SSRS

We have a number of crystal reports that we use and in the near future we need to convert them into SSRS reports. I have done some research on the internet and here are my findings.

The first one is a manual migration process suggested by Microsoft -- Link here I cannot imagine converting almost a 1000 reports to SSRS reports. I cannot imagine myself taking up this process.

The second one which came up in my search was the rpt to rdl website run by Jeff-Net. They have two types of conversion service as they call it. Jump Start conversion service and Full Conversion service. They say that it is a service and they donot have a product.

The third one was a product called Crystal Converter by KTL Solutions You can download a Demo version of this product and try out for yourself.

The fourth one is an online service called Crystal Migrator where you can give your email address and upload a single crystal report at a time. The converted report will be emailed to you.

This is just a list of what I have found worthy of note. I still haven't tried any of these yet. Will post my feedback once I try them.

If I have missed out anything please let me know so that I can update my list.

Notepad Basics

The other day my colleague showed me the menu item "View -- Status Bar" in the notepad. I always used to see a grayed out option of the status bar in the past. But this time I could choose the option to actually show the status bar in the notepad. This status bar shows you the curent postion of the cursor in terms of line and character position.

I was puzzled at this and did some research and found that if you enable the wordwrap feature the status bar option is grayed out. If you disbale the wordwrap feature then the status bar option is enabled.

I thought this would be useful particularly when a code page needs to be (is) opened in notepad.

Introduction to the CASE Expression By Andy Warren

I have used case statements before several times but there were some new learnings from the SQL Share video of Andy Warren

Here are my learnings of the case statement summarised:

People often get confused whether to use if else statements or case statements in T-SQL. According to Andy, only case statements can be used in T-SQL statements. If else statements cannot be used in select statements because if else statements can be used in control flow.
Following are some of the situations and syntax that can be used with case statements. The most important is included in the last syntax (Syntax 5)

Syntax 1:
case columnname when 'exisitng value1' then 'new value1'when 'exisitng value2' then 'new value2'end as aliascolumnname
The drawback with the above syntax is when the conditions of the when statement is not matched the result returned is null in the column.

Syntax 2:
case columnname when 'exisitng value1' then 'new value1'when 'exisitng value2' then 'new value2'else columnameend as aliascolumnname
When the else condition is used the drawback in Syntax1 is fixed.

Syntax 3:
If you want to use case statement for multiple columns the syntax is as follows;
case when column1='exisitng value' then 'new value'when column2='exisitng value' then 'new value'else column1end as aliascolumnname
Notice that there is no column name after the case in the above statement.

Syntax 4:
Nested case statementswhen formatted looks better and you can understand better
case when columnname1 = 'exisitng value' then case when clumnname2 = 'exisitng value1' then 'new value' else columnname1 end else columnname1end as aliascolumnname
The above can also be written in one case statement doing two tests.

Syntax 5 Last but not the least (Very important learning of the day):
You can use case in the order by clause
select columnname from table name order by case when columnname = 'value1' then 0 else 1 end, columnname.

Aggregrate Queries in SQL Server T-SQL for Beginners By Kathi Kellenberger

My learnings from the sql share video

  • I knew that we cannot use where clause with aggregate functions but I didn't know the reason. The reason is the where clause is executed before the aggregate functions are applied and hence cannot use the where clause with.
  • Count(*) and count(columnname) may yield different results. This is because Count(*) does not ignore null values and count(columnname) ignores or does not count null values.
    When you do aggregation using the AVG function using the isnull function is recommended. Use of isnull function to substitute the null value of the column will give you the correct answer. eg: AVg(IsNull(columnname,0)
  • Always remember to supply an alias for each aggregated function
  • You can use other expression in the aggregate functions instead of just the column names. eg: sum(1) as "sum of ones"
  • When you use a group by clause, make sure select items are exactly same as group by clause, otherwise you might get incorrect results.

SQL Share a very useful video resource -- some positive changes that are helpful

For those of you who don't know about SQL Share here is a snippet from thei About Us page.

SQLShare is a division of Fourdeuce Inc, an Orlando, FL based company that also owns End to End Training, a well known provider of technical training. Fourdeuce is owned by Andy Warren, Brian Knight, and Steve Jones.

I have been getting daily emails from SQL Share since my subscription in April 2010. I used to watch some of the videos. These are small videos that cover various aspects of SQL SERVER by various authors. This is a very good resource for beginners and sometimes helps professionals as well. Everybody will learn something from here. There is no doubt about it.

But getting the email today made a difference compelling me to watch it as soon as I saw the email.

The reason for it is below. Have a look at the image below.



I just couldn't click on "Watch it Later" because I wanted to see because it is written in bold writing clearly that it is going to take only 3 min.

If you don't click on the link after seeing the "Learn Something today in 3 min. 46 secs" which is a minute fraction of 24 hrs in a day then I must say that you are not commited to learning. I looked at the topic and thought "Let me see what I will learn in this which I do day in and day out" But I did learn two points which I have posted in my previous blog.

Andy in his email said that he is experimenting this week. I think this little change will influence a lot of peopl in their learning goals and also credit the author of each featured video who take lot of pains recording it to be useful for the community.

Thanks to Andy who is doing a good job of sending these innovative emails.

Another very important change that was done is when you finished watching the video automatically two multiple choice questions come up to test whether you were really concentrating on the video which I found really useful.

Added to this there is a link "challenge your friend" which I quite like that we can send to colleagues for them to answer if they can.

Using Login Auditing in SQL SERVER by Brian Kelly

Today featured video in SQL Share was Brian Kelly's "Using Login Auditing in SQL SERVER". I watched this 3 min. video and learnt the following.

I know that we can view sql server error logs. I monitor them on a daily basis but I didnt know that the login audit requires a setup that is a bit similar to the normal windows event log set up. This can be set up when you right click on the sql server connection in the management studio and choose properties and then choose Security. There is n option to choose Failed logins only, Successful logins only and both failed and successful logins and of course the none option aswell.

These login auditing will not only appear in the sql server error logs but in the windows event logs as well.

The best part that we are getting as part of watching the sql share videos is testing the knowledge we have acquired immediately after the video finishes which I think is very innovative.

What is Sargability?

I planned to attend Rob Farley's 24HOP session but could not make it. I didn't know what Sargability meant at the time and thought I will google it.

And here is what I have found out thanks to the internet.

Here is a blog post which gives the history of how the word came into existence back in 2005 where Brad McGhee explains that the sargability is a real word but it is used a lot in the SQL Server world.

So what exactly does Sargable mean?
SARG is a contraction for Search ARGument ABLE as mentioned in Rob Farley's article.

I am looking forward for the recording of this 24HOP session. Meanwhile you can have a look at the posting by Rob Farley in his blog where he gives links to the resources he has mentioned in his presentation.

My takeaways from Adam Jorgensen's 24HOP session -- Zero to cube

Here are my takeaways from today's fantastic session of Adam


  • The first basic point was you can use "." instead of "localhost" to choose the localhost server.
  • Defining the attribute relationship was very clearly explained that the relatiosnhps should be from the lowest level to the highest level.
  • Proactive caching -- available in from SQL SERver 2008 but the refresh property is available in Excel 2007 but sometimes may not work properly.

The following two resources which are quite useful was also discussed.

As he says in the end ...

Even if none of this stuff helps you at the moment it's good to know they exist.

Because DBA-ing is like a box of chocolates, you never know what you're going to get :)

What are plan guides?

Just a while ago I was watching a video on sqlshare Creating a Plan Guide for a Parameterized Statement By Andy Warren . Only then I heard about plan guides. I didn't know what plan guides were. Here is my find from googling


In SQL Server 2005, there is a new feature called Plan Guides that can help out in some cases where you discover poorly performing queries that you don't have direct control over. Essentially, a Plan Guide allows you to add or modify query hints to queries on the fly, just before they are executed. Click here for a detailed article on plan guides by Brad McGehee.

MMC cannot open -- in Citrix

Today I had a problem with our citrix server, where in the Management Console was not opening as usual when I try to open any of the below processes. Citrix Access Management console, Event Viewer, Manage Server, Administrative tools etc.


but I could access the event viewer from another machine. Here is what the event viewer error message says.



Here are the steps I have been advised to follow by Aaron Mountford (gen-i consultant) to resolve this.

I have registered the two dlls as follows.


Click Start, click Run, type regsvr32 Msxml3.dll, and then click OK
Click Start, click Run, type regsvr32 %systemroot%\system32\inetsrv\wamreg.dll, and then click OK.

Convert a date to show AM/PM in SQL

Today I was working on a date column -- create_date. I wanted to show whether the row was created in the morning or in the evening i.e., AM/PM

This is what I did to achieve this.


SELECT rn_create_date, SUBSTRING(CONVERT(varchar(20), Rn_create_date, 22), 18, 3) AS Expr1
FROM tablename;



Here is the link to the BIDN blog where I have posted
If we are used to the Query Analyser of SQL Server 2000, we might find it frustrating that the query window does not automatically come up when you start SSMS.

You have to either press Ctrl+N or Click on New Query to start it up.

Here is a way to start up the New Query window automatically.

Click on Tools-- Options click on the + to exapnd environment and click on General.

The following screen comes up.




Click on the drop down beside start up and choose ' Open Object Exlpoer and New query'.

Click Ok. Next time when you open SSMS the query window will automatically be opened for you.

Here is link to the blog I posted in my BIDN blog.

Star Schema vs. Snowflake Schema

Star Schema

• Start schema is simpler and hence good to use for small data warehouses. The rules that apply here are as follows:
• Each dimension is represented by a single dimension table
• Each dimensional table is related to or linked to a fact table.
• The relation is merely a master and detail relationship with Primary key being the dimension and reference key in the fact table.
• When there are 5 or more dimensions referring to one fact table it appears like a star and hence the name star schema
• In terms of ease of use you need less complex queries and easy to understand
• This design has redundant data and hence hard to maintain and change.
• Lesser query execution time due to lesser number of queries


Snowflake Schema
• Snowflake schema starts like a star schema and more complex and hence it is good to use the snow flake schema for large data warehouses. The rules that apply here are as follows:
• Each dimension is represented by a two or more dimension tables
• Each dimensional table is not directly related to fact table
• Here the tables that describe the dimensions are normalised.
• In terms of ease of use you have to use more complex queries
• There is no redundancy and easy to maintain and change
• More query execution time because of more foreign keys

Building a cube without a data source

Sometimes we might have to build a cube without a relational data source. In this scenario, we can build a cube without a datasource focusing on designing the dimensions and measures and then BIDS can generate the relational schema that is needed to populate the cube.

The following are the steps to achieve this.

•Start a new analysis Services Project in BIDS.
•In the Select method to build the cube diablog box -- choose "Build the cube without using a data source".
•In the Define New Measrue dialog box -- define the measures and measure groups.
•In the Define New Dimensions dialog box -- define the dimensions and set the basic properties
•In the Define Time Periods dialog box -- Define the first calendar day, last calendar day, first day of the week and the time periods whether it is year, quarter, month, date etc.
•Specify additional calendars if needed
•In the Define Dimension Usage dialog box -- Specify how the dimensions relate to the measure groups in the cube.
•In the completing the Wizard dialog box -- Enter the cube name and click Generate Schema now tickbox. This generates the schema geneeration wizard.
•In the Schema Generation Wizard dialog box -- Specify the Data Source view name and this will create the new Data Source View.
•In the Connection Manager dialog box -- Fill in the Provider, server name, Logon to the server, Connect to database fields.
•In the Impersonation Information dialog box -- Use the Service account (is recommended)
•In the data source wizard -- Specify the data source name
•In the Subject Area Database Schema Options dialog box -- Specify the options, accept the defaults
•In the Specify Naming Conventions dialog box -- just accept the defaults.
•After the above steps are completed, the data source view is generated in BIDS
•Populate the data source with data so that this data can be used to populate the cube.
•The last step is to right click the relevant cube in the solution explorer and select Process. Accept all the defaults and click Run. This step extracts data from the data source view and populates the cube.
The cube is now ready for viewing.

Microsoft LogParser

Today I was frustrated with the built in error log in SQL SERVER 2005 and did some research and found the following link to Microsoft LogParser that can be used to search the error logs.

http://www.microsoft.com/downloads/details.aspx?FamilyID=890cd06b-abf8-4c25-91b2-f8d975cf8c07&displaylang=en



Log parser is a powerful, versatile tool that provides universal query access to text-based data such as log files, XML files and CSV files, as well as key data sources on the Windows® operating system such as the Event Log, the Registry, the file system, and Active Directory®. The results of your query can be custom-formatted in text based output, or they can be persisted to more specialty targets like SQL, SYSLOG, or a chart.

I have found this very useful

A sample query to search in the error logs is as follows:

Logparser.exe "select top 100 substr(text,23,9) as ESource, substr(text,0,22) as EDate, substr(text,32) asEMessage from \\d:\databases\MSSQLTEST\LOG\ERRORLOG.* where EMessage like '%database \'master\'.%'" -i:textline

Crystal reports not working from CRM system

today I had a problem where the crystal reports that render through the CRM system that print on a label printer were not printing. The error coming up was - "Error printing to crystal reports." Our system admin tried to reinstall the printer software, but that didnot fix the problem. Then I asked him to check whether it is the Microsoft updates.

Then he restarted the system and allowed the updates to go through and that fixed the problem.

I have attended the idera sponsored webinar on 'Top 10 Most Useful SQL Server DMVs' by Greg Robidoux

Here are my learnings of that webcast

What are DMVs
Dynamic Management Views are views and functions introduced in sql server 2005 for monitoring and tuning sql server performance.

Dynamic Management Objects (DMOs)
Dynamic Management Views (DMVs) -- can select like a view
Dynamic Management Functions(DMFs) --Requires input parameters like a function

When and Why use them
Provides information that was not available in previous version of sql server
Provides a simpler way to query the data just like any other view versus using DBCC commands or system stored procedures

Types of DMVs
  • change data capture
  • common language runtime
  • database mirroring
  • database
  • execution
  • full-text search
  • I/O
  • Index
  • Object
  • Query notifications
  • Replication
  • Resource governor
  • SQL Operating System

Get a list of all DMOs

select name, type_descfrom sys.all_objects where name like 'dm%' order by name

Permissions

Server scoped-- view server state

Database scoped--view database state

Deny takes prescedencedeny state or deny select on an object
People should have sys admin privileges

Grant permissions

grant view server state to loginname

grant view database state to user
deny view server state to loginname

deny view database state
must create user in master first

Specific types of DMVs

  • database
  • execution
  • IO
  • Index
  • SQL operatng system

Database for page and row count

select object_name(object_id) as objname, * from sys.dm_db_partition_stats order by 1

Tips 1851 -- mssqltips.com

Execution--- (when sql server is restart everything is reset)
sys.dm_exec_sessions-- info about all active user connections and internal tasks

sys.dm_exec_connections-- info about connections established

sys.dm_exec_requests-- info about each request that is executing (including all system processes)
Tips 1811, 1817, 1829, 1861

Execution--- Query plans
sys.dm_exec_sql_text--returns text of sql batch

sys.dm_exec_query_plan--returns showplan in xml

select * from sys.dm_exec_query_stats-- returns stats for cached query plans sys.dm_exec_cached_plans--each query plan that is cached

Exection -- example

select * from dm_exec_connections cross apply
sys.dm_exec_sql_text(most_recent_sql_handle)
select * from dm_exec_requests cross apply
sys.dm_exec_sql_text(sql_handle)

Select T.[text],p.[query_plan], s.[program_name],s.host_name, s.client_interface_name, s.login_name, r.* from sys_dm_exec_requests r inner join sys.dm_exec_sessions S ONs.session_id = r.session_idcross apply sql_text cross apply sys.dm_execsql_query_plan
select usecounts, cacheobjype, objtype, text from sys.dm_exec_cached_planscross apply dm_exec_sql_text(plan_handle)where usecounts > 1 order by use counts desc


IO

select * sys.dm_io_pending_io_requests can be run when you think that io can be a bottleneck select * from sys.dm_io_virtual_file_stats (null,null)

select db_name(database_id), * from sys.dm_io_virtual_file_stats(null,null) --shows io stats for data and log files -- database id and
file id -- null returns all datadb_name is a funtion to return the name of the actual
database rather than database id


Index (when sql server is restart everything is reset)
sys.dm_dm_db_index_operational_stats (DMF) -- shows io, locking and access information such as inserts, deletes, updates
sys.dm_dm_db_index_physical_stats (DMF) -- shows index storage and fragmaentation info,
sys.dm_dm_db_index_usage_stats (DMV) -- shows how often indexes are used and for what type of SQL operation
Tips 1239, 1545, 1642, 1749, 1766, 1789

Index examples
select db_name(dtabase_id), object_name(), * from operation_stats(5,null,null,null)

SSAS does not work if copied from another machine as a VM -- Why?

Did you know that even if you create an exact copy of the sql server virtual machine, the analysis services will not work?

I faced this problem last week.

The exisitng development machine (lets call it DEV1) stopped working and was giving lots of errrors.
So we thought that we will create a copy of the exisitng production system as a virtual machine and use that as the development machine and we created an exact copy of the production system as a virtual machine but gave it a different name (DEV2).
Then decomissioned the original development machine.

When I tried to access the sql server database on the new development machine (DEV2) the access was fine. But when I tried to access the analysis services through the management console, there was no response.

So I thought I had two options to make analysis services to work --

  • Option 1: Reload sql server from scratch and ssas and SSRS and then copy all databases and cubes from the production server.
  • Option 2: Try renaming the new development machine (Dev2) to the old development machine (Dev1)

Since option 2 was easier I thought I would try that first. And bingo the trick worked.

But I still don't know why analysis services does not work from a copy.

Can anyone of you help me understand why?

SSIS session in Auckland by Patrick

We had a really interesting session with Patrick of Pragmatic Works yesterday on the topic "Introduction to SSIS".

He has covered the following basic aspects of SSIS
  • Opening BIDS environment with a -NOSPLASH
  • Creating a small package with some package requirements -- Control flow, Data flow, Event Handler, package explorer
  • Deplying the created package
  • Scheduling a package

Here are my takeways from this session

Tip 1

You can use -NOSPLASH in the shortcut of the Visual studio icon to avoid the initial start up screen when you open Visual Studio

Tip 2

Data Connections can be created in two ways --

  • Via the Data Source on the right hand side of the screen of the solution. If the data source is created this way, it can be used by all the packages in the project.
  • Via the connection manager within the package itself. If this is used, the connections can be used only within that package.

Tip 3

Data Flow Taks can be created in two ways

  • Via the Control flow tab -- by dragging the Data flow task from the toolbox
  • Via the Data Flow Tab -- by just clikcing on the link available in this tab.

Tip 4

Always use OLEDB source instead of ADO.NET source for greater performance

Tip 5

In the OLEDB source tool always use SQL command instead of Table/view. Using the Table/View can slow down the SSIS package considerably.

Tip 6

When sql command in used, use the Preview button instead of the Parse Query button

Tip 7

You can use look up task and derived column task to redirect the un match rows to an error output.

Tip 8

If you use the row count task in the data flow tab that creates an unnamed variable, to name this varaible right click on the grey space on the control flow tab and name the variable.

Tip 9

You can right click on the control flow tab and click on the Package Configurations to configure the package. These configurations can be created as an XML file which can then be modified at deployment.

Tip 10

When you build a project and deploy, the package will be in the MSDB database of the sql server.

Tip 11

You can schedule an SSIS package using the SQL SERVER Agent or using dt exec command line.

Highlights of Visual Studio 2010 and Windows Azure Launch event

Today I have attended the Visual Studio 2010 and Windows Azure Launch event in Auckland. There were close to 1000 people for this event.

The first presentation on Visual Studio was done by Sam Guckenheimer. He took us through the Visual Studio product suite
  • He explained how this product can now reduce time wastage in the SDLC,
  • also how transparent the VS has become in terms of managing a project from a team perspective (using excel and sharepoint to monitor the team progress on a project)
  • how the use of layer diagrams helps communicate the design intent and later helps check the implementation against the design.

The second presentation was done by David Chappell on Windows Azure platform which is the Microsoft Cloud Computing Technology.

He said that there are two broad categories for cloud computing -- Cloud Applications and Cloud Platform.

He covered on the cloud platform of Windows Azure. Windows Azure is a platform where you ask for an application to run (instead of a VM) and the application will control how many VMs to run etc. The Windows Azure platform recognises if an instance failed and restarts a new instance automatically.

He also mentioned about the SQL Azure which is basically Sql server and this needs the TDS (Tabular Data Stream) protocol

Also talked about the applications of Azure as follows:

  • Apps that need massive scale
  • Apps that need high reliability
  • Apps with variable load
  • Apps with a short or unpredictable lifetime
  • Apps that do parallel processing
  • Apps that must fail fast or scale fast
  • Apps that don't fit well in an organisation's data centre
  • Apps that can benefit from external storage

He also mentioend the differences between the various cloud platforms (Amazon web services, Google App Engine, Force.com) and whether they are competitors or not.

Tools for collecting SQL Server instances

Due to the proliferation of personal firewalls, inconsistent network library configurations, and multiple-instance support, SQL Server installations are becoming increasingly difficult to discover, assess, and maintain.

Peter Ward from WardyIT Solutions while presenting in the SQL Saturday event at Auckland last weekend has asked all of us the following question:

“Do you know how many instances are there in your network?”

Only two people in the entire room have raised their hands.

He mentioned about the following tools being available for collecting sql server instances in a network.

Sqlping from www.sqlsecurity.com

SQLPing 3.0 is a free tool available which performs both active and passive scans of your network in order to identify all of the SQL Server/MSDE installations in your enterprise.
SQLPing 3.0 is designed to remedy this problem by combining all known means of SQL Server/MSDE discovery into a single tool which can be used to ferret-out servers you never knew existed on your network so you can properly secure them. .NET Framework v2.0 Required.

You can find more information about SQLPING here

Microsoft assessment and planning toolkit (MAP Toolkit)

MAP Toolkit is a free tool from Microsoft that does a lot more than just scanning the network and identifying all instances of SQL Servers. Some of the features are outlined below.
  • Secure, Agentless Discovery and Inventory
  • Generate Automated, Network-wide Readiness Assessments
  • Quickly Create Reports and Proposals
  • Capitalise on Cross-Sell and Up-Sell Opportunities
  • Shorten Your Presales Cycle, Increase Your Opportunities
  • Accelerate Server and PC Migration Planning
  • Leverage Virtualisation to Help Reduce Customers' Costs

For more information please click here

SQLIO
In the presentation Peter also briefly mentioned about SQLIO as a tool to measure SAN performance. I have googled for SQLIO and came up with the following.

SQLIO is a free utility from Microsoft that measures storage IO performance. The name "SQLIO" is horribly misleading, because it doesn't really have anything to do with SQL Server. There is a lot of information about SQLIO in the SQLServerpedia website

There may be lot of other tools out there. Please suggest me other tools if you can

Disable report filter selection in a Pivot Table in Excel

I had to work on disabling a field (report filter) on a Pivot Table in Excel 2007. I googled a lot on this and there was no straight forward answer. Hence thought of sharing my solution with anyone who wants to do the same thing

Here is the code that I have used to achieve this

Right click on the sheet where there is a pivot table and click on View Code
Add the following code

Option Explicit
Private Sub Workbook_Open()DisableSectorSelectionEnd Sub
Sub DisableSectorSelection() Dim pt As PivotTable On Error Resume NextSet pt = Selection.PivotTableIf Not pt Is Nothing Then pt.PivotFields("Sector").EnableItemSelection = False
End Sub


Save and reopen the file.

The following features cannot be saved in macro-free workbooks

The following features cannot be saved in macro-free workbooks

VB Project

To save a file with these features, click no, and then choose a macro -
enabled file type in the file type list.


To continue saving as a macro freee workbook, click yes.

That was the error I was getting today when I wanted to write a macro in Excel 2007.

In order to make an Excel 2007 workbook macro enabled, you need to save the workbook as .xlsm rather than .xlsx That solves the problem of the macros not being enabled.

PowerPoint Show (*.pps) file copies as a PowerPoint (.ppt) file when downloaded from the internet

Today we had a probelm on our website, where when you try to download a PowerPoint Show (.pps) file, the file was downloading as a PowerPoint Presentation (.ppt) file instead of a .pps file.

I have done some research on google and found the following solution to my problem.

  • In IIS Administrative Console snap-in, right-click the specific Web server where the .pps file is located, and then click Properties.
  • Click the HTTP Headers tab.
  • Click on Mime Types button in IIS 6.0
  • Click the File Types button in older versions of IIS.
  • Click New Type.
  • In the Extension box, type .pps, and then in the Content type (MIME) box, type application/vnd.ms-pps.
  • Click OK, and then restart IIS.

Checksum Vs. Hashbytes

What is Checksum?
Checksum is a function available in sql server 2005 and sql server 2008. It is intended to build a hash index based on an expression or column list.

Determining if two rows or expressions are equal can be a difficult and resource intensive process. This can be the case where the update was conditional based on all of the columns being equal or not for a specific row. Without checksums it is a long process of using innerjoins to identify the exact row to update in the update statements.

When is Checksum used?
When you need to compare the unique characteristics of an expression, columns or a table consider using the Checksum function.

When you have to update a row where many columns are compared to determine if the data is unique, use CHECKSUM function to build a unique value using checksum function and then compare the CHECKSUM values.



Example:



Hashbytes
What is hashbytes function?
HashBytes function was introduced in SQL server 2005 to simplify creating hashes in the database. It can convert values to MD2, MD4, MD5, SHA, or SHA1 formats.

When can you use a hash function?
Hash functions are a useful option to improve the efficiency of particular queries on large volumes of data. For example, on long strings of text, you can build a hash-index to perform efficient lookups or to speed up aggregate operations.


Differences between checksum and Hashbytes








Checksum
Hashbytes
Faster but can produce lot of duplicate values
Slower but efficient than checksum
Returns an int value
Returns a varbinary(8000)
Microsoft does NOT recommend using CHECKSUM for change detection purposes

Use Hashbytes for change detection purposes

Problem problems with Powerpoint

I had problems printing powerpoint slides this morning and here is an excerpt from an article on pptfaq.

Workaround

If you're willing to accept a slightly smaller slide image, you can print Notes Pages instead of Slides. Modify the Notes Master in your presentation:

  • Choose File, Slide Setup and set Notes pages to print in the same orientation as your slide pages
  • Choose View, Master, Notes Master
  • Select and delete the notes text and any other text placeholders you don't want to appear on your slide printouts.
  • Select and scale the slide image on the notes master to a larger size. NOT full page, but somewhat smaller. You'll need to find out what the trailing margin on your printer is and make the margins on both sides of your notes master at least that large.
  • Print a trial notes page from one of your slides. It will probably be off center. Go back to the notes master and move the slide image accordingly. It'll probably take several trial printouts to get right, but once you've got it nailed down, you should be able to get printouts of just your slides, properly centered on your inkjet printouts.
  • Once you've got it nailed, right click the slide image, choose Format and record the size and position of the slide image so you can use the same info in your other presentations.

Displaying powerpoint files on a website

I had trouble displaying powerpoint files on the website that I was working on. The problem was the link to the powerpoint file was a powerpoint 2007 show file (.ppsx). But when you clikc on the hyperlink, it was downloading with a .ppt extension

I have done some googling to resolve this problem and found that in order for links to PPTX/PPSX files to work, the two conditions must be met:
  • The user must have PowerPoint 2007, the 2007 Viewer or an older version of PowerPoint with the compatibility pack installed so that they can open PPTX/PPSX files in the first place
  • The web server configuration on your site must have the correct mediatype/MIME settings to serve PPTX/PPSX files as PowerPoint 2007 presentations.

The above is an extract from the article on pptfaq called Control how the browser opens powerpoint files

Outlook meeting request response myth busted

In outlook when a meeting request is received from the organiser, I was under the impression that when I accept the request and choose do not sent response, then the meeting request at the organisers end gets updated that the request has been accepted but the organiser will not be sent an email. This is a myth. I am sure most of us are under this impression.

When you choose do not send a response, there is no way outlook updates the request at the organisers end. So if you want to let the organiser know that you have accepted then you need to send the reponse when you have accepted.

The credit for this learning today goes to Vanessa Taylor -- our Executive Assistant to the CEO.

Convert date to text in excel

If you have a date in a cell, when you try to use it as it is for example in concatenation, the date gets converted to a number and does not retain the date format.

In order to retain the date format and still be used as text -- the formula that can be used is TExt(datecell, "dd-mm-yyyy")

Today I have attended the free webinar on T-SQL for SLQ Server from Pragmatic Works. This was a fantastic session by Patrick LeBlanc. Even though I had some experience in T-SQL I have learnt a few new things mostly the new features of SQL SERVER 2008. The recorded webinar can be viewed from the resources page and click on View Recording at the relevant webinar.

Interesting things I have learnt from this webinar are as follows:

  • If you don't want to type the table names you can drag a table into the query window from the object explorer.
  • If you don't want to type the field names you can expand the table and drag the columns folder into the query window from the object explorer and the list of fields of the table automatically appear in the query window.

    Set Identity_Insert On or OFF
  • You can update an ID column by setting the above variable on for a specific column. But remember to set the value to Off once you have updated the ID column as this works for one table at a time.
    Example:
    SET Identity_Insert tablename ON
    Insert INTO (IDcolumn, field1, field2)
    Values(6,ssss,zzzz)
    SET Identity_Insert tablename OFF

  • A very good description (illustration) of rather differnces between, Inner join, left outer join and right outer join.
  • The use of output statement
  • Grouping Sets feature of SQL SERVER 2008

Hope you also find this resource useful.

Do your backups for SQL server still exist?

Now that you have confirgured your backups on SQLSERVER, the backups themselves seem to be working, but are the files still where you think they are? How do you know they have not been moved, or worse, deleted to free up some space on your server? And when would you find out that the files were no longer there? If you are looking for the file to do a restore, and cannot find it, then it is too late.

Here is an tip from MSsqltips that shows you a simple way to check through the backup history to find the last full backup for each database and also to check that the file still exists where it is supposed to exist. Read More .............
