Two ways to reset the identity of a table in sql server.

I know of the following two ways to reset the identity of a table in sql server.

You often tend to use dummy data during the course of your development.  If you have identity columns in your table, the identity number grows. 
So you might want to reset the identity to 0 before you go to production.

This can be done in two ways.

First way is to use the DBCC CHECKIDENT command.

To check what the next identity number is going to be   you can use the below command
This will give you a message – sample below

Checking identity information: current identity value '746', current column value '746'.
DBCC execution completed. If DBCC printed error messages, contact your system administrator.

If you want to reset the identity number to 0 you can use the below command

DBCC CHECKIDENT (tablename, Reseed, 0)

Second way is to use the Truncate command.
We always tend to use the delete command for deleting records.  This is oggd when you have child relationships.

You can use Truncate table tablename command after a delete command.  Truncate command will ensure that the identity of the table is also reset.

Do you know of any other ways to achieve this ?

Could not load folder contents - SSRS Report Manager

When I tried to access the report manager after a fresh installation of Sql Server Reporting Serivces 2016 using the url http://localhost/Reports , I received the below error.

By default the installation gives access to Builtin\Administrators. In order to resolve this error below are the steps that you can follow.
Step 1 Run internet explorer as Administrator and open the Report Manager URL http://localhost/Reports

Step 2 Click on Site Settings icon and then click on Security as shown.  You can see only one assignment of roles here for Builtin\Administrators

Step 3 Click on Add group or user assign the role assignment as shown below. 

Re-open internet explorer (non-admin) and recheck the url. You will not get the error anymore.

The first error that was thrown was  as below:
Exception deserializing the package "Access to the path 'C:\BACKup\Test\Test\bin\Development\Tcopy.ispac' is denied.".

Here are the steps that I have followed to resolve this.

Step 3  Open Task Manager and end any process of DTS.  as shown below.

Step 4  Delete the .ispac file that is created in the bin/Development folder

Hope these steps will help you resolve the build issues

DECLARE @JobID uniqueidentifier
DECLARE @LastRunTime datetime
Declare @JobStatus Varchar(100)
CAT.[Name] AS RptName
, res.ScheduleID AS JobID
, sub.LastRuntime
, CASE WHEN job.[enabled] = 1 THEN 'Enabled'
ELSE 'Disabled'
END AS JobStatus

dbo.Catalog AS cat
INNER JOIN dbo.Subscriptions AS sub
ON CAT.ItemID = sub.Report_OID
INNER JOIN dbo.ReportSchedule AS res
ON CAT.ItemID = res.ReportID
AND sub.SubscriptionID = res.SubscriptionID
INNER JOIN msdb.dbo.sysjobs AS job
ON CAST(res.ScheduleID AS VARCHAR(36)) = job.[name]
INNER JOIN msdb.dbo.sysjobschedules AS sch
ON job.job_id = sch.job_id
INNER JOIN dbo.Users U
ON U.UserID = sub.OwnerID
sub.LastRunTime > GETDATE() - 1 and  Cat.Name LIKE 'reportname%' 
ORDER BY U.UserName, RptName 
OPEN @RunAllReport

Print @ScheduledReportName --&' ' & @JobID
EXEC msdb.dbo.sp_start_job @job_name =@JobID
