I have a employe table which has SlNo as Identity column. Currently the identity is 100. Now due to some reason last 50 rows (SlNo 51-100) has been removed. Now write a synatx to reset the identity to 51.

To Reset the identity we need to use the following statement. But caution to be taken that the identity column should not be the primary key.

DBCC CHECKIDENT('tbl_Employee', RESEED, 51) 

On executing the above query the output will be

Checking identity information: current identity value '18', current column value '51'.

DBCC execution completed. If DBCC printed error messages, contact your system administrator.
