Using DBCC CHECKIDENT

DBCC CHECKIDENT is used to manually set a new current identity value for the identity column.

Example

The following example show the current identity value in the sty_id column in the [student table] table to a value of 5. Because the table has existing rows, the next row inserted will use 5 as the value, that is, the new current increment value defined for the column value plus 1.

use master

GO

DBCC CHECKIDENT ([student table], reseed, 5)

GO

Press F5 to execute it.

Now to check identity value insert some data into the table.

Insert into [student table] values('raj','97','D', 'nnb')

Go

Insert into [student table] values('Herron','57','E', 'kkd')

Go

SELECT stu_id

,[stu_name]

,[marks]

,[Remarks]

,[From]

FROM [master].[dbo].[student table]
