Reset Primary Column ID in Table

This will reset the primary column id number to 0, so the next time something is added it will have primary key id = 1

DBCC CHECKIDENT('YourTableName', RESEED, 0)

Useful in cases where you are doing a .. SET @NewID = SCOPE_IDENTITY() and a new ID is generated which you would like to reset.

Reference: MSDN – DBCC CHECKIDENT
