    I use below script to reset my identity values (after we do huge data copy to testing environment)

    declare @idvalue bigint

    select @idvalue = 0

    select @idvalue = max(Tid) + 1 FROM Tbl_identity_fld1

    dbcc checkident(Tbl_identity_fld1,RESEED, @idvalue)

    go

    Recently i noticed that when i my table is empty this query passes me error. Hence i will need to add a check if my table is empty then dont run this script..

    do i check for NULL

    do i check for 0..

    Help please

    What error does it give you?

    If you want a check for empty table, just add an IF @@RowCount > 0 before the CheckIdent.
