Can we rollback to original state after we have used DBCC CHECKIDENT to restart Identity column count?

Question

Currently on some operations I have to delete the old data and insert new one. But I noticed that inspite of deleting data the identity column did not reset and continued fr

Answer 1

The test code below shows that the DBCC action can be rolled back:

create table #t
(id int identity, val1 int)
go

insert #t (val1)
values (1),(2),(3)

select MAX(id) AS before from #t

begin tran 

    delete #t

    dbcc checkident (#t, reseed,0)

    select MAX(id) AS inside_tran from #t   

rollback

select MAX(id) as after_rollback from #t
dbcc checkident (#t, noreseed)
