Pinal,

create table sample
(
id int identity(1,1),
name varchar(100)
)

select IDENT_CURRENT(‘sample’)
Here Identity as 1

begin tran
insert into sample(name)
select ‘udhaya’ union
select ‘ganesh’
rollback

select IDENT_CURRENT(‘sample’)
But here Identity as 2 . I have rollback, why not affected in identity column?

Yes identity can be ever decreasing, set Identity Increment to -1.
