Auto increment problem

Hi,
I deleted a table which contains 200 rows using delete statement. In that
table i have used a identity column.
Now i inserted more data in to that table, but i am getting the identity
column series from 201........
So how can i reset the identity column to 1 without recreating the table.
Please help me...

Check out
DBCC CHECKIDENT
in Books Online (online help).
Note however, IDENTITY columns are only guaranteed to be sequential, NOT
contiguous
If you roll back a transaction for example, you will lose the contiguous
nature.
create table test_foo
(
id int identity (1,1),
foo varchar(15)
)
insert into test_foo (foo) values ('first row')
begin tran
insert into test_foo (foo) values ('second row')
commit tran
begin tran
insert into test_foo (foo) values ('third row')
rollback tran
insert into test_foo (foo) values ('fourth row')
select * from test_foo
drop table test_foo
