Many times i write stoted procedures with transaction blocks.
I have delete a row after begin transaction and in continue i
read from table the select statement get back the deleted row:
begin tran
delete mytable
where id = @myid
and seqid = 3
select sum(balance)
from mytable
where id = @myid
............
...............
commit tran
.... OR
rollback tran
the sum(balance) function has calculate the balance of row 3
I use SQL 7.0
Thanks

Because the delete and the select are part of the same transaction, you will see the virtually deleted row until the delete is committed. If you MUST have the select inside the transaction, use the deleted table and a NOT EXISTS clause to exclude the deleted rows.
