Oh i see now i realize my mistake. By the way would it
be possible to have manually update the sequence as
well .
For example :
ID name
--- -----
1 BT
2 BI
3 BU
4 BZ
User accidently deleted id 3, and i want to manully
create the id 3 again.
insert into myclass (id, name) values (3, 'BU');
I Found that , this id 3 is not created but a new id
is created by the trigger as 5 . Any workaround for
tis ?
