Creating a primary key in a trigger

I'd like to create a primary key value (incremental) within a trigger and set it in a primary key column.

Any idea anyone? Do I define my trigger as a On INSERT, Instead of INSERT? I tried both but it doesn't seem I'm doing things right.

You can use the identity column. Is there any different logic you are using for incremnetal primary key?

Not quite sure what you're trying to do here- are you not able to use IDENTITY as your auto-incrementing primary key field?

I think if you *really* want to do this you may do something like this:

Code Snippet

create trigger bbbb on bb
instead of insert
as

declare @.int int

select @.int = MAX(col1) from bb

insert into bb (col1, col2, col3)
select @.int+1, col2, col3

from inserted

HTH!
