Hi Walden,

I prefere external triggers over SQL triggers even though the second ones
are much powerful.

The reason is, to change a trigger, you need exclusive access to the base
table. If your company works 24/7/365 it's rather impossible to change a
trigger. Our external trigger programs are only wapper's around the "true"
tigger program. The old and new record are passed as data structures to the
called program or procedure. This called program can be changed without
requiring exclusive access to the base table.

In SQL-Triggers I can get access to the old and new record (or table) within
the trigger, but I have not found a solution yet to pass this information to
a called stored procedure. There are no datastructures like we know it from
RPG.

Thanks, I'd seen that. Unfortunately it's too much of a simple reference
book. 

I'm looking for some real world experiences. I've got the stored procs
created and everything seems ok, but since there's not much discussion
about them here I'm just wondering if people have seen problems. It
might just be that people aren't using them.
