The only way I know to emulate a trigger is to use form events. Unless you
are using a different backend than JET. For instance, you could do this if
your database engine was MS SQL, Oracle, etc.
Triggers would sure be nice. Access is event driven and unfortunately tables
do not have events. If you are entering data directly into a table, there is
not way to automate something like putting a foriegn key into another table.
If you are doing appends or inserts into a table, you need to handle anything
trigger-like while you are doing it.
I'll add that sequences would also be nice instead of autonumbers.
