Home -> Community -> Usenet -> c.d.o.tools -> Re: using a trigger to enter data into a child table.
The only problem is that the before insert trigger actually creates and inserts the "SSCA" number. I can actually get the after trigger to insert everything but the SSCA number. I think I am calling the variable wrong. Hmmmm.......... I'll spend some more time with it today.
Thanks alot for your help.
