RE: SQL Triggers and Multiple Member Database Files

["Wilt, Charles" <CWilt@xxxxxxxxxxxx>]

As far as I know, it can't be done with an SQL trigger.

Which would make sense since SQL doesn't have any concept of multiple members.

You have two options:
1) Change the program to use a temporary work file.
2) Use an RPG/COBOL/C program for your trigger.
