QUESTION POSED ON: 28 April 2005
Is it possible to call an RPG LE program from SQL trigger procedure? Sample of SQL trigger:
Create trigger sampledb01.branch_in
before insert on sampledb01.branch
referencing new row as n
for each row mode DB2row
call sampledb01.brnch('i', n.branch_no,
n.branch_name,n.branch_mgr,
n.zone_no,n.region_no,n.status,n.telephone,n.address,n.enablers );

However, I get a message SQL0204 BRNCH in SAMPLEDB01 type *n not found.

The code above lifted from SG24-6503-01 Stored Procedures, Triggers and User Defined Functions.

Absolutely, you can call an RPGLE program from an SQL trigger. However, the RPG program must be registered as an external stored procedure with the CREATE PROCEDURE statement before creating the trigger. There are several examples of external stored procedures in the Redbook that you reference.
