Jim,

A couple of things that you CANNOT do with a trigger: o execute DDL statements
o issue COMMIT, ROLLBACK and SAVEPOINT statements.

Subject: Executing DDL from trigger

Hi folks-

I'm trying to simplify the process of creating a user account for a COTS package where I can't touch the code. There's some user configuration within the application, and of course there's creating the actual Oracle account. I created an insert trigger for the main user configuration table and used DBMS_SQL to execute a CREATE USER statement. The code works fine as a stored procedure, but as a trigger I get an error 4092 that commit not allowed in a trigger, presumably because of the CREATE USER DDL. I tried having the trigger execute the procedure but got the same error - actually I'd be disturbed if it didn't! I'm not looking for anything too involved here because a script will do the trick fine, just wondering if anybody has a simple suggestion to make this work. Thanks.

Jim
