Get raise_application_error messages from errorstack? [message #662893] Mon, 15 May 2017 05:12 Go to next message

If I do a raise_application_error in one place of my program (DB backend), can I somehow retrieve this error through some errorstack in another part of my program (Forms application)?

For clarity, this is about a password_verify_function triggered by a DDL-statement to 'alter user'. It does all kinds of checks on the password and raises application error when the new password is at fault:

raise_application_error(-20001, 'This is a testerror');

The calling form (QMS0004F) does a 'forms_ddl'-call to do the 'alter user', which only returns a true or false boolean indicating the DDL statement either succeeded or failed. When false, I'd like to retreive the error and present it to the user. (I Don't necesarilly need a stacktrace, I just want to display the error and perhaps the errorcode.)

I tried some methods to get messages from the errorstack, like cg$errors.get_error_messages(), cg$errors.geterrors() and cg$errors.pop(), to no avail yet...

Well if forms_ddl returns a boolean on failure then the obvious thing to do is to not use it.
Stick the alter user in a stored procedure - you'll need to use execute immediate.
Call that instead, if an error occurs it'll be raised to the form.
