Re: On Triggers and library lists.

Hi Charles,

Yes I usually prefer that method too but not all files are RPG access.
In particular there is one with a CLOB on.
I don't believe you can open files with CLOBs in native RPG.

Also the program is building JSON objects using the DB2 JSON_OBJECT
publishing function from data on the trigger after image for insert into
the CLOB so that all needs to be SQL.

But I agree, I have a particular preference for ExtFile when I can get

away

with it.

best regards,
Craig

I wouldn't use an override....

Instead, use the EXTFILE() keyword on the f-spec..

Sorry, but I'm really behind on my e-mail and I'm just getting caught up
on this thread.

Doesn't the library on the EXTFILE keyword have to be hard coded at
compile time? And wouldn't that mean it's useless for the point of this
thread--i.e., if the trigger can handle the same file in multiple
libraries, using EXTFILE would force it to update the file in the
specified library and not necessarily one in the same library as the file
causing the trigger to fire?

Thanks in advance for clarifying my understanding (or misunderstanding),
