No, I just tested it on an unjournaled temporary table I created using DECLARE GLOBAL TEMPORARY TABLE. Using FINAL TABLE worked fine.

And more than that - I’m pretty sure, that “final table” only works under journaling - which only seems logical.

The solution below will not work. The relative record number returned will be from the final table, not from the table that's being inserted into (FFFFFF). So if you insert one row, the RRN value will always be 1. If you did a multiple row insert, e.g.

VALUES (:v1),(:v2),...,(:vn)

then you would get the same number of RRN values as you specified for values in the VALUES clause, and the last RRN value would be equal to the number of values inserted.

Hi,

Sorry, I'm too fast to answer...
Change your first insert like this :
SELECT RRN(X)
INTO :RRN
FROM FINAL TABLE(INSERT INTO FFFFFF(f1, f2...) VALUES (:v1, :v2, ...)) AS X;

Hi Greg,

A solution may be, if you can know the first and the last raw added and if the file don't have REUSEDLT(*YES), using relative record number to delete them : DELETE FROM FFFFFFF AS X WHERE RRN(X) BETWEEN first_row AND last_row.

Unfortunately, the file does not have a unique key or auto-id field, and it is not currently journaled. It's one of the biggest files on our system @ 36 million rows. As a transaction file, rows are never deleted (only inserted).

Some more info
I have never used journaling before (no rollback or commit).
My procedure is inside a service program that updates other files (COMMIT=*NONE).
This service pgm is used all over the place.

So if I turn on journaling for this file would it journal all transactions? Or just those from my program? All other programs updating this file do so via RPG (not SQL).

For now, I have added an extra SQL statement to check for the condition before attempting to insert - but that only checks for the condition that I have anticipated.
This will most likely take care of any issue, but...

If your file has a unique key - this is the way to go. If your file has an auto-id field, you can retrieve the value of the given id after the insert, and delete the file.

But most probably, commitment control is the way to go - simply roll back after the insert - and it’s gone. Of course, old programs can use „nc“ and your program uses „cs“ - it doesn’t hurt.

Just because your ERP doesn't use commitment control, doesn't mean a
process you've written can't use it.

Unless the file isn't journaled...

You have the data you inserterted, I assume there's a primary or unique key.

I'm working with a legacy transaction file from our ERP (i.e.
Commit=*none).
My SQLRPGLE service program procedure inserts two records/rows into
the file (they are complementary rows - both are necessary)

If the first insert fails, I simply exit the procedure with an error.

But I'm not sure how to handle the situation where the first insert
is successful, but the second insert fails. If this occurs, I need
to remove the row I successfully inserted.

Is there some way to capture the exact row I inserted successfully?
Like maybe the relative record number? Or am I out of luck here.

TIA,
Greg
