RE: SQL list column from multiple records on one line

Glad to be of assistance! I really like these newer things - LISTAGG saves our lives here. Another one I'm learning to appreciate is MERGE, oh, my, what an amazing functionality and practicality it has.

LISTAGG! Thanks for that reminder!

Implementer change management users may recognize the IMENLB table as the Environment Library List file.

SELECT LBENNM, LISTAGG( trim(LBNAME), ', ') WITHIN GROUP (ORDER BY LBSQNO) AS Library_List
FROM MKSIM/IMENLB
GROUP BY LBENNM
;

SELECT 'CHGLIBL (' || trim( LISTAGG( trim(LBNAME), ' ') WITHIN GROUP (ORDER BY LBSQNO) ) || ')' AS CHGLIBLcmd
FROM MKSIM/IMENLB
where LBENNM = '<some environment>'
GROUP BY LBENNM
;

Works like a charm! Thanks Vern!

I think LISTAGG can get the same result, and it involves a grouping, here it'd be grouped on the car manufacturer, I think. Much easier than this approach. I'll have to ask Kent about it.
