Re: SQL - group by not working for me.

I have made one more "tweak" and am getting different results
I have changed the join to a left outer join, so those users that
have NEVER ran the job are listed...

however, in RPGLE, I am getting duplicate data instead of correct data
(If they never have ran the option, the previous records data is being
displayed)
example from STRSQL:

MNUPRF MNUGRP MNUOPT MNUCMD
ANORVELL M 4 CALL ORD500C
ASLOUGH O 6 CALL ORD500C
ASULLENS OE 1 CALL ORD500C
BCHURI ZA 23 CALL ORD500C
BHELMEID AO 1 CALL ORD500C
BPATEL ZA 23 CALL ORD500C
CHANCOCK M 8 CALL ORD500C
CLOOS M 8 CALL ORD500C
CNOBLE ZM 8 CALL ORD500C
CVONHOLT O 6 CALL ORD500C
CWEISS ZA 23 CALL ORD500C
CWIBERG M 4 CALL ORD500C
DACHARYA ZA 23 CALL ORD500C


MENUPF ANORVELL M 4.00 CALL ORD500C
MENUPF ASLOUGH O 6.00 CALL ORD500C
MENUPF ASULLENS OE 1.00 CALL ORD500C
MENUPF ASULLENS OE 1.00 CALL ORD500C -
MENUPF BHELMEID AO 1.00 CALL ORD500C
MENUPF BHELMEID AO 1.00 CALL ORD500C -
MENUPF BHELMEID AO 1.00 CALL ORD500C -
MENUPF CLOOS M 8.00 CALL ORD500C
MENUPF CLOOS M 8.00 CALL ORD500C -
MENUPF CVONHOLT O 6.00 CALL ORD500C
MENUPF CVONHOLT O 6.00 CALL ORD500C -
MENUPF CWIBERG M 4.00 CALL ORD500C
MENUPF DACHARYA ZA 23.00 CALL ORD500C

Thanks Michael, reducing to a single select worked.
I didn't show the group by in my code, because I couldn't get SEU to
accept it...

I didn't notice that you were doing a subselect with the strsql query.
Anyway the subquery isn't necessary. Just do this.

select mnuprf, mnugrp, mnuopt, mnucmd, mnuonm, max(mltimstmp) from
pdatalib/menupf
join pdatalib/menulog on mnuprf = mlnuprf and
mnugrp = mlnugrp and
mnuopt = mlnuopt
where mnucmd like (:fmtScanVals)
Group by mnuprf, mnugrp, mnuopt, mnucmd, mnuonm
order by mnuprf, mnugrp, mnuopt
for fetch only;

Subject: SQL - group by not working for me.

I have a query I can get to work in STRSQL, but not getting it
to compile in SQLRPGLE...

the premise of the query is to return the latest instance of a user
running a menu option. I have a menu file, and a menu log file.
for every menu file record I retrieve, I want to find the "Latest" time
the user ran that option...


I can't get my SQLRPGLE to accept the GROUP BY, or something else is
wrong!!!

here is my SQL that works in STRSQL:
select mnuprf, mnugrp, mnuopt, mnucmd, mnuonm, max(mts) from
(select mnucmd, mnuprf, mnugrp,
mnuopt, mnuonm, mltimstmp as mts
from pdatalib/menupf
join pdatalib/menulog on mnuprf = mlnuprf and
mnugrp = mlnugrp and
mnuopt = mlnuopt
where mnucmd like ('%ORD500%')
order by mnuprf, mnugrp, mnuopt) as list1
group by mnuprf, mnugrp, mnuopt, mnucmd, mnuonm


here is my RPG that won't compile...
each of the fields in my outer select have a "Column XXXXXX or
expression in SELECT list not valid" (SQL0122)

exec sql declare LOAD cursor for
select mnuprf, mnugrp, mnuopt, mnucmd, mnuonm, max(mts) from

(select mnucmd, mnuprf, mnugrp, mnuopt, mnuonm, mltimstmp as mts
from pdatalib/menupf
join pdatalib/menulog on mnuprf = mlnuprf and
mnugrp = mlnugrp and
mnuopt = mlnuopt
where mnucmd like (:fmtScanVals)
order by mnuprf, mnugrp, mnuopt)
ROWS for fetch only;


Thanks...
