Re: QMQRY QQRYSRC issues group by and order by

Frances,

You should group on all the columns (fields) that do not have a grouping
function, thus
GROUP BY RPPRCL, RPYEAR, RPBTCH, RPNAME, RPREFA, RPCHCK, RPAPYR

In that example you do not need GROUP BY, as you do not any of the
functions SUM, AVG, COUNT, MIN, MAX. (I might have forgotten some).

With regards,

As many of you suggested earlier, I am trying to switch from query/400 (or

whatever it is these days) to Query Management queries.

I cannot use STRQM because the command is only in two prior release

libraries.

But, that's not the issue at the moment.

I'm following examples in the SQL Reference manual for small tests.
SELECT WORKDEPT, AVG(SALARY)
FROM EMPLOYEE
GROUP BY WORKDEPT
ORDER BY 2

and this example:
SELECT PROJNAME, PRSTDATE, PRENDATE
FROM PROJECT
ORDER BY PRENDATE DESC

My source is (I tried using Select * which didn't work either):
SELECT RPPRCL, RPYEAR, RPBTCH, RPNAME, RPREFA, RPCHCK, RPAPYR
FROM TXOVRPP
WHERE RPNAME = &NAME OR RPREFA > &NEGAMT AND RPREFA < &POSAMT
OR RPPRCL = 'B018034101'
GROUP BY RPPRCL
ORDER BY RPPRCL

I am calling it via a CL which worked for other examples. This is the

error I am getting - it's not consistent with the example from

the manual. Any ideas which is the problem? thanks
