Hello!
I am using PostgreSQL 6.5 on a Debian/Linux 2.2 system. It all seems to
be just fine, but I have got into a problem with GROUP BY.
I have a query which worked OK until now (with all the previous versions
of PostgreSQL) but now it returns the following error message:
'Illegal use of aggregates or non-group column in target list'
So what has been changed at GROUP BY in 6.5?
Here is the whole query if you wish to take a look at it:
SELECT szl.*, sz.szaml_cim, sz.szaml_varos, sz.szaml_irsz, sz.szamlnev,
sz.programcsomagid, p.tulajdonosid
FROM dijbefizetesek szl, szerzodesek sz, programcsomagok p
WHERE (sz.szerzodesid = szl.szerzodesid)
AND (p.p_azonosito = sz.programcsomagid) AND (szl.osszeg > 0)
AND (szl.trdate >= 19990531) AND (szl.trdate <= 19990531)
AND (szl.trnum >= 1) AND (szl.trnum <= 1000) GROUP BY trdate, trnum
Thanking you in advance!
Regards,
Tamas
