Обсуждение: Cant group by non integer - ms access - odbc
Hi Not sure if this should go in pgsql-odbc or here, but todays my first real day on postgres, so I'll start here. I'm trying an aggregate query with groupby's on text fields. As per various FAQ's I have text fields NOT mapped to LongVARCHAR in the odbc dsn - but I get an error when I try an view the query --(cut from log)--> " message='ERROR: Non-integer constant in GROUP BY' " Any clues?? tia -- Glenn <glenn@pip.com.au>

What is your query (i.e. sql statement)? Can you give me the sturcture of the table(s) you are querying? ludwig __________________________________________________ Do you Yahoo!?

Hi Ludwig Seems I've actually asked the wrong q... My query was something like "SELECT f1,f2,count(f3) as countOff3, sum(f4) as countoff4,f5,"-" as f6 FROM mytable GROUP BY f1,f2,f5,"-"" Once I took out everything to do with f6, then it worked - however I need f6, as this forms a select to be inserted into another table. So now my question should be what is the postgres equivalent to this?

You never need to group by a constant, so this would work fine (and be
compliant with the standard, which your given example is not):
SELECT f1,f2,count(f3) as countOff3, sum(f4) as countoff4,f5,"-" as f6
FROM mytable
GROUP BY f1,f2,f5

Depending on what's happening upstream, it might also help to explicitly
cast the "-" to some specific datatype, eg
select ..., "-"::varchar as f6 ...
regards, tom lane
Shouldn't this be :
SELECT f1,f2,count(f3) as countOff3, sum(f4) as countoff4,f5,''-'' as f6
FROM mytable
GROUP BY f1,f2,f5,''-''"
2 single quotes. Double means a literal

Hi Ludwig
Seems I've actually asked the wrong q...
My query was something like
"SELECT f1,f2,count(f3) as countOff3, sum(f4) as countoff4,f5,"-" as f6
FROM mytable
GROUP BY f1,f2,f5,"-""
Once I took out everything to do with f6, then it worked - however I
need f6, as this forms a select to be inserted into another table. So
now my question should be what is the postgres equivalent to this?
Thanks
