Hi,
I just stumbled over a slightly confused error message:
mydb=# select count(*),coverage_area from myschema.streets except select
cd as coverage_area from countryref.disks group by streets.coverage_area;
ERROR: column "streets.coverage_area" must appear in the GROUP BY
clause or be used in an aggregate function
As the query looks, streets.coverage_area is actually used in the GROUP BY.
I know how to fix the query, but I wonder whether it is worth the effort
to try improving the error message.
Thanks,
Markus
