Comment (by rjasdfiii):
@akramipro - It looks like that query could end up with "DISTINCT" twice;
this seems wrong:
SELECT DISTINCT COUNT(DISTINCT groupbyvar) ...
Also, it is essentially wrong to mix DISTINCT and GROUP BY:
SELECT DISTINCT ... GROUP BY ...
(Since I don't know what happens after "return", I may be incorrectly
critiquing the code.)
