I have this SELECT:
SELECT (t1.f1+t1.f2+t1.f3) AS cGroup, COUNT(t1.f1) AS n1, COUNT(t2.f1) AS n2 ;
FROM t1 LEFT JOIN t2 ON <....>=<...> WHERE ......
GROUP BY 1

The resulting cursor has same value for both n1 and n2 which is not right because t2 has less number of these records. Is it possible to have such SELECT working OK?
TIA Mark
