Seems like this should be an easy question, but I just don't get it:
If I have CREATE TABLE Elems (ObjId INT, ElemId INT);
Is there a nice query to find the Number of Distinct ElemId's for each ObjId?
Motivation: Later I will want to add a WHERE ObjId IN (...) and join the Obj
describing table to
the results of this query.
Thanks,
Csaba Gabor from New York
