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
You mean
SELECT ObjId,ElemId,count( distinct Objid,ElemId ) from Elems group by
ObjId;
?
