Hello,
I have upgraded my DB to 7.0.3, but there is still the problem. I think that
it may be a bug.
Joining 3 tables was not possible...
It says "fa1 should be in aggregate too" !
While joining 2 tables gives wrong results ...
ie, if the results should be like this:
fa1 sum
----- -------
ali 100
omid 200
shaya 50
then I get this:
fa1 sum
----- -------
ali 350
omid 350
shaya 350
Any more idea ?
