How to divide a summed field by another summed field in the same query.
Example: lets have the query "querySummary" which its field have been grouped already
SID SumOfCredits SumOfMarks
1 3 18
2 2 20
3 4 40
Group By Sum Sum
I want to add another field named "FAvg" to the same query that builds up of dividing "SumOfMarks" by SumOfCredits, so the the result should be as following
SID SumOfCredits SumOfMarks FAvg
1 3 18 6
2 2 20 10
3 2 40 20
Any help please ? many Thanks
