Using Select Aggregate Statements
I am getting mixed response regarding the use of aggregate statements in select query. My concerns are:
1) Using aggregate function in select query or processing in internal table is more efficient ?
2) If it is database dependent (as some may argue ), for which databases we have to use aggregate function and for which we should avoid to use it ?
3) Is there any relevant study regarding this topic, I mean some statistics with the no of records, and the underlying database used.
