Nerds????

Very hard to get the queries that return lots of rows. Getting ones that do huge numbers of reads is easier. Try

If very large data sets are needed, there's seldom much tuning that can be done through T-SQL or indexes. Usually, if you have to move extremely large data sets, you need to tune the hardware, or, in other words, throw money at the problem.

But that's just a general view on your open-ended question. Do you have a specific issue you're trying to solve?

select row_count , C.Text From sys.dm_exec_sessions ES ,sys.dm_exec_connections EC
Cross apply sys.dm_exec_sql_text (Ec.most_recent_sql_handle) C
where Es.session_id= EC.session_id

Not sure why you try to find out number of result sets. But above query can guide you.
