Hi all,
I have a question regarding proc sql sintax.
I need to find top 5 rows in a query which contains group by.
In particolar I need top 5 for each aggegation groups and not 5 rows at all.
In Oracle sintax I think I could use "Partition By" over a given rank in order to apply this wish.
Could you please suggest me a workaround to use in proc sql or a specific function if existing?

I really thank you a lot in advance for your support!

KR

Daniele.
