Subj:   Re: Sampling

Hi Michael:

You present an interesting challenge how about using something like this:

     sel *from mkting.CIM7403_Customer_Base
     qualify count(*) over (partition by customer_no rows unbounded preceding) < 6;

Since the count(*) does not specify an ORDER BY there is no sort. The PARTITION BY breaks it up like the original GROUP BY in CSUM, but CSUM and the others required a sort. Now with this being said, it assumes that you are on V2R5.

Hope this helps.
