Hi there..new to this. Pls be gentle.

Q. If I have a simple query like:

select * from bigtable
where product_code in ('abc','def','hij','klm')

I know that each of those product_codes will return a large data set. What I'd like to do is to run the same query but constrain the result set to a max rownum of 200.

Is this possible?

Thanks in advance...

Try this:
[CODE]
SELECT * FROM
(select ROW_NUMBER() OVER(PARTITION BY product_code order by product_code) AS RN, * from bigtable
where product_code in ('abc','def','hij','klm')) A
WHERE RN <= 200;
[/CODE]
