Yes.  The common way to do that is to use a derived table, which is a subquery within the main query.

For example:

SELECT x..., derived...
FROM tablex x
INNER JOIN (
    SELECT b.product, ...
    FROM tablea a
    INNER JOIN tableb b ON ...
    INNER JOIN tablec c ON ...
    WHERE ...
) AS derived ON
    derived.product = x.product

Hi dravidnsr,

as already posted, with more info you can get better support, however here are some possible leads that may get you started on finding your own solution (assuming the two queries are in separate stored procs):

Use a table variable to store the result in query 1and pass that table variable to query 2 as a parameter
Use a (global or local) temporary table to store the result in query 1, then select from the temp table in query 2 (dont forget to clean up the temp table
Merge the two stored procedures into one
Define a view for the joins in query 1, make a list of IDs for the resulting records in query one and store them in a comma separated string. Pass this list to query two, parse the IDs out of the string and select records from the view based on the list of IDs.

Kind regards,

Bart.
