Helen,

Thanks for the reply.

Actually I already use a stored procedure in exactly the way you
suggest. However it became a monster because it has to take care of
parametrized WHERE, ORDER BY, some JOINS and a few other things. And
it's still not finished... every week I need to add something so it
gets worse. That's why I was looking for another solution.

Speaking of your book - is it available for purchase as a PDF or some
other electronic form?

Eyal.
