Try a sub-select:
SELECT a.1,
b.2,
(SELECT count(*) FROM a, b WHERE a.3 = b.3;)
FROM a, b
WHERE a.3 = b.3;

I have a query in which I have joins.
something like
select a.1, b.2 from a, b
where a.3 = b.3;
how can I fetch the number of rows returned by this query.
normal count(*) doesn't work in this context as desired.
Thanks,
~Jas
