Did you try an OUTER join (default is INNER):
LEFT OUTER JOIN b on a.id = b.id
LEFT OUTER JOIN c on a.id = c.id

Hi Koen,
Thanks for the reply. Ouetr join doesnt made any difference. I rewrote the Query like below


The Problem was.
1. First the join was made and then filtering. Filtering logic was specific to the tables b,c and even the joined records use to get dropped off.
Solution
First put the Filtering logic specific to tables b, c before join and then do the generic filtering on the joined records.

This solves the issue.

Thanks
Chandra
