Subj:   How to avoid Product join
 
From:   Varun Kore

Hi,

When i try to join two table A and B using a left join, of which A is a very large table (75 lac records) and B is a small table (3000 records), it is resulting in a product join. The join condition is on the primary index of table B.

Can anyone please suggest ways to avoid this product join. Any and all suggestions are welcome.


Thanks and Regards

Varun Kore,
