Subj:   Regarding usage of index
 
From:   Prasad Kavil Kambrath

Experts,

I have a table T1 which has the primary index as combination of columns C1 and C2. When I select using the condition on either C1 or C2, it is not using the index for fetching.

But when I use both columns for condition, it uses the PI.

Why is this happening?


Thanks,

Prasad
