Hi,
I was working on optimising a piece of code which was taking 10hrs + to execute 
and all.So my queries are..

#1) Saw a table where the "order of query" on the table and the "order of key"
are different . For faster results shouldn't they be in the same order.

for eg:

Select ...   where A.ID = ... and A.Name = ...

The Key order on this table A  NOW is Name & ID Order . 
Shouldn't they be in the order ID , Name ?..


#2) Can anybody recommend me any site , where I will get reliable information 
on Tuning PL/SQL ?.


With thanks in advance 

Ranjeesh
