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.

NO.

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

>From experience, the best way to tune PL/SQL is to scrap everything and
rewrite from scratch.
Get rid of count(*) and cursors in loops for a start.
