Dear sriram
bid & Price column is co related to each other
thats why i need to multiple them in Sets of Bid1*price1
Bid2*price2 & Bid3*price3
& my issue is related to finding max of set wise value column that is
Bid1*price1 = value1
Bid2*price2 = value2
Bid3*price3 = value3
and the corresponding bid & price column to derive that value column
Thanks
Sonal

A CREATE TABLE statement and a set of INSERT statements that together create the test data you are using.
We can do it ourselves, and sometimes do, but in general, if you want our help, it would be nice if you did some of the work....
