How to implement rank system

Post by deesh »

Hi friends,

Can any one help to me how to implent the rank for a 1000 members in a class from 1 to 1000

If two students get same marks based on Maths marks we have to decide which student rank is higher than second one.

Sort. With a secondary sort criteria as a tie-breaker if there's no such thing as a tie.

Rank is a display function. Most query languages support it, as do most business intelligence tools. Rank is not something you ought to be asking an ETL tool to do.
