Ordering Data From SQL/ASP

I have an application that rips data from an SQL server and displays it in
columnar form on an ASP page, using a Do until RS.EOF loop.

I wish to add 2 arrows to each column (up and down) and when clicked, orders
the data on the page by that column (up - A-Z and down Z-A etc.....)
Is this possible in ASP or would i need some Javascript/Client side code to
do this?

The problem is the ASP SELECT statement orders the data initially, i just
need to know how the user can re-order the data after it is on the page?
