Hi

Suppose I have a query:

Code:
SELECT * FROM users ORDER BY user_id DESC
and this returns 300 rows.

What I want to know is, is it possible (in MYSQL) to know whats the record number for the user_id 50?


I know I can run a loop in my php script and start a counter and get the record number with simple if() condition, but if there are 8000 records in my table, I dont want to iterate thru all the 8000 records...hence looking for an efficient SQL Query.


Pls Help
Thanks
