Calculating rank not working - PHP Mysql : I have a DB Table `user_points` which contains user's points and i am trying to calculate ranking based on points. It is working fine for all users except users having 1 point. 

Higher points are, ranking should be higher as well. For example:

1000 points = rank 1

1 point = rank 1223

Following is the query. 

    SELECT id, mobileNo, points, FIND_IN_SET( points, (SELECT GROUP_CONCAT( points ORDER BY points DESC ) FROM users_points )) AS rank FROM users_points WHERE mobileNo = '03214701777'

What should i change to fix it?
