Hi,

I have a table that records points that users are awarded. A user can have multiple rows in a table as points are awarded at different times. I am trying to write a SQL statement that will count the number of users that have total points greater or equal to 12 points. For example:

User       Points      Date
John        2             2013-12-01
Adam      4             2013-12-02
Mike       6             2013-12-02
John              6             2013-12-04
Mike              8             2013-12-05
John          6             2013-12-06
 
So in this example the count would be 2 (John and Mike).

Any help would be greatly appreciated. Thank you
