So I have some data that looks like this.

`USERID1 USERID2`
    1        10
    2        20
    2        30
    3        40
    3        50
    1        10
    2        20
    2        30
    3        50

I want a query that produces the following

`USERID1     COUNT`
    2        2
    3        2

It's a group by query that shows me the count of unique USERID2 for each USERID1 that has more than 1 USERID2 associated with it. God I hope you aren't as confused as I am by that last statement.
