SQL remove repeating rows

SQL remove repeating rows

SQL remove repeating rows

I have an issue with SQL and I just cant seem to figure out the approach to achieve the result I need....

I have the following record set and I am wondering how I can remove certain rows.

C1    C2    C3        C4
A    B        C        1
A    C        C        2
A    B        C        3
D    E        F        1
D    E        F        3
D    E        F        5
G    H        I        2
G    H        I        4
G    H        I        3

What I want is to be able to select out the rows for the repeatiung sets that have the largest number in Column4
So the result set would be like this

C1    C2    C3        C4
A    B        C        3
D    E        F        5
G    H        I        4

Any insight is greatly appreciated
