How to remove duplicates in col1 and get group MAX in col2? / mysql Given the following table:

col1 Col2
A    1
B    1
C    1
B    2
B    3
A    0
C    5


how do I write a SELECT query (I just assumed has to be SELECT) that returns the unique items of col1 and the max values of col2, like this:

A   1
B   3
C   5
SELECT col1, MAX(col2) FROM mytable GROUP BY col1
