Question

I have data like this (col2 is of type Date)

 | col1 |        col2         | ------------------------------ |  1   | 17/10/2007 07:19:07 | |  1   | 17/10/2007 07:18:56 | |  1   | 31/12/2070          | |  2   | 28/11/2008 15:23:14 | |  2   | 31/12/2070          | 

How would select rows which col1 is distinct and the value of col2 is the greatest. Like this

 | col1 |        col2         | ------------------------------ |  1   | 31/12/2070          | |  2   | 31/12/2070          |
