Select distinct values from multiple columns

原文 2010-05-18 14:05:44 2 1 sql/ distinct

I had a table (Some_Table) with two columns:
AB
-------------------
1 test
2 test
3 test1
4 test1

i would like to return DISTINCT values for column B and it's associated value in column A (first in distinct set), so something like this:

AB
-----------
1 test
3 test1
