I have a table with 2 colums:   Location    Word
that looks like this:
W1  Dust
W1  Dirt
W1  Soil
W1  Mud
W2  Rock
W2  Brick
W3  Fly
W3  Run
W3  Jump

Each location can have any number of words in it.  I have a total of 31 locations (W1 thru W31).

I need a select statement that will select 1 random word from each location  (i.e. returning 31 rows)

Can someone help me with this?  Thank you.
