Correlated updates.

I wonder if you could help me with a piece of SQL? 



TableA has a column called Ref, which is unique.
TableB has columns called Oldref and Newref.



For every value of TableA( Ref) there is a corresponding value in
TableB( Oldref)



I wish to update every row in TableA so that the value of Ref is
updated to Newref (as listed in TableB).




Suggestions please.
