multi-table update

["Corey Kaye" <kayec@xxxxxxxxx>]

I'm wondering what is the best way to update one table based on another.  Can joins be performed for an update?

update table1 set table1.field2 = table2.field2 where table1.field1 = table2.field1;

The alternative seams to be:
select table2.field2 from table2;
update table2 set table2.field2 = $savedValue;

which is very slow....

Thanks.
