Subject Trying to "update from" - Derby 10.1
Date Sat, 12 Jan 2008 20:30:44 GMT

I need to update several rows with data from another table.  I don't know the
data values at the time I write the statement.  I just want to copy from one
table into a different table according to some criteria.

In another dialect I'd write:

UPDATE a set a.foo = b.bar FROM A a, B b where a.x = b.y;

How do I do the equiv in Derb 10.1?
