  • Subject: Re: UPDATE primary file with JOIN?

Yup.

Given two tables...

create table a (fielda char(1), fieldb char(2))
create table b (field1 char(1), field2 char(2))

You can do this.....

 update a
  set fieldb = (select field2 from b where field1 = fielda)

Notice that it is not a join and you can't do this in V4R2 and prior.
