Maybe UNION is what you want
Select DEDEMP from DEDBAL
UNION
select INCEMP from INCBAL
and as the employee number is present on PRMAST, then you can ignore
PRMAST

We have three tables: DEDBAL, INCBAL, and PRMAST.
Each of these contains an employee number (DEDEMP, INCEMP, PREMP). We
want to produce output where an employee is represented in either
DEDBAL and INCBAL or both. (For the sake of argument, we can assume
that PRMAST is present for each employee).
I've tried various types of joins (LEFT OUTER, FULL, et cetera) and
have pored through the archives and GOOGLE and come up empty on a means
of doing this exactly right. (I'm convinced this is a common issue; so
my issue is probably my choice of search words - usually resulting in
too many hits).
Would some kind soul mind directing me to guidelines on how to write
the JOIN for this challenge?
