You can use the IN clause.
select a.* from miscchg A
where (a.ashpnbr, a.abldngd) in ( select b.ashpnbr, b.abldngd) from

I would like to run the following, but reduce the "B" file down to
distinct key values PRIOR to the join.
Can this be accomplished in one SQL step?
select a.* from miscchg A, miscchgtmp B
where a.ASHPNBR = b.ashpnbr
and a.ABLDNGD = b.ABLDNGD
Maybe using "IN"? But that only works with one column, not two as Ineed.
It appears that your question has already been answered, but I wanted to
inform you that it is possible use the "IN" clause with multiple columns in
a subselect, so here is another way:
Select * From miscchg
Where (ASHPNBR, ABLDNGD)
In (Select distinct ashpnbr, abldngd From miscchgtmp)
