Try using a CTE to get miscchgtmp having distinct values, then join to the
With Distinct_miscchgtmp as (Select Distinct ashpnbr,ABLDNGD from
miscchgtmp where....)
select a.* from miscchg A, distinct_miscchgtmp B
where a.ASHPNBR = b.ashpnbr

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

Maybe using "IN"? But that only works with one column, not two as I need.
