It sure does work if you run qry2. qry1 is needed for qry2 only and is not intended to be the solution. qry2 is the solution.
Anyway, I have found a query that gives the desired result in one query instead of two and no sub queries are needed...
SELECT tblTest.bo_id,
tblTest.Primary,
Last(tblTest.pro_cm_seq) AS SEQ,
Last(tblTest.Phone) AS PHONE_NUMBER,
Last(tblTest.effdt) AS EFFECTIVE_DATE
FROM tblTest
GROUP BY tblTest.bo_id, tblTest.Primary
HAVING (((tblTest.Primary)=True))
ORDER BY tblTest.bo_id,
Last(tblTest.effdt) DESC;

Scott,
This does not filter the correct records. I only need 1 primary number for
each bo_id...it gave me primary and non primary...and sometimes more than 1
number for the bo_id...I can create multiple tables/queries to get to the
data I need...but I'm still curious as to why/what access is interpretting
different each time it executes this sql.
Thanks,
Mark
