Hi,
I'm trying to build a query to solve a fairly simple problem.
I have two tables (A and B) linked by a common ID. I want to
locate a specific record in A that is linked to two or more
records in B based on second field in B matching certain criteria.
I've tried every type of inner, outer, left, and right join
to accomplish this, but can't come up with anything that works.
EG: Select * from A inner join B on A.ID=B.ID where B.Val='25'
and B.Val='35';
This will rturn zero matching records since B.Val can't
equal 25 and 35 at the same time.
If I substitute "and" with "or", I will get multiple records
from A that are linked to either 25 or 25. I just want the
one record that is linked to both 25 AND 35.
Thanks for any help.
