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.
