You're talking to human beings, not to a search engine. Please ask
your question on that basis - i.e. with a bit more background!
I'm *guessing* that you want an Outer Join. If you have TableA related
one to many to TableB, but you want to see all records in TableA
regardless of whether they have matching records in TableB, select the
join line in the query grid and choose Option 2 - "Show all records in
TableA and matching records in TableB".
If you're asking something else - please ask again, clearly.
