Greetings,
I know this is probably asked a thousand times, but I cannot find a
reference anywhere on the web site. If there is one, please point me there...
Is it possible to do LEFT and RIGHT OUTER JOINS? i.e.
SELECT * FROM foo LEFT OUTER JOIN bar ON foo.id=bar.id;
All I could find on the web site was that PostgreSQL supports a subset of
SQL92 and SQL3. Is there someplace that tells what that subset is?
Maybe I don't need the join if there is some other way... I'm trying to
work out a query to give me one row from the many side of a 1-to-many
relationship for each row in the one side; basically making a 1-to-1 by
ignoring extra rows in the many table. For instance, a table of customers
(the one table) have phone numbers (the many table). I want to display a
list of customers with a phone number, but only one number regardless of
how many phone numbers there are.
Any insight would be greatly appreciated.
Thanks,
Matthew
