How do you do many to many table outer joins?

Question

I have 3 tables, foo, foo2bar, and bar. foo2bar is a many to many map between foo and bar. Here are the contents.

select * from foo
+------+
| fid  |
+----         


        

Answer 1

FWIW, the question isn't really about a many-to-many: this could quite simply be done as a union.

A real many-to-many in SQL is a CROSS JOIN
