e.g.

SELECT * from A, B, C
  WHERE A.id = B.id
  AND B.id = C.id

hmm, but they're not related, A, B, C have no common columns

[parth]

sure that was just an example, as long as you have a way to query A, B, and C, you can add those as filters using WHERE / AND

oh I see, I didnt know you can have multiple tables in from clause like that
