RE: SQL Question

Say File A has 6 records

For all six record in file A return x number of rows from file B where
the
key relationship matches (preferably random not an absolute
requirement).

I couldn't do this with one statement and ended up running several to
get
the result I wanted.

Do you mean something like:
SELECT KEYCOLUMN, COUNT(*)
FROM A
JOIN B ON OTHERCOLUMN = KEYCOLUMN
GROUP BY KEYCOLUMN

If you want a count from all records in A regardless whether B has a match,
change JOIN to LEFT OUTER JOIN.
