RE: For the SQL gurus: Is this practical? Is it even possible?

Joe,

I modified you query only to match my field names and it seemed to work.
SELECT * FROM FOO WHERE
EXISTS (SELECT 1 FROM QUUX, BAR
WHERE QUUX.NINEDIGIT = FOO.NINEDIGIT
AND QUUX.FOREIGNTABLE= 'BAR'
AND QUUX.NINETEENDIGIT = BAR.NINETEENDIGIT AND
BAR.FWEEP = 2) AND
EXISTS (SELECT 1 FROM QUUX, BAZ
WHERE QUUX.NINEDIGIT = FOO.NINEDIGIT
AND QUUX.FOREIGNTABLE = 'BAZ'
AND QUUX.NINETEENDIGIT = BAZ.NINETEENDIGIT AND
BAZ.BOZ = 'SPAM') AND
EXISTS (SELECT 1 FROM QUUX, GAZONK
WHERE QUUX.NINEDIGIT = FOO.NINEDIGIT
AND QUUX.FOREIGNTABLE = 'GAZONK'
AND QUUX.NINETEENDIGIT = GAZONK.NINETEENDIGIT AND
GAZONK.GRIFFY = 3.141592653589793)
....+....1..
NINEDIGIT
1
********

At least, for the existance portion.
