Is JOIN by CASE possible?
« on: June 16, 2010, 02:34:05 PM »
Is it possible to do the following?

Code: [Select]
SELECT `a`.`f1`,`a`.`f2`,`b`.`f3`, `s`.`f4`
FROM `a`
CASE `a`.`f1`
WHEN 1 THEN INNER JOIN `b` ON `a`.`fx`=`b`.`fz`
ELSE
INNER JOIN `c` AS `s` ON `a`.`fx`=`s`.`fz`

No. But following the logic, you are after a LEFT OUT JOIN
