Par défaut JOIN migration from Oracle to MySQL

Hello,

I've two LEFT OUTER JOINS in the WHERE section in an Oracle script like:

select ...
from...
where
....
and PT1.ID (+) = bl.PARENTTYPE_1
and PT2.ID (+) = bl.PARENTTYPE_2
....


MySQL knows LEFT OUTER JOINS in the FROM section but two joins with the same table aren't accepted.

example:
select ...
from
tableA PT1 LEFT OUTER JOIN tableC bl ON (PT1.ID = bl.PARENTTYPE_1),
tableB PT2 LEFT OUTER JOIN tableC bl ON (and PT2.ID = bl.PARENTTYPE_2),
....

-> doesnt' work.


Exits a solution for this example? Other syntax possibilities?


regards,
Spiker
