In MySQL 5.0.12 they changed the way MySQL handles joins to conform to the ANSI standard. http://dev.mysql.com/doc/refman/5.0/en/join.html "Previously, the comma operator (,) and JOIN both had the same precedence, so the join expression t1, t2 JOIN t3 was interpreted as ((t1, t2) JOIN t3). Now JOIN has higher precedence, so the expression is interpreted as (t1, (t2 JOIN t3)). This change affects statements that use an ON clause, because that clause can refer only to columns in the operands of the join, and the change in precedence changes interpretation of what those operands are." -- Pat Adams Digital Darkness Promotions Check out the Dallas Music Wiki http://digitaldarkness.com/tiki
