Here we go: http://dev.mysql.com/doc/refman/5.0/en/join.html "Before MySQL 5.0.12, the comma operator (,) and JOIN both had the same precedence, so the join expression t1, t2 JOIN t3 was intrepreted as ((t1, t2) JOIN t3). Now JOIN has higher precedence, so the expression is interpreted as (t1, (t2 JOIN t3))." -- Michael Fuhr
