“In a move to make MySQL more profitable, Oracle has
dropped support for InnoDB storage engine from the MySQL Classic
edition which is available for free. So this free version of MySQL
– the classic edition is left with only one storage engine,
that is MyISAM. InnoDB Storage engine will be available only from
MySQL Standard edition and above which starts at US$2000.“A quick look at the MySQL product page shows that Storage
Engine: InnoDB is not available for the MySQL Classic Edition.”
