well, it won't make you happy, but that is how it works on e.g. PostgreSQL. Torque uses the onDelete="cascade" attribute only for the SQL generation and relies on the database to do the actual cascade. >Dear List, >I am trying to create a cascade delete foreign key reference for mySQL >database sql script, using Torque 3.0.2, but it doesnt generate the correct >sql. >I have taken a look at the mySQL template vm velocity files, but can not >find any mention of "cascade delete". I looked at the Torque 3.1 tree and cascades are only supported for oracle, postgresql and sapdb (as far as I can see). The MySQL support is pretty much on the 3.23 level when the database engine had no cascading delete support. The problem with MySQL is, that the supported language has been greatly extended in 4.x. So yes. I think you're out of luck for MySQL > 3.23 ATM. Sorry. Patches welcome (but they must keep backwards compatiblity; so you probably would need to introduce a new database type, e.g. mysql4, based on mysql.
