Hi everybody,
I'm opening this thread to ask a couple of questions about the new InnoDB engine in the latest version of MySQL (now 5.5.8).
First of all, I'd like to know if there is now "full" support to transaction. With the term "full" I refer to the possibility to rollback any query executed, even those that modify the database structure: if I remember well, in previous versions of MySQL and InnoDB if, when inside a transaction, was executed a query like "ALTER TABLE ..." or similar, an implicit commit would take place. I wanted to know if such behaviour has been corrected.
Lastly, I wanted to ask if there is now support to deferred key constraint check, that is, the possibility to tell to the DB engine to defer key constraint checking until the end of the transaction.
Thanks for your attention.
