Re: START TRANSACTION COMMIT ROLLBACK
That is correct. Many db interfaces off programmatic abstractions of these facilities, but you may certainly just issue the statments.

Re: START TRANSACTION COMMIT ROLLBACK
If all the tables are InnoDB, XA isn't needed. It doesn't matter whether all tables are in the same database. On Oct 28, 2009, at 5:48 AM, Martijn Tonies wrote: Ah, works for InnoDB I see. Nice.

Re: START TRANSACTION COMMIT ROLLBACK
There seems to be some confusion about 'multi-db'.Within a single MySQL instance, assuming that all your tables are a transactional type (InnoDB isn't the only one), you don't have to do anything special to cross database boundaries. XA is required if you plan to spread your transactions out across multiple database instances. - michael On Wed, Oct 28, 2009 at 10:08 AM, Paul DuBois paul.dub...@sun.com wrote: If all the tables are InnoDB, XA isn't needed.
