Re: [PHP-DB] Multiple Inserts with mySQL
hmm, I guess that would work. There is no way to have mySQL check for integrity for me is there? I read in a SQL book a while ago about wrapping multiple inserts in a select statement, that way if any part of the statement failed the whole thing would be rolled back. From my research though, it doesn't look like mySQL supports this. Am I right here? So far it looks like your idea could be the most reliable suggestions I've gotten, so I'll start working on that for now.

10 Seconds searching in the MySQL Manual: http://www.mysql.com/doc/en/ANSI_diff_Transactions.html You have to use InnoDB tables, but this will work.
