From within my PHP… Re: Multiple MySQL connections + transactions 1 Month Ago by Dani A slightly related question: Is it okay to use PHP's `mysqli::select_db()` function to switch databases in the middle of a transaction? This is what got me into trouble in the first place, when I started a transaction, performed some writes, switched databases, and then wrote to that second database, and then switched back, and performed some … Re: Multiple MySQL connections + transactions 1 Month Ago by Salem https://www.php.net/manual/en/mysqli.select-db.php I think the key word in all of this is "default". You can probably do what you want, but you have to refer to each DB by it's own handle. Using `select_db` is fine, if you only have one DB and you want to be lazy about referring to it. So you make it the default DB. But as … Re: Multiple MySQL connections + transactions 1 Month Ago by Reverend Jim As far as I know you can connect to more than one database at a time but you require a separate connection object for each one. Since queries go through the connection object you can't run a query on more than one db at a time. It seems to me that transactions are also connection based so you would have to manually roll back a transaction on A if … Re: Multiple MySQL connections + transactions 1 Month Ago by Dani I am already using multiple MySQL connections throughout the project, as well as select_db() in some other places. My question specifically revolved around if anyone can explain why select_db() implicitly committed the transaction, and then when done again to return back to the initial database, it did a rollback instead of commit. Re: Multiple MySQL connections + transactions 1 Month Ago by Reverend Jim In that case I can't suggest anything. I've never had to update multiple databases for any of the systems I set up. Re: Multiple MySQL connections + transactions 1 Month Ago by toneewa You're not suppose to switch databases with a connection mid-transaction. It's by design to rollback because it considers it a change to the session context. XA Transactions can be done if you use the InnoDB storage engine. Create separate PDO connections for each database. I wonder what kind of results you get with autocommit, serializable … Re: Multiple MySQL connections + transactions 1 Month Ago by Dani > If the databases are on the same server and use InnoDB, you can use fully qualified table names, and write to multiple databases on a single connection. That's what I ultimately started doing instead! Thank you so much for a definitive answer to my question.
