Re: Using transactions in MySQL + PHP

Sorry but I dont agree.. the question is not how to use commit/
rollback in a general way, but with PHP. If I only used MySQL i
wouldnt have this problem at all.


Commit/Rollback are SQL commands, not PHP. If you need to learn more about how to use them, you need a SQL newsgroup. Their use is not dependent on PHP or any other language. They work the same from the MySQL command line, for instance.

mysql_query(), etc. are PHP functions, and are appropriate for this group.

I don't think it's a good idea to use die() - is that what you want your
client to see?

I just used die as an example of abort/report failure, I wont use this
in my final script.

Additionally, I'm not sure die() will roll back your transaction.

For what I understood, (and I may be wrong), the data will only be
saved if COMMIT is done. So if one of the first 3 queries fail, no
COMMIT will be done, then no data will be saved.

Same occurs if first 3 queries are made with success, and the last one
fails.


As I said - I'm not sure on that. You need to check the MySQL newsgroups as to what MySQL does in this case.


There are other things you will need to consider with COMMIT and
ROLLBACK.

What things?
