Right ? Commit works only in conjunction with InnoDB tables and transaction. That's what i understand. I thought when i make e.g. an insert into a InnoDB table, and that insert is not done completely (due to a crash, restart, what ever) it is rolled back automatically after the restart. Is that wrong ?
transactions are not about single queries, transactions are all about multiple queries when you want them all or nothing written
please do some homework and read https://en.wikipedia.org/wiki/ACID which is basic knowledge about databases
the crash safety of innodb has nothing to do with commits
