Besides, how does rollback work in MySQL?
MySQL transaction allows you to execute a set of MySQL operations to ensure that the database never contains the result of partial operations. In a set of operations, if one of them fails, the rollback occurs to restore the database to its original state.
Likewise, what is commit and rollback in MySQL? A COMMIT means that the changes made in the current transaction are made permanent and become visible to other sessions. A ROLLBACK statement, on the other hand, cancels all modifications made by the current transaction. Both COMMIT and ROLLBACK release all InnoDB locks that were set during the current transaction.
Herein, what is rollback in SQL?
SQL. In SQL, ROLLBACK is a command that causes all data changes since the last BEGIN WORK , or START TRANSACTION to be discarded by the relational database management systems (RDBMS), so that the state of the data is "rolled back" to the way it was before those changes were made.
Can we rollback after commit in MySQL?
No, there's no query that will "undo" a committed data-modifying query. If you have a backup of the database, you can restore the backup and use DBA tools (in MySQL's case, it's mysqlbinlog) to "replay" all data-modifying queries from the logs since the backup back to the database, but skip over the problem query.
