How to recover data in MySQL using rollback?

In MySQL, you can undo a previous transaction and restore data to the state before the transaction started by using the rollback operation. To perform a rollback, follow these steps:

  1. To start a transaction in MySQL, you can use the following statement:
START TRANSACTION;
  1. Perform a series of data operations in a transaction, such as inserting, updating, or deleting data.
  2. To undo previous transactions and restore data to the state before the transaction began, you can execute a rollback operation.
ROLLBACK;

After executing a rollback operation, MySQL will revert all changes made in that transaction and restore the data to the state it was in before the transaction began.

It is important to note that performing a rollback will undo all changes made in the entire transaction, so make sure that the data operation will not have irreversible consequences on the database before executing a rollback.
