MYSQL删除并回滚

Question

I have a problem.

Past month I have a user query:

DELETE 
FROM  table_name
WHERE name = 'test';

it deletes approx 100 rows which is working fine.

But now I need that the delete rows that were deleted are rolled back? Is there is any procedure to get all my rows back?

I am using mysql.

Thanks in advance

Answer 1

No. The rows are gone. MySQL has no built-in revision control constructs. If you are worried about this being a common occurrence, make sure to back up your database before you run these kinds of queries (look into mysqldump )

Answer 2

Have you checked in the mysqlbinlog? There could still be something of value in there.

And I'm sure you'd have a backup that you could restore from? :)

Answer 3

Currently you are lost, but in the future to prevent this:

From php.net using PDO

http://php.net/manual/en/pdo.begintransaction.php

<?php
/* Begin a transaction, turning off autocommit */
$dbh->beginTransaction();

/* Change the database schema and data */
$sth = $dbh->exec("DROP TABLE fruit");
$sth = $dbh->exec("UPDATE dessert
    SET name = 'hamburger'");

/* Recognize mistake and roll back changes */
$dbh->rollBack();

/* Database connection is now back in autocommit mode */
?>
