This article will explain in detail how to recover mysql database data deletion, Xiaobian thinks it is quite practical, so share it with you as a reference, I hope you can gain something after reading this article.

Sometimes mysql performs a wrong update or delete, resulting in a large number of data error recovery methods. No transactions are opened and no data is processed. This is when you need to use the sqlbinlog tool.

sqlbinlog needs to be opened, and the specific opening method will not be mentioned.

Using sqlbinlog produces bin files that are required for recovery. The file records all operations of the database. (The operation of this method is to re-execute the statement executed before the database to achieve the recovery effect)

Specific steps:

1, first find the bin file, usually in the mysql data folder, ending in the form of.00000X.

2. Find the time point to restore. Use the statement mysqlbinlog file name (MySQLbinlog xxbin.000001) to view the content, and then find the corresponding specific time.

3. Export sql statement, use mysqlbinlog filename>sql file path example (mysqlbinlog xxxbin,00001>> a.sql| mysql -u root -p )

If you need to export--start--date -stop =''--date ='' at a specified time to export the statement executed at the specified time example (sqlbinlog --start-stop ='2015 -11-22 10:00:00'xxbin.00001> a.sql| mysql -u root -p ) This sentence means to export statements before 10 o'clock on November 22, 2015, whereas start is after the export time. Start and stop can be used simultaneously.

If multiple bin files exist, export as needed.

4, use mysql to execute the exported statement once.
