How to recover accidentally deleted data

Navicat is a powerful database management tool, but users will inevitably encounter unexpected situations where data is accidentally deleted. If you encounter this situation, you can follow the following steps to recover:

1. Check automatic backup

Navicat will automatically create backup files for the database regularly. Therefore, users can check whether the backup files contain accidentally deleted data. The backup file can be found by following these steps:

• File > Database Utility > Backup
• at In the "Backup" tab, select the corresponding database and backup file
• Click the "Restore" button

2. Use binary log

If binary logging is enabled, deleted data can be recovered from it. The binary log records all changes made to the database, including delete operations. Users can use the following command to view the binary log:

<code>SHOW BINARY LOGS;</code>

Then, use the following command to recover data from the binary log:

<code>mysqlbinlog --start-position= <start_position> --stop-position= <stop_position> | mysql -u <username> -p <database_name></code>

Where:

• &lt ;start_position>: The starting position of the changes to be restored
• <stop_position>: The stopping position of the changes to be restored
• <username>: MySQL user name
• <database_name>: The name of the database to be restored

3. Contact the database administrator

If none of the above methods work, users can contact the database administrator for help. The database administrator may have other ways to recover deleted data, such as viewing transaction logs or using professional data recovery tools.

• Back up the database regularly
