• Open MySQL Workbench and select the database to be restored
• Click the "Management" menu and select "Data Export/Import"
• Select the database to be restored and the backup file path in the import option, and click the "Start Import" button

It should be noted that before restoring the database, be sure to back up the original database to prevent data loss or overwriting.

In summary, it is very important to learn MySQL database backup and recovery skills. By mastering the above skills and combining them with corresponding command line tools or graphical interface tools, data security and system reliability can be improved.
