How to recover accidentally deleted tables in Navicat

Navicat is a powerful database management tool. During the operation, tables may be deleted accidentally. The following are the steps to recover accidentally deleted tables:

Step 1: Check the recycle bin

Navicat provides the recycle bin function to save deleted tables. First, check whether there are accidentally deleted tables in the recycle bin:

1. In Navicat, right-click the database node.
2. Select "Recycle Bin".
3. If the accidentally deleted table is in the recycle bin, right-click the table and select "Restore".

Step 2: Use binary log recovery

If the accidentally deleted table is not in the recycle bin, you can use binary log recovery:

1. Make sure the binary log is turned on. In MySQL, edit the my.cnf configuration file, find the binlog parameter, and make sure its value is ON.
2. Stop the database service.
3. Recover the table from the binary log file using the following command:

<code>mysqlbinlog --start-position=起始位置 --stop-position=停止位置 --base64-output --no-defaults > 恢复文件.sql</code>

• The start and stop positions can be found in the MySQL error log.
• The content of the recovery file contains statements for table creation and data insertion.

4. Import the recovery files back into the database:

<code>mysql -u 用户名 -p 密码 < 恢复文件.sql</code>

Step 3: Use a third-party backup tool

If the above method cannot recover the accidentally deleted table, you can use a third-party backup tool, such as MySQL Enterprise Backup. These tools can back up your database regularly so you can recover it in the event of an accidental deletion.

Tips:

• Back up the database regularly to prevent accidental data loss.
• Operate the database carefully to avoid accidentally deleting important data.
• If you cannot recover the accidentally deleted table by yourself, it is recommended to contact a database expert for help.
