What is the best way to fix a corrupt InnoDB table?

[kiran6495]

If you are dealing with a corrupt InnoDB table in MySQL, there are several manual methods you can try to fix the issue before considering automated solutions.

Manual Methods to Repair Corrupt InnoDB Table
Check and Repair Using MySQL Commands:

Open MySQL and run the following command to check for corruption:

CHECK TABLE table_name;
If corruption is found, attempt to repair it:

REPAIR TABLE table_name;
Note that REPAIR TABLE works for MyISAM tables but not for InnoDB.

Restart MySQL with Forced Recovery Mode:

Stop the MySQL service.

Edit the MySQL configuration file (my.cnf or my.ini) and add:

[mysqld]
innodb_force_recovery = 1
Start MySQL and check if the table is accessible. Increase the recovery level (1–6) if needed, but higher values may make data read-only.

Dump and Restore the Table:

If the table is still corrupt, export the data using:

mysqldump -u root -p database_name > backup.sql
Drop the corrupted table and recreate it.

Import the backup:

mysql -u root -p database_name < backup.sql
