Consider a scenario wherein you start the MySQL server and the following error message is displayed.
“Default storage engine is not available.”
When you encounter the aforementioned error message, you reinstall the server without removing its data directory. It runs fine when you run the MySQL server. But, when you attempt to open any table, it fails to open and an error message is displayed, that is:
“ERROR 1146 (42S02): Table 'Table_name' doesn't exist.”
Where, “Table_name” is the name of the table.
When you use the mysqlcheck command to solve the issue, the aforementioned error message still appears.
Cause
The error message appears because of having a corrupt database. And the MySQL database can get corrupt due to various reasons, such as virus infections, abrupt shutdown while the database is open, human errors, etc.
Resolution
First of all, you should backup the corrupted table to avoid any further damage to the database. Then, to repair the corrupted database you should use the Repair command to repair the corrupted table. In this command, you can use either the Quick or the Extended clause. As a last resort, check if you have a clean and updated backup. If yes, then restore the database with its backup.
However, there may be chances that the backup is not updated or the issue is still not resolved. In such cases, you should use a third-party mysql repair software to repair MySQL database. Such tools are read-only in nature that use fast yet sophisticated scanning algorithms to recover MySQL file.
