A fascinating article I’ve came across that has a number of aspects to study on. You may wish to look it over and see what you think.

MySQL tables are the most critical component of the database that allows you to store data in an organized manner. Thus, you can easily manipulate them and get effective query results. But sometimes, these tables give unexpected results and error messages. The reason could be table corruption, which needs to be restored from backup. However, if backup falls short of restoring data, you should use commercial MySQL Database Recovery applications.

You might receive the below error message in mysqld error log:

“[ERROR] Got error 127 when reading table “

You receive a series of such error messages.


The prime cause of this error message to occur is table corruption. A MySQL table might get corrupt due to any of these reasons:

? mysqld process is killed unexpectedly
? Hardware issues
? MySQL code or MyISAM/InnoDB code is suffering from bugs
? An external program and server is modifying the same table at the same time
? Unexpected system shutdown


To correct table corruption, you should follow these steps in order:

? You should first check the table for corruption using CHECK TABLE command. To run the command, make sure that the server is running. This check is used with following syntax:

CHECK TABLE tablename [options]

Here, options used are FAST, QUICK, MEDIUM etc.

? If CHECK TABLE command gives corruption errors, you should repair it using REPAIR TABLE command.

Before running the command, ensure that about twice as much disk space as of affected table is present on disk. The syntax is as:

REPAIR TABLE tablename [options]

Here, options used are QUICK, EXTENDED etc.

? Again, check the table for corruption.
? If table still remains corrupt, you should delete the damaged table if you have a valid database backup.
? In case, no database backup is available or it seems to be damaged or incomplete, make use of third-party MySQL Recovery utilities. These software are specifically designed to scan damaged MySQL databases and correct corruption errors.
