Resolve ‘Found wrong record at 0’ error of MySQL


Sometimes tables of MySQL database become inconsistent when the writing process to the data files is failed. This can happen due to number of reasons like improper shutdown, power failure etc. Some other reasons also include storage engine issues, application bugs and many more. Myisamchk and mysqlcheck are two important tools that can detect and repair corruption errors of MySQL tables.

If these utilities fail to perform the repairing task, then a valid backup is required which can efficiently restore the lost information and can prevent data loss. If the backup is not available then user need to use MySQL Repair software to repair the corrupted database and make it functional.

Consider a scenario, in which when user tried to check the consistency of a MySQL database using myisamchk, the database may report an error message which says –

“myisamchk: error: Found wrong record at 0, MyISAM-table ‘table_name.MYI’ is corrupted”

In this error message table_name.MYI refers to the name of the table and .MYI files are used by the MySQL database to utilize the index information of the database table.

This type of error message indicates that .MYI file is inconsistent due to corruption. In order to rectify this database table corruption and to restore the information’s user need to perform certain activities –

  • Execute ‘myisamchk’ command to repair and recover the data’s of MySQL database. But before running that make sure that MySQL Server is not running. Follow this syntax for that – ‘myisamchk --recover table_name.MYI’.
  • If the corruption issue persists then try to restore the database from a valid backup. But if none of the measures work, then remove the damaged database table and create a new one.

In order to prevent the data loss and to repair the corrupted database alternatively you can use MySQL Repair software to recover MySQL database. This tool effectively applies the recursive scanning algorithm to repair and restore the data stored in MyISAM tables and also sets a secure link with MySQL server while repairing the corrupted MyISAM tables. This tool is totally compatible with both MySQL storage engines i.e. MyISAM and InnoDB and has realistic user interface for easy and simple use.
