Marvin Simmons Updated On - 07 Mar 2019

MySQL is a popular database management system that is widely used for web databases. In MySQL databases, the MyISAM table is the default database engine that that is fast, reliable, simple to use, and allows full-text searching. The MyISAM table provides a variety of functions for managing the fields and indexes.

While accessing MySQL database tables, a user may encounter several error messages or the records may not be displayed in an appropriate manner. Such scenarios happen only when the database gets corrupted or damaged due to external and internal reasons. Under such scenarios, MySQL database records can be accessed by restoring the data from an updated backup. Incase no backup is available or backup fails to restore the required records, use a third-party tool to repair the damaged database.

User may even want to upgrade MySQL database tables to newer version to avail benefits of new privileges added in the updated version of MySQL database. Upgradation of tables may lead to complete or partial loss of data from the tables.
Some of the error messages may get generated when MySQL database tables get corrupted. The records saved in MySQL database tables become inaccessible after generation of such error messages. Also, such error messages pop up every time user attempt to view the records saved in the tables. Some of the error messages are as follows:

  • “Table is crashed and last repair failed”
  • “Table was marked as crashed and should be repaired”
  • “Table that was working is locked against change”
  • “Unsupported extension used for table”
  • “Incorrect key file for table”
