mysql unique option prefix myisam_recover instead of myisam-_MySQL

The correct option prefix for the MySQL MyISAM storage engine recovery option is myisam-recover, not myisam_recover.

To set the recovery option for MyISAM tables, you can use the following syntax:

SET GLOBAL myisam-recover = option_value;

Replace option_value with one of the following:

• DEFAULT: The server uses the value configured in the my.cnf configuration file.
• BACKUP: The server automatically performs a backup of any MyISAM table that requires recovery.
• FORCE: The server automatically recovers any MyISAM table that requires recovery without performing a backup.
• QUICK: The server automatically recovers any MyISAM table that requires recovery, trying to minimize data loss.

For example, to set the recovery option to FORCE, you can use the following command:

SET GLOBAL myisam-recover = FORCE;

Remember that the myisam-recover option only applies to MyISAM tables, as InnoDB and other storage engines have their own mechanisms for recovery.
