MySQL organizes all the data as tables, irrespective
You might encounter the similar error message while accessing an InnoDB table:
'#1033 - Incorrect information in file: ' .frm'
MySQL crashes after you receive this error message.
You receive this error message if InnoDB table is corrupted or damaged. An InnoDB table is stored as three files: .FRM (database table definition), .MYI (Index file) and .MYD (table data). This particular error occurs if .FRM table is damaged or corrupted.
To solve such problems, you should follow these steps:
Check the table for corruption errors. To do so, you need to use CHECK TABLE command with options like QUICK, EXTENDED, CHANGED etc. that can be used on the basis of check required. The basic syntax is:
CHECK TABLE tablename [options]
If table corruption is the issue, repair it using REPAIR TABLE command. Before using the command, you should make sure that your disk contains about twice as much disk space as of damaged table. REPAIR TABLE command can be used with options like QUICK and EXTENDED with the following syntax:
REPAIR TABLE tablename [options]
If above measures cannot repair the damaged table, check your backup status. If valid backup is available, delete the damaged table and restore from backup.
If no valid backup is present, you can make use of MySQL Recovery software. These are advanced tools to analyze and repair damaged MySQL tables. Using powerful scanning, these tools are also capable of maintaining database integrity. Moreover, these MySQL Repair applications come available with rich user interface.
