If you combine all these features with the open source database feature, you have got all the ingredients of a complete relational database management system (RDBMS). However, nothing is perfect in this world, and the same is true for this people friendly, open-sourced database.
At times, the MySQL database can get corrupt because of various reasons such as virus infections, power outages, hardware failure, abrupt exiting MySQL while the write operating is in progress, etc.
In such cases, you should replace the corrupted database with its updated backup. However, if the backup is not updated then you should consider using a third-party Repair MySQL software to recover MySQL database.
Consider a scenario wherein you are working on a
MySQL database. You have to insert few records in a table. Suddenly there is a power cut and the system shuts down abruptly. When the power is restored, you run the Insert query and it fails to execute. An error message is displayed, that is:
"Could not insert new word matches
DEBUG MODE
SQL Error : 1016 Can't open file: 'my_table.MYI'. (errno: 145)
INSERT INTO my_table (emp_id, deptt_id, desig_name) SELECT 4467, deptt_id, 0 FROM my_table_wordlist WHERE word_text IN ('content')
Where my_table is the name of the table you are working on.
The error message signifies that the Insert command is not possible on this table.
Cause:The most likely cause for this error message is that the when the system shuts down abruptly, the table gets corrupt as the Insert query was in progress. Because of this, the database is now inaccessible.
Resolution:If you have the updated backup of the database, then you should replace it with the corrupted database. Or else, you should use the following methods to repair the corrupted table:
Use Repair table command on the MySQL prompt.Use myisamchk utility on the Shell command line.
However, if the aforementioned methods are not able to resolve the issue, then you should use a third-party tool to recover MySQL database. Such tools use fast yet sophisticated scanning algorithms to perform MySQL recovery of corrupted databases.
