Every active database of any significant size will eventually experience some sort of corruption.
MySQL is the market leader for open-source databases. Most web software that uses databases supports MySQL and many of those packages support only MySQL.
Luckily, you can repair all of the databases in your database server with just one command:
mysqlcheck --auto-repair -e --all-databases -u<MYSQL_USERNAME> -p<MYSQL_PASSWORD> -h<MYSQL_HOST>
- --auto-repair means "If a checked table is corrupted, automatically fix it."
- -e means "Check and repair tables."
- --all-databases means "Check all tables in all databases." It can be replaced with --databases <DATABASE_LIST> to check/repair just one or a few databases.
