To repair a corrupted table in MariaDB, you can use the REPAIR TABLE statement. Here is the process step by step:
1. Before starting the repair process, it’s good practice to back up your database to prevent data loss. If you have already lost data, then you may want to look into data recovery steps.
1. Login to your MariaDB console. If you’re in Linux, use this command in the terminal:
\`\`\` mysql -u username -p \`\`\` You’ll then need to input your password when prompted.1. Identify the database that you’re interested in. You can view all available databases by using the command:
\`\`\`shell SHOW DATABASES; \`\`\`1. Select the database that includes the corrupted table:
\`\`\`shell USE database\_name; \`\`\`1. Now you can check the tables in the database:
\`\`\`shell SHOW TABLES; \`\`\`1. Once you have identified the corrupted table, use the REPAIR TABLE command:
\`\`\`shell REPAIR TABLE table\_name; \`\`\` The repair action may take some time, especially if the table or database is very large.1. After running the REPAIR TABLE command, you should see a message indicating whether the repair succeeded or failed. If the table still appears corrupted, then the corruption may be severe and you might want to seek additional assistance.
In some cases, you might need to also check and repair the server’s file system, as a damaged file system can also result in corrupted tables. Please ensure to take database backup regularly and also before using above steps.
These steps are using the terminal console, but you can perform similar steps with a database management tool UI like phpMyAdmin, SQLPro, MySQL Workbench, or others.
