WordPress is built using PHP, a scripting language. PHP and uses the database system MySQL and MariaDB as its open-source relational database management system.
In the background, The WordPress database stores information like pages and posts and user information commenting on blog posts web site configuration settings, the settings for plugins and themes, and much more. The database could be damaged; your site could slow down or go offline if that occurs.
In this article, I’ll guide you through fixing your WordPress database and improving it to ensure that your site performs more efficiently.
What is the reason for fixing WordPress’ database? WordPress database?
WordPress websites can slow down or fail to load correctly for various reasons. Debugging will help identify the root of the problem, like damaged WordPress files, plugins, theme compatibility issues, and exceeded PHP memory limits.
There is a WordPress Debugging command, WP_DEBUG may be used to display PHP errors, and the SAVEQUERIES command is a great way to analyze database problems. To make use of these options, the only thing you need to do is include the following code in the website’s wp-config.php file. If you’d prefer debugging features, use WordPress plugins like The Query Monitor and WP Debugging to test your site.
define( ‘WP_DEBUG’, true ); define( ‘SAVEQUERIES’, true );
The most frequent error encountered in a WordPress installing process can be an “Error establishing database connection.” The reason that an owner of a brand new website is because the details of a database connection in the WordPress wp-config.php file are not correct.
It could also occur if critical WordPress files have been damaged or your web hosting provider is experiencing issues with the MySQL server. MariaDB server. For instance, a minor hosting service may not be configured to handle a significant increase in traffic, as it dramatically increases the number of processed database requests. Due to this, many visitors are likely to receive a Connection error.
The connection error you may see if your database connection details are incorrect.
A damaged WordPress database can slow or shut down your site altogether.
The corrupted database tables may occur because of a variety of causes:
- Incomplete Writing Power outages, server crashes, and unexpected server restarts may cause problems when the database is currently writing to a table in the database.
- Hardware Problems The servers on which the databases reside could suffer hardware failures as well as technical issues
- Software Bugs and Version Incompatibility Software bugs could be found within MySQL and MariaDB databases.
- Corrupted data The Corrupted Data Malware, viruses, and poorly written code may be a threat to the database data
Fortunately, MySQL and MariaDB allow you to repair corrupted WordPress databases. A CHECK TABLE operation will detect whether a table has been damaged, while the REPAIR TABLE command can correct tables if damaged.
- MySQL’s REPAIR TABLE command is compatible with three types of tables for storage engines: MyISAM, ARCHIVE, and CSV. The InnoDB storage engine comes with built-in repair functions executed on restarts; however, manually repaired repairs can also be performed.
- MariaDB’s REPAIR TABLE command is compatible with four different table kinds: MyISAM, Archive, CSV, and Aria (Aria was created to replace MyISAM safely. MyISAM). Other recovery options can be offered for InnoDB databases.
It is essential to note it is true that MyISAM was the initial default storage type used by MySQL, but the InnoDB storage engine is now the default storage option for both MySQL as well as MariaDB. It is worth noting that many consider the InnoDB storage engine self-repairing and self-optimizing; therefore, manual repairs to databases are only sometimes required. Visit Wikipedia’s page for different storage engine types to learn more.
Another option to remember is OPTIMIZE TABLE, supported with MySQL and MariaDB databases. It is a way to organize physically stored data in databases, reduce the amount of storage space needed, and increase the efficiency of I/O. In real life, optimizing the WordPress database will result in a speedier page loading time.
- MySQL’s OPTIMIZE TABLE command works with InnoDB MyISAM, OPTIMIZER, and ARCHIVE tables
- MariaDB’s OPTIMIZE TABLE command is compatible with InnoDB, MyISAM, ARCHIVE, and Aria tables
The database optimization is aided with the help of the following:
- WordPress Repair Tool Click on the “Repair and Optimise Database” button.
- PHPMyAdmin Select “Check all” and choose “Optimize table” from the drop-down menu.
- The WP CLI – Execute your command WP DB Optimize.
- Database plugins like WP-DBManager, Advanced Database Cleaner, and WP-Optimize can support WordPress Plugins Optimisation.

- Repair the WordPress Database Using PHPMyAdmin
PHPMyAdmin is a no-cost software for managing databases such as MySQL and MariaDB. A majority of web hosting companies support it. Other tools for managing databases work similarly.
You will see an option to phpMyAdmin within the control panel for your web hosting. If you launch phpMyAdmin, you’ll see the menu for selecting databases on the screen’s left side.

This process works with databases with storage engines supported by RePAIR TABLE commands like MyISAM.
In the screenshots below, you can see the WordPress database uses InnoDB, the InnoDB storage system.
phpMyAdmin lists all of your database tables.

InnoDB needs to provide it. REPAIR TABLE option. Therefore, instead of getting an indication that the tables were repaired, I get this message “The storage engine for the table doesn’t support repair.”
MySQL and MariaDB do not support InnoDB table repairs, but it’s not something to be concerned about as InnoDB self-repairs.
I recommend that WordPress users get acquainted with phpMyAdmin because it’s an essential tool for diagnosing WordPress issues. It’s also an excellent tool to analyze, fix, and enhance databases.
