The following is an outline and description of the database tables created during the standard installation of WordPress. The database structure and the diagram below were last updated in version 4.4.
Because WordPress interfaces with this database by itself, you as an end user, shouldn't have to worry much about its structure. If you're Writing a Plugin however, you may be interested in learning how WordPress stores its data and relationships. If you have already attempted to use the existing WordPress API to access the data you need but have determined it's not possible without accessing the database directly, WordPress provides the wpdb class to make this task easy.
The diagram below provides a visual overview of the WordPress database and the relations between the tables created during the WordPress standard installation. The Table Overview below includes additional details on the tables and columns.
Please note that within the standard installation of WordPress no integrity between the tables is enforced e.g. between posts and comments. If you are creating a plugin or extension that manipulates the WordPress database, your code should do the housekeeping so that no orphan records remain in the tables e.g. by removing records in other tables with a set of SQL commands when foreign keys are deleted (Don't forget to remind users to backup before such operations).
In this article, we will explain how WordPress uses the database, including an intro to default WordPress database tables. We will also show you how to manage a WordPress database using phpMyAdmin, which will include creating database backups, optimizing the WordPress database, and more.
The information stored in a WordPress database includes posts, pages, comments, categories, tags, custom fields, users, and other WordPress settings. We will elaborate on this later in the tutorial when we talk about WordPress database tables.
Your WordPress database contains important WordPress settings, all your blog posts, pages, comments, and more. You need to be extremely careful when using phpMyAdmin, or you may end up accidentally deleting important data.
In newer versions of phpMyAdmin, it will ask you for an export method. The quick method will export your database in a .sql file. In the custom method, it will provide you with more options and the ability to download backups in compressed zip or gzip archive formats.
Keeping regular backups of your WordPress site is the best thing you can do for WordPress security. While the WordPress database contains the majority of your site information, it still lacks several fairly important elements, such as template files, images, uploads, etc.
Your WordPress database is the engine behind your website. With phpMyAdmin, you can tweak settings to improve performance, fix issues, or simply change things that cannot be changed from inside the WordPress admin area.
The first thing that you can do is to change the WordPress database prefix. This can significantly reduce the chances of SQL injection attacks on your WordPress database. This is because hackers often target sites using the default wp_ table prefix.

Hello, I am preparing to launch my first wordpress blog site under my first website. Testing and learning the blog setup I am wondering how the email stuff is working. I created a comment in response to a post and ticked the email me a notification when posts are done option. And when I made another post I received an email notification. Looking in the tables using phpmyadmin I can see the email address I entered with the comment stored in wp1_comments but cannot see where/how the fact is stored that an email should be sent to that address when a new post is made.
BackupBuddy works as a WordPress plugin and your database username and password are already stored in your WordPress configuration file. So it can automatically connect to your database without explicitly asking for your username and password.
We are happy to help you determine whether you need to access your database and help restore your site should accidents occur, however WordPress.com Happiness Engineers are not here to assist you with creating, modifying, or running database commands.
In my wordpress multisite, in the main website, I got error when I tried to update any post or widget. When I put my site in debug mode, I found many error with: The table is full for query UPDATE or INSERT as:
Another way to secure the WordPress database is to monitor logs for suspicious activity. Database logs enable you to track all user activity so that you can see all actions taken on your site, all requests made, and all errors encountered.
The plugin also comes with VaultPress Backup, enabling you to make real-time backups of your website, database tables, WooCommerce data, and more. Better yet, with the mobile app, you can restore your site from any location.
Over time, your database performance starts to slow down. This typically happens because the database has grown in size since you first launched your site. Therefore, the query execution time will get slower as your memory overheads increase.
To get started, open phpMyAdmin and click on your database to see the list of WordPress tables. Then, select the Check All option below the tables and use the With Selected dropdown menu to choose Optimize table.
You can either choose a Quick export, which is plenty for most websites, or a Custom export, which allows you to configure settings for the database export. Then, click Go, and the file will download to your computer.
Scroll to the Add User to Database section. In the User dropdown, choose your new user. In the Database dropdown, choose your new database. Click Add. A new screen will appear, allowing you to set permissions for the new user. Check the box next to All Privileges, then click Make Changes.
Now, navigate to phpMyAdmin in cPanel and select the new database you created in the left-hand list. Click the Import tab at the top. Upload the database file you saved earlier, then click Go.
One of the most popular ways to use phpMyAdmin is to edit post or page content from the interface. All you need to do is open phpMyAdmin from your hosting account. Then, click on Databases and select the database for your website.
Therefore, consider limiting the number of people with access to your database. In fact, you should make sure that only those you trust have these privileges. Additionally, you can educate them on how to interact with the interface to reduce the likelihood of accidents.
I have used ftp to download the existing site (Bluehost) and installed the contents into the new site on my VPS under the /wordpress directory. however, when I try to open a page (domain_name/worpress/index.php or other direct links) it just downloads an empty file to my computer. Clearly, the content is not there as it is all in the database structure.
So I have exported the database (which is an SQL database) using phpmyadmin on Bluehost and it now sits on my computer. I just cannot find out how to import it to either my server (for subsequent manipulation into place) or into the Wordpress site.
I looked into installing the myphpadmin script but it tells me I do not have any SQL databases so it will not do it. So presumably I have to convert the SQL to a Mariadb format? How? Then upload it to the server? How (ftp) and where? Then I assume I will be able to import it into the site as it will be listed as an importable database? Or are there any further steps?
Perhaps you would also need to manually adjust few option on wp_options table (for example, if domain name was changed) and adjust database settings in wp-config.php file (or simply not overwrite it on described above stage #3).
I am not database savvy. I learned to get to grips with phpmyadmin but cannot find a similar management tool for the MariaDB databases so I cannot even look to see if the domain has been changed or not within the databases or even if they are there in full. Is there a module or package I can add to my server to give me similar control to phpmyadmin?
BTW I tried to install the phpmyadmin script (as I read it can manage MariaDB databases) but webmin refused as it says there are no SQL databases on my server. Is it possible to overcome this so it can be installed?
