How Do I Create a SQL Database in WordPress?

Creating a SQL database in WordPress is a fairly straightforward process. The first step is to create a new database using the WordPress administration panel. Once the database is created, you’ll need to create a new plugin file and add the following code to it:

// Import the necessary libraries. require_once( ‘wp-includes/db.php’ ); // Create the new database. $db = new WP_Database(); // Use the $db object to create the tables and columns.

$db->createTable( ‘posts’ , array ( ‘id’ => 1 , ‘title’ => ‘Sample Post’ , ‘body’ => ‘This is a sample post.’ )); $db->createTable( ‘comments’ , array ( ‘id’ => 2 , ‘post_id’ => 1 , ‘author’ => ‘John Doe’ , ‘comment_id’ => 3 , ‘date’ => ‘2012-01-01′ )); $db->createTable( ‘users’ , array ( ‘id’ => 1 , ‘username’ => ‘john.doe’ , ‘password’ => ‘password’ )); // Use the $db object to insert the data. $posts = $db->insert( ‘posts’ ); $comments = $db->insert( ‘comments’ ); $users = $db->insert( ‘users’ ); // Print the data. print_r( $posts ); print_r( $comments ); print_r( $users );.

Once the plugin has been created, you’ll need to activate it in the WordPress administration panel. You can then access the database using the WordPress API.
