delete in wordpress query

To delete in a WordPress query, you can use the following code:

global $wpdb;
        "DELETE FROM $wpdb->postmeta WHERE post_id = %d",

Explanation: 1. global $wpdb; - This line allows you to access the WordPress database functions using the global $wpdb variable. 2. $wpdb->query() - This function performs a MySQL database query. 3. $wpdb->prepare() - This function prepares a SQL query for safe execution to prevent SQL injection. 4. "DELETE FROM $wpdb->postmeta WHERE post_id = %d" - This is the SQL query that will delete the data from the database table postmeta where the post_id matches the provided ID. 5. $post_id - This variable should contain the ID of the post you want to delete.

Make sure to replace $post_id with the actual post ID you want to delete.
