Creating a custom page on wordpress with a database call?

Question

PHP

Hello, my dears) I need help in writing SQL code in a PHP page (which will be in the WordPress template) to display information from the database by order number whether it has been completed or not, unfortunately it is very weak in the database. This is what the database looks like with the created table . Thanks in advance to everyone who replies!

Drop this thing. You are doing everything wrong. First of all, do not even try to do anything like this inside WP. Start with the basics.
