WordPress/ClassicPress system requirements :

• PHP version 7.3 or greater.
• MySQL version 5.6 or greater OR MariaDB version 10.1 or greater.
• HTTPS support.

WP/CP uses it's own database structure and strongly discourages running direct SQL queries from the code. There is a special global variable $wpdb (an instance of a wpdb class ) which should be used to perform any database request.

If you want to use WP, you should probably convert your SQL database to match WP native structure (if it's possible) and then use $wpdb to manage your tables/rows/fields.

Otherwise if you really need a custom database structure, you might want to build a custom solution with some common PHP frameworks like Laravel ( Database: Getting Started ) or Yii2 ( Working with Databases ).
