How do I add a sub category so that the python_sqlite button is added?

Question

Python

I have a category that I can then add a product to.
I want to create a category, then add a subcategory to it, and a product is already in the subcategory
All this creates inline
keyboards

class Catalog:
    def __init__(self, name):
        self.name = name


class Product:
    def __init__(self, user_id):
        self.user_id = user_id
        self.product = None
        self.section = None
        self.price = None
        self.amount = None
        self.amount_MAX = None
        self.code = None


class AddProduct:
    def __init__(self, section):
        self.section = section
        self.product = None
        self.price = None
        self.info = None


class DownloadProduct:
    def __init__(self, name_section):
        self.name_section = name_section
        self.name_product = None


class GiveBalance:
    def __init__(self, login):
        self.login = login
        self.balance = None
        self.code = None


class Admin_sending_messages:
    def __init__(self, user_id):
        self.user_id = user_id
        self.text = None

Answer 1

@another_dream so your request is not formed correctly

$result = $mysqli->query("SELECT * FROM `entry` WHERE `descr` LIKE '%{$query}%' OR `content` LIKE '%{$query}%' OR `title` LIKE '%{$query}%'");

Answer 2

$result = $mysqli->query("SELECT * FROM entry WHERE descr LIKE %$query% OR content LIKE %$query% OR title LIKE %$query%");

My option, but the selection does not occur. $result is returned empty.
