Notification that your name is on the list?

Question

Python

import sqlite3
 
conn = sqlite3.connect("mydatabase.db") # или :memory: чтобы сохранить в RAM
cursor = conn.cursor()
 
cursor.execute("""CREATE TABLE albums
                  (title text, artist text, release_date text,
                   publisher text, media_type text)
               """)

I made it possible to register a name and mob through the bot. Base on sqlite but list on CSV. I can’t figure out how to check the lists for a name and then write it to the database as a mark and constantly update it like that.
I'll be glad for a hint
