Problem when checking if record exists in sqlite3 table. Where is the mistake?

Question

Python

The clans table was created, but when creating the .db itself, its filling was not specified in the on_member_join() and on_ready() functions.

if cursor.execute(f"SELECT owner_id FROM clans WHERE owner_id = {ctx.author.id}").fetchone() is None and cursor.execute(f"SELECT clan_name FROM clans WHERE clan_name = {rearray}").fetchone() is None:

Error:
sqlite3.OperationalError: near "1": syntax error

Answer 1

I did not delve into the code, but here:
WHERE clan_name = {rearray}
There are not enough quotes.
If you use doubles, then don't forget about shielding.
