Why does it give me no such column, although it exists?

Question

Python

I want to display a product where there is a user id next to it, here is the code, but I get an error: there is no such column

back_result = cur.execute(f"""SELECT * FROM {order} WHERE user_id = {user_id_q_bay}""").fetchall()

back_result = cur.execute(f"""SELECT * FROM {order} WHERE user_id = {user_id_q_bay}""").fetchall()
sqlite3.OperationalError: no such column: a535821263

Answer 1

user_id = '{user_id_q_bay}'

Answer 2

Because using string interpolation to form a query is a very bad practice.
