How to validate a value from a database?

Question

Python

There is a database on sqlite
It stores the following data: id, money
I want to make a 'Guess the number' game, almost everything is ready, what remains is to make a money check so that the user cannot enter a bet more than his balance in the database
I can't figure out how do this check

Answer 1

if bid > money:
return "error"

Answer 2

It stores the following data: id, money

If this is "balance", then compare with it. But if the user has several such records, then you need to add his code to this table and compare with the sum of all these records.
