I'm trying to write a buy() function which would update user's stocks and his balance.
It is not something about SQL-specific syntax and the way I created and queried my new tables since I am able to run the same INSERT queries against my tables directly in sqlite and they work just fine
It is clearly not something about the server not being able operate with my new tables because with all other operation (e.g. SELECT, UPDATE, DELETE) it works just fine
It is something about my new tables though, as I am able to run INSERT queries against initially defined
users table, but not against my new tables
