I suggest avoiding c level code for calling a SQLite DB - try a simple wrapper over SQLite - see https://github.com/JohnGoodstadt/EasySQLite
This will allow:
DataTable* result = [_db ExecuteQuery:#"SELECT * FROM answers"];
It feels like you need to use a LEFT JOIN statement to answer your actual query - if you add info about your table definitions and what data you are trying to get out I can help more.
