Re: understand basics - multiple cars in a database - selection of one

hi all,

thanks for your feedback. I owe you some answers:
I'm beginner in programming both databases and applications. I'm using
PostgreSql and Qt / C++ for my application and I'm trying to learn.

list. or am I on a wrong list?
