mySql implementation

Hey guys,
I have got a minecraft server at nitrado and I want my plugin to be connected to my mySql workspace. I was able to get a connection and with somebody else coede I was able write something in the db. Now I have got the problem that I can not "read" what's written in the db. I want to get the money of a player for exaple I have got columns with the quaries : Name: Fin; Tim and Money: 500; 300.

I don't get it, I am doing many stupid mistakes right at the moment -_- Of cause I could post my code, but I think that would just confuse everybody so I hope someone has got the time to give me a code to get the values written in my db. I would give u this mushroom for it
