mySQL : Values not inserting to my database

Hi, i am using mySQL. The code snippet below is what i have coded to make sure that the data are stored into the database. In the console, i get this "insert values into database. But it is not updating my datbases. Anyone know what wrong?? And i feel quite weird regarding the way i insert the value of monitorID and playerID. For monitorID, it is auto increment, so i am suspecting that it is the correct way to put 1. Another thing is the playerID, i don't know how am i going to get the iD? hmm

I understand we need to prevent cheating from client, which mean that the server will be responsible for updating the database. So for my case, my client will update the database. This is an for monitoring purpose. So i just want to record what the player have click. It is fine if i do it this way? Or i have to inform the server (using builtin master server) and ask the server to do the updating? Any advice or sugggestion?

Thank you for spending time to read. :)
