I searched in the internet but no success.

The kind of data that you want to save is not important. However, since this is such a common, and easy, task, I do not, for a minute, believe that you couldn't find anything.

I typed "RFID MySql Arduino" in the google search field, and got 104,000 hits. Surely one or two provided a clue.
