No. Updating the database only updates the database. Your favorites, SAME codes and other settings you have in the "Profile" settings (and display customization if you're on a SDS radio) will remain unchanged.
One word of caution:
If you read the radio, it will overwrite whatever you have programmed on the PC.
So, if you have put a lot of work on your favorites and other programming, don't blow it all away by accidentally writing over it.
