In that case, return 0 to the function and re call the random value generation to do all this again until you find a random number. Tip: You can save all new numbers inside a .ini file or something. Only numbers. When a player buys a new phone, get the values from that file and if none of them matches the number, assign it to new buyer.

No, I do not mean this. The whole purpose of affected rows is to avoid executing 2 queries (1 select to check if phone number exists and 1 update to set a new phone number). You execute only 1 UPDATE query and you know right away if the phone exists or updated the database without errors.

However, what I understood from ImTobi's first post if far from what he needs. So GTLS is right.
What if you try to call an offline player? What should happen?
