Tip: Please put that after mysql_connect and see if it is connected to database or not.

pawn Код:

if(sqlconn && mysql_errno(sqlconn) == 0)
    print("Connection to database was established!");
else
    print("Connection to database failed!");

Edit: I try to find the problem. But I can't, on my PC it work.

Edit #2: I reproduced your problem.

This isn't a MySQL Bug, it is a function which is defined already in another FS of GM. Change name of your callback or find it in other filterscripts or gamemode and includes.
