We are building a large GPL'd application to manage network security (firewalls, VPN, etc - http://iscs.sourceforge.net) using Trolltech's Qt and their database drivers to our MySQL backend. We originally thought this was a Qt problem but it now appears to be a MySQL problem. We store the binary equivalent of dotted decimal IP addresses as int unsigned. We write and retrieve the variables to the database with unsigned long int variables from our Qt application. The variables appear to be written correctly to the database - at least when we query them with the mysql client. However, when we retrieve them, the Qt Variant class is not able to convert them to UInt values if they are larger than the maximum value of a signed int. Values that can fit into an unsigned int are returned properly. Large values always return 0, i.e., unable to convert the returned value to an unsigned int. We have the same results if we try to return the value as a string. If we change the database field to bigint, all works fine. Any ideas what the problem may be? We are using MySQL 3.23.56 and Qt 3.1.1. My test station is fully patched RedHat 9.0. Please pardon the cross post but I'm sure this is of interest to Qt database developers. -- John A.
