MS SQL Server 2008 with Qt

[metRo_]

Hi,
I'm trying to connect Qt to MS SQL Server 2008 R2. I already have compiled the ODBC driver and I think it is ok.
This is the code I'm using:
@
qDebug() << "Drivers: "<<QSqlDatabase::drivers();
QSqlDatabase db = QSqlDatabase::addDatabase("QODBC");
db.setHostName("ze-w7\SQLExpress");
db.setDatabaseName("tempdb");
db.setUserName("sa");
db.setPassword("123456");
if(!db.open()){
qDebug()<<"ERROR: "<<QSqlError(db.lastError()).text();
} else {
qDebug()<<"Ok";
}@

But I always getting this error:
Drivers: ("QSQLITE", "QODBC3", "QODBC")
ERROR: "[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified QODBC3: Unable to connect"

What should I do?

Maybe instead of
@db.setHostName("ze-w7\SQLExpress");@

you must write

@ db.setHostName("ze-w7\SQLExpress");@

Or try write this code:

@QSqlDatabase db = QSqlDatabase::addDatabase("QODBC");
db.setDatabaseName("Driver={SQL Server};Server=ze-w7\SQLEXPRESS;Database=tempdb;");
db.setUserName("sa");
db.setPassword("123456");
if(!db.open()){
qDebug()<<"ERROR: "<<QSqlError(db.lastError()).text();
} else {
qDebug()<<"Ok";
} @
