How to connect to SQL Server 2008 with qt?

After trying for so much time, I finally managed to get this to work ... here's what I did :

QSqlDatabase db = QSqlDatabase::addDatabase("QODBC3");

db.setDatabaseName("DRIVER={SQL Server};Server=ITPL_PC1;Database=Test;Uid=sa;Port=1433;Pwd=*******;WSID=.");

db.open();

QSqlQueryModel *model = new QSqlQueryModel;

QString query = "insert into qttable(PID) values('ARINDAM')";
model->setQuery(query, db);

db.close();
