    model->setHeaderData(1, Qt::Horizontal, QObject::tr("Field 2"));
    model->setHeaderData(2, Qt::Horizontal, QObject::tr("Field 3"));
 
    if(model->lastError().isValid())
          qDebug() << model->lastError();
 
    QTableView *view = new QTableView;
    view->setModel(model);
    view->show();

QSqlQueryModel *model = new QSqlQueryModel;
    model->setQuery("SELECT  field1,field2,field3 FROM TABLE1");
