Qt Code: 
  1. QSqlQueryModel *model = new QSqlQueryModel(ui->tableView_staffLog);
  2.     qry.prepare( "Some Query" ); 
  3.     if( !qry.exec() )
  4.         qDebug() << qry.lastError();
  5.     else
  6.     {
  7. 	while(qry.next())
  8.         {
  9.             model->setQuery(qry);
  10.             model->setHeaderData(0, Qt::Horizontal, QObject::tr("ID"));
  11.             model->setHeaderData(1, Qt::Horizontal, QObject::tr("Name"));
  12.             model->setHeaderData(2, Qt::Horizontal, QObject::tr("Depart"));
  13.             model->setHeaderData(3, Qt::Horizontal, QObject::tr("Car Reg"));
  14.             model->setHeaderData(4, Qt::Horizontal, QObject::tr("Srt Date"));
  15.             model->setHeaderData(5, Qt::Horizontal, QObject::tr("End Date"));
  16.             model->setHeaderData(6, Qt::Horizontal, QObject::tr("Contact"));
  17.             model->setHeaderData(7, Qt::Horizontal, QObject::tr("Photo"));
  18.             ui->tableView_staffLog->setModel(model);
  19.         }
