QSql is a news for me …… But I open correctly my db (with error test), insert correcly my data, update correctly too …. but have some problem with these piece of code:     int p = 0;     QSqlQuery qy(db);     qy.prepare("SELECT id_pro1 FROM program WHERE pro1 = :pro1)");     qy.bindValue(":pro1", "ffff");     qy.exec();     qy.next();     p = qy.record().toInt();     ui->lcdNumber_2->display(p);     qy.clear(); I tray some method ( .value, .arg) but obtain only p=0 ….. I dont Understand why.
