QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL"); db.setHostName("localhost"); db.setDatabaseName("csms"); db.setUserName("root"); db.setPassword(""); bool ok = db.open(); if(ok) { qDebug() << "Database connected." << Qt::endl; } else { qDebug() << "Database connection error." << db.lastError ()<< Qt::endl; } But failed. I am googling the last two days but no luck. Now I am here. I need help.
