QSqlDatabase db = QSqlDatabase::addDatabase("QODBC");
db.setConnectOptions();
QString dsn=QString("Driver=(SQL Native Client);SERVER=%1;DATABASE=%2;Trusted_Connection=Y es;").arg(servername).arg(dbname);
db.setDatabaseName(dsn);
if(db.open())

Have you installed your server with a named instance, instance being SQLEXPRESS? if not try..


QString serverName = "localhost";
QString dbName = "Test";

QSqlDatabase db = QSqlDatabase::addDatabase("QODBC");
QString dsn = QString("DRIVER={SQL Native Client};SERVER=%1;DATABASE=%2;UID=sa;PWD=;").arg(serverName).arg(dbName);

db.setDatabaseName(dsn);

db.open();
