Qt connect to XLSX file with ODBC driver

Question

I have that code, that I took from Qt wiki:

QSqlDatabase db = QSqlDatabase::addDatabase("QODBC");
db.setDatabaseName("DRIVER={Microsoft Excel Driver (*.xls)};DBQ=" + QString("sht.xlsx"));
if(db.open())
{
    QSqlQuery query("select * from [" + QString("Sheet1") + "$]");
    // Select range, place A1:B5 after $
    while (query.next())
    {
        QString column1= query.value(0).toString();
        qDebug() << column1;
    }
}
else {
    qDebug() << db.lastError().text();
}

But it doesn't connect :( I can't understand why:

[Microsoft] [Driver Manager ODBC] Data source name not found and no driver specified, the default QODBC3: Unable to connect

Answer 1

It was nedeed tp specify full path and set full name as in ODBC:

DRIVER={Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb)};

As always stack was useless. Guys here can answer only on noob questions, every real problem will stay here without answer.

Answer 2

You must compile and put database driver dll in a subfolder named 'sqldrivers' near your .exe file. In your case this should be qsqlodbc*.dll. Asterisk is a Qt major version number.

Answer 3

you need to install the obdc excel driver for xlsx and add it in your connect string instead of the xls
