        [quote author="wenks21" date="1304148870"]so what should be there? :) thanks..[/quote]

        Just follow secretNinja's advice and remove ; because the << operator is overloaded for "qDebug":http://doc.qt.nokia.com/latest/qdebug.html

        You may also need to call text() because qDebug does not expect QSqlError:
        @
        qDebug() << db.lastError().text();
        @

            Make sure you have included all required headers and include the "QtSql Module ":http://doc.qt.nokia.com/latest/qtsql.html at your pro file:

            @QT += sql@

            If you are a newbie it is better to stick to some examples and tutorials :)

                I still have a question. Why is that when I re-run the program the console says that 'Cannot retrieve debugging output!'

                  Please check this thread from Qt Center: "Cannot retrieve debugging output!":http://www.qtcentre.org/threads/37438-Cannot-retrieve-debugging-output!

                  Please do not use a single thread for multiple question from different issues because after that it will be difficult to track down the main issue.

                  Best regards,
                  Leon
