You have written on line 19: @qDebug(); << ...@ There shouldn't be ; there.

Yes, that ; must be causing the error.
Btw there are really nice articles about SQLite in "Forum Nokia.":http://wiki.forum.nokia.com/index.php/CS001504_-_Creating_an_SQLite_database_in_Qt

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.
