Check you pro-file, It have next:
QT += core gui network sql // <<<

and
#include <QtSql>
#include <QSqlQuery>

in your source file.

On a sidenote: adding multiple punctuation marks at the end or in between your question does not emphasis the importance of your question, it just keeps some people away from reading your post at all, as such a behaviour can be seen as a major annoyance.

If you want to get the most of these forums (or forums in general) make sure you have read "this":http://www.catb.org/~esr/faqs/smart-questions.html at least once.
