  • now I have define the object of QSqlQuery like this:“QSqlQuery query; query exec(......);"
    but why it shows the mistake of "error: ‘query’ was not declared in this scope.....";I spend several hours to find it why,but I'm failed.
    please help me,thanks..



  • 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.
