    Is there anyway to force some QSqlQuery values to be of a defined type?

    My problem:
    I have a sqlite database and one of the fields is of type VARCHAR, sometimes when I read it there are only numbers there and it may start with a zero. The problem is, Qt automatically assigns the type qlonglong to it and removes the first 0.

      It seems like sqlite is responsible for the wrong type, I couldn't find much about it.

      @QString string = "01234";
      QVariant var(string);

      qDebug() << var << string;@

      output:
      @QVariant(QString, "01234") "01234" @
