    Description

      I read data from a database table. In the database table the number (hmilanguageid) is stored as 258059710618920545.
      My statement is:

      QSharedPointer<QSqlQuery> pQuery("SELECT hmilanguageid, to_char(hmilanguageid) FROM hmilanguage");
int fieldNo = pQuery->record().indexOf("hmilanguageid");
while(pQuery->next())
{
    qlonglong langid = pQuery->value(fieldNo).toLongLong();
    QString text = pQuery->value(fieldNo+1).toString();
    __int64 v = _atoi64(text.toStdString().c_str());
}

      I got under Windows 7, VS 2008 the following result:

      • langid = 258059710618920512
      • text = "258059710618920545"
      • v = 258059710618920545

      There must be an bug into the method toLongLong();
