QSqlQueryModel edit table & direct query to the database

[TomASS]

Thanks!
That what I'm saing!


Allmost

I'ld like to excecute any query, so I've:

model = new EditableSqlModel;
model->setQuery("SELECT ID_t, ID_podmiot, ID_oddzial, Numer, Numer_zleceniodawcy FROM m_transporty LIMIT 0 , 30");

model = new EditableSqlModel;
model->setQuery("SELECT ID_t, ID_podmiot, ID_oddzial, Numer, Numer_zleceniodawcy FROM m_transporty LIMIT 0 , 30");

To copy to clipboard, switch view to plain text mode 

but in example there is:

void EditableSqlModel::refresh()
{
    setQuery("select * from person");
    setHeaderData(0, Qt::Horizontal, QObject::tr("ID"));
    setHeaderData(1, Qt::Horizontal, QObject::tr("First name"));
    setHeaderData(2, Qt::Horizontal, QObject::tr("Last name"));
}

void EditableSqlModel::refresh()
{
    setQuery("select * from person");
    setHeaderData(0, Qt::Horizontal, QObject::tr("ID"));
    setHeaderData(1, Qt::Horizontal, QObject::tr("First name"));
    setHeaderData(2, Qt::Horizontal, QObject::tr("Last name"));
}

I'd like to change query in setQuery automatyicly. I've tried use to

setQuery(this->query().executedQuery());

setQuery(this->query().executedQuery());

To copy to clipboard, switch view to plain text mode 

but it's empty
