Hi,

I have a function like that:

function GebdatList() {
return DataObject::get("Steckbrief","","Geburtsdatum","","");
}

"Geburtsdatum" is a date-field and with this kind of sort the list is correctly sorted by the year.
Now I would like to sort the "Geburtsdatum" by month. I have done a lot of trials but nothing help me.

Have anybody an idea?

Thanks!
