So I would expect that I now can always double quote the selection
fields, but unfortunately that doesn't seem to be true.

From a graphical design, I get for instance:

SELECT "Opnamen.PatNr", "Opnamen.Datum"


Opnamen, PatNr and Datum are three separate identifiers, and have to 
be quoted separatedly (if at all), as in "Opnamen"."PatNr". 
"Opnamen.PatNr" is a single identifier, distinct from Opnamen.PatNr 
(which is two identifiers separated by period).


To illustrate, consider these valid SQL statements:

create table Opnamen (PatNr, "Opnamen.PatNr");
insert into Opnamen values (1, 2);
select
   Opnamen.PatNr, "Opnamen"."PatNr",
   "Opnamen.PatNr", Opnamen."Opnamen.PatNr"
from Opnamen;

The last query should return a single row with values (1, 1, 2, 2)
