Both work, but return only one record (there should be 4).
Or at least the code loop below only traverses once:
while not query.EOF do
begin
S := S + query.FieldByName('AppNo').AsString + #13#10;
query.Next;
end;
'CALL SelectDongleData 2485'
==> Exception: 'Cannot open a non-select statement'
Seems like SQLdb accepts EXECUTE in place of EXEC but when running the
call it fails to observe that more than one record is returned.
CALL is probably not recognized at all...
