From D2009's DB.PAS:
function TStringField.GetAsString: string;
begin
Result := string(GetAsAnsiString);
end;
...also you can have a look at TStringField.GetValue(var Value:

and, of course at SetAsString.
The workaround (for the time being) is to use .AsWideString which
returns an Unicode string.
Also, since the above hard-cast is in DB.Pas (iow outside of our
control) there will be problems with TIBO layer.
Also, perhaps, D5/6 can be dropped. The polls indicate that after D2007
the vast majority of users are concentrated on D7/D2007. But if someone
is against please raise the hand.
to apply for the Weaver beta test? (see http://beta.embarcadero.com)
