UniDAC 6.2.8 - exceptions during TUniquery.Open when some query parameter values are unassigned

[dJabber]

Hello.

Database - IBM DB2 LUW 10.5

Reproducing steps
1. Put connection on the VCL form, then put TUniQuery and a button.
2. Implement button.OnClick handler

Code: Select all

  
procedure TForm7.Button1Click(Sender: TObject);
var
  i : integer;
begin
    query.SQL.Text := 'select * from mytable where sample_field=:field_value';//use arbitrary table from your DB
    query.Prepare;

    for i := 0 to query.Params.Count - 1 do
      query.Params[i].Bound := true;

    query.Open; ---->>>> exception here
end;

3.Execute application and press the button - the exception message appears.

если же присвоить параметру значение - исключения нет

If you assign value to query parameter, the exception does not appear.

Code: Select all

  
procedure TForm7.Button1Click(Sender: TObject);
var
  i : integer;
begin
    query.SQL.Text := 'select * from mytable where sample_field=:field_value';
    query.ParamByName('field_value').AsInteger:=1;
    query.Prepare;
    query.Open; ---->>>> исключения нет
end;

In 6.1.6. UniDAC version both wariants work without exceptions.

Developers, please, tell me what should I do in this situation.
