Hola
No uso clientdataset, pero:

Código Delphi [-]
procedure TForm1.Button1Click(Sender: TObject);
begin
 ClientDataSet2.Close;
 with ADOQuery2 do
 begin
   Close;
   sql.Text:= 'select userid, checktime from checkinout where checktime = :fecha'
   Parameters[0].Value := DateTimePicker1.DateTime;
   open;
   ClientDataSet2.Open;
 end;
 
end;

Saludos
