Format Mysql data

Question

I have a problem when passing a date to a select. Using the form below, select me returns the data normally:

SELECT H.* FROM HORARIOS H
                     WHERE NOT EXISTS (
                           SELECT * FROM RESERVAS R
                                WHERE H.COD BETWEEN R.COD_HORA_SAIDA AND
                                      R.COD_HORA_PREVISTA-1 AND
                                      R.COD_VEICULO = 1 AND
                                      R.DATA_SAIDA = '2015-11-26')
                                ORDER BY H.COD;

But, if I try to pass to the d-m-a format as below, it does not correctly return the data.

SELECT H.* FROM HORARIOS H
                     WHERE NOT EXISTS (
                           SELECT * FROM RESERVAS R
                                WHERE H.COD BETWEEN R.COD_HORA_SAIDA AND
                                      R.COD_HORA_PREVISTA-1 AND
                                      R.COD_VEICULO = 1 AND
                                      DATE_FORMAT(R.DATA_SAIDA, '%d-%m-%Y') = '26-11-2015')
                                ORDER BY H.COD;

Someone could tell me why he won’t accept it this way?
