How to call an SQL function with table return in java

How to call an SQL function with table return in java? You would need to call from java an SQL function that returns a table. I already did the following, however it has not worked for me.

CallableStatement fechaDeTurnosReservados=conexionBBDD
                .getConexionBBDD().prepareCall("{?=call horarioInicioTurnosReservados(?,?)}");
            
                
                Date sqlDate = new Date(vetanaAsignacionTurno.getDateChooser().getTime());
                
                fechaDeTurnosReservados.registerOutParameter(1, Types.DATE);
                
                fechaDeTurnosReservados.setString(2,dniMedico);
                fechaDeTurnosReservados.setDate(3,sqlDate);
                
                fechaDeTurnosReservados.execute( );

y esta es la funcion que estoy llamando

GO
CREATE FUNCTION horarioInicioTurnosReservados(@dniMedico int,@fechaIngreso date)
RETURNS TABLE
AS
RETURN(
     SELECT horaInicio
     FROM turno
     WHERE  dniMedico=@dniMedico and fecha=@fechaIngreso
     ) 
GO

Thanks a lot
