this.calcRTRDetails = new SimpleJdbcCall(dataSource).withCatalogName("score_rtr").
                     withProcedureName("calc_rtr_dtls").declareParameters(
                        new sqlParameter("p_repy_track",Types.ARRAY)    
                      ).returningResultSet("p_track_dtls",new RowMapper<String>() {

                        @Override
                        public String mapRow(ResultSet rs,int arg1)
                                throws sqlException {
                            // TODO Auto-generated method stub
                            return rs.getString(1);
                        }
                    } );

我收到以下错误

org.springframework.dao.InvalidDataAccessApiUsageException: Unable to determine the correct call signature - multiple procedures/functions/signatures for CALC_RTR_DTLS found [score_RTR.score.CALC_RTR_DTLS,score_RTR.score.CALC_RTR_DTLS]

可能是什么原因？
