Question

当我尝试运行一个返回表的函数时，我遇到了一个神秘的错误，我的函数代码就像

CREATE OR REPLACE FUNCTION FN_JOURNEY_SUMMARY(IN ENTITY INTEGER,
                                              IN VEHICLE VARCHAR2,
                                              IN SDATE VARCHAR2,

                                  S_DISTANCE        VARCHAR2(60),
                                  S_CUMM_DISTANCE   VARCHAR2(60),

                                  i_cntr            number);

    END;

        INSERT INTO GTT_V4JOURNEY_SUMM1
        SELECT * FROM FN_JOURNEY_SUMM_WEEK(ENTITY,VEHICLE, SDATE,EDATE,P_IS_DEBUG);

IF P_IS_DEBUG = 'Y' THEN
TM_END:=CLOCK_TIMESTAMP();
RAISE NOTICE 'THE START TIME WAS %',TM_START;
RAISE NOTICE 'THE END TIME WAS %',TM_END;
I_ELAPS_TIME:=EXTRACT(MICROSECONDS FROM (TM_END - TM_START))/1000;
RAISE NOTICE 'THE TIME TAKEN IS >>>>>>-------------->>>>>>> %',I_ELAPS_TIME;
END IF;
    RAISE NOTICE '*** end of all ***';
    RETURN QUERY SELECT * FROM GTT_V4JOURNEY_SUMM1 ;

END $FUNCTION$;

当我用：

运行该功能时

select * from FN_JOURNEY_SUMMARY(100,'NL01L0639','28/03/2014','23/06/2014','W',1);

这给我一个错误：

invalid input syntax for type timestamp: "28-Mar:28-Mar-14(13)"

存储在返回表的DTDATE列中，该列为character varying类型。

但是当我使用不同的名称编译相同的函数时，不会抛出任何错误并且它会顺利运行。

这是一团糟。它肯定不会像你声称的那样编译。

VARCHAR2和NUMBER无效data types in Postgres。

TM_START和TM_END应该是timestamp或timestamptz，而不是date。

P_IS_DEBUG应为boolean。

您的INSERT语句应该有目标列表。

在postgresql中运行函数抛出运行时错误
