管道函數返回表「不一致的數據類型：預期的％s得到％s」

我想創建一個管道函數來返回一個表，我似乎無法得到正確的語法。我跟着一些例子，並得到不一致的數據類型，我不明白爲什麼。我認爲它在某種程度上已經返回了與行定義不匹配的方式。任何幫助將非常感激。提前致謝。管道函數返回表「不一致的數據類型：預期的％s得到％s」

也許試試這個：

pipe row (ODSMAXVRSN_ROW(
    l_row.AUDIT_SLS_TRANS_KEY, 
    l_row.SLS_TRANS_KEY, 
    l_row.SLS_4_PART_KEY, 
    l_row.SLS_AUDIT_RVSN_NBR, 
    l_row.sls_trans_key)  
);

爲了調試插入

SYS.DBMS_OUTPUT.PUT_LINE( 
    l_row.AUDIT_SLS_TRANS_KEY ||','|| 
    l_row.SLS_TRANS_KEY||','|| 
    l_row.SLS_4_PART_KEY||','|| 
    l_row.SLS_AUDIT_RVSN_NBR||','|| 
    l_row.sls_trans_key);

爲了看到所有的值是否具有正確的數據類型。

更好的輸入值作爲DATE數據類型，不VARCHAR2，即

create or replace FUNCTION GET_ODSMAXVRSN (
    in_start_date DATE,in_end_date DATE) 
    RETURN ODSMAXVRSN_TBL PIPELINED IS 

... 

    where s.REC_CRT_TS between :in_start_date and :in_end_date 

... 

OPEN l_cursor FOR l_sql USING in_start_date, in_end_date;

或情況下，你必須堅持VARCHAR2，你也試試

create or replace FUNCTION GET_ODSMAXVRSN (
    in_dtFmt varchar2,in_start_date varchar2,in_end_date varchar2) 
    RETURN ODSMAXVRSN_TBL PIPELINED IS 

... 

    where s.REC_CRT_TS between :in_start_date and :in_end_date 

... 

OPEN l_cursor FOR l_sql USING 
    TO_DATE(in_start_date, in_dtFmt), 
    TO_DATE(in_end_date, in_dtFmt);
