爲什麼我會得到PLS - 00382？

Question

這裏是我的對象DEF：

CREATE OR REPLACE TYPE FALCON.contacts AS OBJECT (phone   VARCHAR2(50) 
    ,phoneusage  VARCHAR2(25) 
    ,phonetype  VARCHAR2(25) 
    ,email   VARCHAR2(150) 
    ,phoneext  VARCHAR2(25) 
    ,anytext   VARCHAR2(250)) 

下面是表DEF：

CREATE OR REPLACE TYPE FALCON.contacttbl AS TABLE OF contacts 

這裏是我的管道函數

FUNCTION get_pcontacts(p_conttbl IN xmltypedefs_spec.conttbl) 
RETURN falcon.contacttbl 
PIPELINED 
IS 
    l_contact falcon.contacts; 
BEGIN 
    FOR n IN 1 .. p_conttbl.count 
    LOOP 
     PIPE ROW(**falcon.contacts**(p_conttbl(n).phone, p_conttbl(n).phoneusage,    p_conttbl(n).phonetype, p_conttbl(n).email, p_conttbl(n).phoneext, p_conttbl(n).anytext)); 
    END LOOP; 
    RETURN; 
END get_pcontacts; 

我得到的錯誤，當我調用表功能：

FUNCTION get_pidxml(p_pidrec xmltypedefs_spec.pidtyp) 
RETURN CLOB 
IS 
    l_tmprec     CLOB; 
    l_pxml     xmltype; 
    l_bxml     xmltype; 
    l_pcontacts    xmltypedefs_spec.conttbl := p_pidrec.personalcont; 
    l_bcontacts    xmltypedefs_spec.conttbl := p_pidrec.businesscont; 

BEGIN 

--  l_pxml := get_contacts(p_pidrec, 'p'); 
--  l_bxml := get_contacts(p_pidrec, 'b');

PLS-00382：表達式類型錯誤

的因爲我不知道xmltypedefs_spec.conttbl是如何定義的呢，我刪除從管道函數的輸入參數，只是有它產生假數據飛：

CREATE OR REPLACE FUNCTION get_contacts 
    RETURN contacttbl PIPELINED 
IS 
    -- converts some structure to pipe of contacts 
BEGIN 
    FOR n IN 1 .. 5 LOOP 
     PIPE ROW( 
     contact( 
      '877-867-5309', 
      'Work', 
      'Cell', 
      'jenny@gmail.com', 
      n, 
      'WTF?' 
     ) 
    ); 
    END LOOP; 
    RETURN; 
END get_contacts; 

的查詢現在執行沒有錯誤：

SELECT 
    xmlagg(
     xmlelement("contactInfo", 
      xmlforest(
       phone AS "phoneNumber", 
       phoneusage AS "telecomUseCode", 
       phonetype AS "telecomequiptype", 
       email AS "email", 
       phoneext AS "phonenumberextension", 
       anytext AS "anytext" 
      ) 
     ) 
    ) 
FROM 
    TABLE(get_contacts()) 

這告訴我可能xmltypedefs_spec.conttbl有問題，也許在SQL語句中使用集合類型？不確定。如果將xmltypedefs_spec.pidtyp更改爲使用falcon.contacttbl而不是xmltypedefs_spec.conttbl，會怎麼樣？似乎你有一個包類型和一個對象類型正在做同樣的事情？

Answer 2

xmltypedefs_spec定義對應於XML元素的記錄類型。這些記錄類型用於碎化和構建XML。最初，XML不使用重複元素，但現在必須。我試圖獲取一個xmltypedefs_spec.pidtyp表，並使用流水線函數從關聯表中返回'行'的數據。正是以這種方式，我想發送數組記錄的行來構建xml。
