Question

这是我的对象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))

这是表格def：

CREATE OR REPLACE TYPE FALCON.contacttbl AS TABLE OF contacts

这是我的流水线功能

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;

我在这里调用表函数时收到错误：

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

PLS-00382：表达式类型错误

由于我不知道如何定义xmltypedefs_spec.conttbl，我从流水线函数中删除了输入参数，只是让它动态生成假数据：

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;

子查询现在可以无错误地执行：

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( ) )

这告诉我xmltypedefs_spec.conttbl可能有问题，也许在SQL语句中使用集合类型？不确定。如果您更改了xmltypedefs_spec.pidtyp以使用falcon.contacttbl而不是xmltypedefs_spec.conttbl，该怎么办？好像你有一个包类型和一个对象类型正在做同样的事情？

Answer 2

xmltypedefs_spec定义与XML元素对应的记录类型。这些记录类型用于粉碎和构建XML。最初，XML没有使用重复元素，但现在必须。我试图获取xmltypedefs_spec.pidtyp的表，并使用pipelined函数从关联表中返回数据的“行”。我想以这种方式发送数组记录行来构建xml。

我为什么得到PLS-00382？
