Oracle SQL过程中的标识符无效

以下过程中出现错误（8,3）：PL/SQL:SQL语句被忽略，错误（8,10）：PL/SQL:ORA-00904：“XMLELEMENT”：标识符无效：

    CREATE OR REPLACE PROCEDURE GETXMLTREE
    (
      p_ESTABELECIMENTOID IN NUMBER  
    , MYXML OUT VARCHAR2  
    )
    AS
    BEGIN
    SELECT XMLELEMENT --line 8
    into MYXML
        ("root",
          (select dbms_xmlgen.getxmltype 
            (dbms_xmlgen.newcontextfromhierarchy
              ('SELECT level,
                XMLElement("item",XMLAttributes(osusr_kfa_estabele.id as "id"),
                  XMLElement("content", XMLElement("name", nomecompleto)))          
                  from osusr_kfa_estabele
                  start with osusr_kfa_estabele.id = p_ESTABELECIMENTOID 
                  connect by nocycle prior osusr_kfa_estabele.id = osusr_kfa_estabele.estabelecimetnopaiid' ))
          from dual))
    from dual;

    END GETXMLTREE;

有什么线索可以解释为什么会这样吗？

谢谢

您的收件人放错地方了。尝试：

SELECT XMLELEMENT --line 8
        ("root",
          (select dbms_xmlgen.getxmltype 
            (dbms_xmlgen.newcontextfromhierarchy
              ('SELECT level,
                XMLElement("item",XMLAttributes(osusr_kfa_estabele.id as "id"),
                  XMLElement("content", XMLElement("name", nomecompleto)))          
                  from osusr_kfa_estabele
                  start with osusr_kfa_estabele.id = p_ESTABELECIMENTOID 
                  connect by nocycle prior osusr_kfa_estabele.id = osusr_kfa_estabele.estabelecimetnopaiid' ))
          from dual))
    into MYXML
    from dual;

你的目标在错误的地方。尝试：

SELECT XMLELEMENT --line 8
        ("root",
          (select dbms_xmlgen.getxmltype 
            (dbms_xmlgen.newcontextfromhierarchy
              ('SELECT level,
                XMLElement("item",XMLAttributes(osusr_kfa_estabele.id as "id"),
                  XMLElement("content", XMLElement("name", nomecompleto)))          
                  from osusr_kfa_estabele
                  start with osusr_kfa_estabele.id = p_ESTABELECIMENTOID 
                  connect by nocycle prior osusr_kfa_estabele.id = osusr_kfa_estabele.estabelecimetnopaiid' ))
          from dual))
    into MYXML
    from dual;

DUAL中没有定义XMLELEMENT字段。好吧……那么我如何绕过这个事实呢？DUAL中没有定义XMLELEMENT字段。好吧……那么我如何绕过这个事实呢？
