oracle解析xml(增加对9i版本的支持)

--方法1
 
SELECT * FROM  XMLTABLE('$B/DEAL_BASIC/USER_DEAL_INFO' PASSING
    XMLTYPE('<?xml version="1.0" encoding="gb2312" ?>&xml') AS B    
    COLUMNS USER_DEAL_ID VARCHAR2(50) PATH    '/USER_DEAL_INFO/USER_DEAL_ID',
    DEAL_INURE_TIME VARCHAR2(50)    PATH    '/USER_DEAL_INFO/DEAL_INURE_TIME',
    DEAL_EXPIRE_TIME VARCHAR2(50)   PATH    '/USER_DEAL_INFO/DEAL_EXPIRE_TIME',
    DEAL_CREATE_TIME VARCHAR2(50)   PATH    '/USER_DEAL_INFO/DEAL_CREATE_TIME');
 
 
 
--方法2
SELECT EXTRACTVALUE(VALUE(t), '/USER_DEAL_INFO/USER_DEAL_ID') i --编码
      ,
       EXTRACTVALUE(VALUE(t), '/USER_DEAL_INFO/DEAL_INURE_TIME') t -- 类型               
      ,
       EXTRACTVALUE(VALUE(t), '/USER_DEAL_INFO/DEAL_EXPIRE_TIME') t -- 类型
