在 Oracle 存储过程中将 XmlType 转换为 CLOB

Question

在我的程序中，我的变量 l_outxml 包含一个 XMLType 值。我想把它转换成 CLOB 类型。我怎样才能做到这一点？如果我更改变量的数据类型，它会抛出一个错误：

PL/SQL: ORA-00932: inconsistent datatypes: expected NUMBER got -

谁能帮我做这个？

CREATE OR REPLACE
PROCEDURE "test_Dinesh_page_1"
(
i_LRE_PeerGroup_ID IN out number
)
as
l_outxml xmltype := NULL;

 BEGIN
    with xmldata as (
      select es.d_reportentity_id
      , es.d_reportperiod_id
      , es.avgoralhealthscore
      , es.ScorePercentile
      , es.CostPMPM
      , es.topClaimPercent
      , es.topClaimState
      , l.LKP_reportEntity_PeerGroup_id
      , l.d_PeerGroup_ID
      , rp.EndYear
      , rp.EndQuarter
         from   f_ReportEntityScore es
          join  LKP_ReportEntity_PeerGroup l
              on es.d_reportperiod_id = l.d_reportperiod_id
              and es.d_reportEntity_id = l.d_reportEntity_id
          join  d_reportPeriod rp
              on es.d_reportperiod_id = rp.d_reportperiod_id
          where l.LKP_reportEntity_PeerGroup_id = i_LRE_PeerGroup_ID      
    )
    select xmlelement("ReportPage"
      , xmlelement("PageNumber",1)
      , (select xmlforest(
          cast(round(x.avgoralhealthscore,0) as int) as "DentalScore"
          , x.ScorePercentile as "DentalREINPercentile"
        )
        from xmldata x
        where x.LKP_reportEntity_PeerGroup_id = i_LRE_PeerGroup_ID
      )
    )   
     into l_outxml
    from dual;
end;

使用 xmlelement(...).getClobVal() 以转换为 CLOB。
