Question

我有一个XML列：

<xmlList> 
   <XMLEntity> 
      <sug>ACHER</sug>
   </XMLEntity>

  <XMLEntity> 
      <sug>DOA</sug>
   </XMLEntity>
</xmlList>

sug只能包含枚举（ACHER或DOA）。我想检查是否有sug没有这些值之一。

通过这种方式，我得到了其中它其中一个枚举值的sug节点：

SELECT XMLSERIALIZE(XMLQUERY ('//xmlList/XMLEntity/sug[.="ACHER"]' passing 
KTOVET ) as char large object) as XXX ,

XMLSERIALIZE(XMLQUERY ('//xmlList/XMLEntity/sug[.="DOA"]' passing 
KTOVET ) as char large object) as YYY   

FROM "TABLE"

我希望{<1}}个节点的值不是其中一个枚举值。可能？如何获得其值为＃34; ACHER＆＃34;？

的sug节点

Answer 1

passing KTOVET ) as char large object) as XXX

FROM "TABLE"
