谁能帮帮我

推荐答案

使用:

declare @x xml='<Education>

          <School ID="1">
          <Degree>test</Degree>
          <Description>desc1</Description>
          <Institution>kec</Institution>
          </School>

          <School ID="2">
          <Degree>test2</Degree>
          <Description>desc2</Description>
          <Institution>kec2</Institution>
             </School>

      </Education>'


select t.s.value('@ID', 'int') [schoolid]
    , t.s.value('Degree[1]', 'nvarchar(20)') [degree]
    , t.s.value('Description[1]', 'nvarchar(20)') [desc]
    , t.s.value('Institution[1]', 'nvarchar(20)') [instituion]
from @x.nodes('Education/School') t(s)

输出:

schoolid    degree               desc                 instituion
----------- -------------------- -------------------- --------------------
1           test                 desc1                kec
2           test2                desc2                kec2
