使用 XML 批量插入

Question

我无法编写用于批量插入表的存储过程。

我想将<ObjectID> 列表插入[tbl_ReleaseHistory] 保持<FeatureID> 为空。

同时将<FeatureID> 插入同一个表时<ObjectID> 应保持为空。

我只能从传递给虚拟执行的 xml 中插入第一个 <ObjectID> 和 <FeatureID> 即 2218 和 67。

现在如何迭代<objectID> 的列表以进行插入？

那么还有其他方法吗？

如何使用 XML 执行批量插入？

不是 100% 确定我理解你想要做什么......但假设这是你的 XML 文件：

DECLARE @Input XML 
SET @Input = '<Root>
                 <ApplicationEntity>
                    <Id>0</Id>
                    <versionId>0</versionId>
                    <Versions>
                       <Version>
                          <Application>1111</Application>
                          <Version>11.11.123.123</Version>
                          <VersionMajor>11</VersionMajor>
                          <VersionMinor>11</VersionMinor>
                          <VersionBuild>123</VersionBuild>
                          <VersionRevision>123</VersionRevision>
                          <VersionFeatureIdList>
                             <FeatureID>67</FeatureID>
                             <FeatureID>68</FeatureID>
                             <FeatureID>69</FeatureID>
                          </VersionFeatureIdList>
                          <VersionObjectIdList>
                             <ObjectID>2218</ObjectID>
                             <ObjectID>2219</ObjectID>
                             <ObjectID>2220</ObjectID>
                             <ObjectID>2221</ObjectID>
                             <ObjectID>2222</ObjectID>
                             <ObjectID>2223</ObjectID>
                             <ObjectID>2224</ObjectID>
                             <ObjectID>2225</ObjectID>
                             <ObjectID>2226</ObjectID>
                             <ObjectID>2227</ObjectID>
                             <ObjectID>2228</ObjectID>
                             <ObjectID>2229</ObjectID>
                          </VersionObjectIdList>
                          .... (more stuff - not relevant here) ....
                       </Version>
                    </Versions>   
                 </ApplicationEntity>
              </Root>'

您可以使用 SQL Server 2005 XQuery 功能轻松选择所有 ObjectID 值（比旧的 openxml 更容易使用）：

SELECT
    V.VOI.value('(.)[1]', 'int')
FROM
    @Input.nodes('/Root/ApplicationEntity/Versions/Version/VersionObjectIdList/ObjectID') V(VOI)

或功能 ID 列表：

SELECT
    F.FID.value('(.)[1]', 'int')
FROM
    @Input.nodes('/Root/ApplicationEntity/Versions/Version/VersionFeatureIdList/FeatureID') F(FID)

现在你想用这些值做什么？

更新：好的，所以要插入值，请使用以下语句：

INSERT INTO dbo.tbl_ReleaseHistory(RL_VersionId, RL_ObjectId, RL_FeatureId) 
   SELECT
        V.VOI.value('(.)[1]', 'int'),
        (some value for RL_ObjectId),
        (some value for RL_FeatureId)
   FROM
       @Input.nodes('/Root/ApplicationEntity/Versions/Version/VersionObjectIdList/ObjectID') V(VOI)

对于功能也是如此。
