Question

我有一个存储过程，其中我有一个表格如下：

CREATE TEMPORARY TABLE tt_ASSET_DETAILS

 (
      SiteGroup VARCHAR(30),
      SiteNumber VARCHAR(50),
      AssetCategory VARCHAR(30),
      Address VARCHAR(50),
      AssetName VARCHAR(50)
   );

我想从以下XML中将数据插入此表：

<ManageAsset>
  <Asset>
    <SiteGroup>Chicago</SiteGroup>
    <SiteNumber>4524</SiteNumber>
    <AssetCategory>Passenger Cars</AssetCategory>
    <Address>Address 1</Address>
    <AssetNumber>Tango</AssetNumber>
  </Asset>
  <Asset>
    <SiteGroup>Cincinnati</SiteGroup>
    <SiteNumber>5360</SiteNumber>
    <AssetCategory>Passenger Cars</AssetCategory>
    <Address>Address 2</Address>
    <AssetNumber>Mango</AssetNumber>
  </Asset>
</ManageAsset>

现在，我希望将节点集<Asset> </Asset>之间的数据作为第一行插入，将另一组<Asset> </Asset>作为第二行插入。

为此我使用了以下代码，它将<Asset> </Asset>的两个集合插入到表的一行中，

INSERT INTO tt_ASSET_DETAILS(SiteGroup,SiteNumber,AssetCategory,Address,AssetName)
   SELECT SiteGroup,SiteNumber,AssetCategory,Address,AssetNumber
   FROM
    (select ExtractValue(AssetsXML,'//ManageAsset/Asset/SiteGroup') as SiteGroup,
            ExtractValue(AssetsXML,'//ManageAsset/Asset/SiteNumber') as SiteNumber,
            ExtractValue(AssetsXML,'//ManageAsset/Asset/AssetCategory') as AssetCategory,
            ExtractValue(AssetsXML,'//ManageAsset/Asset/Address') as Address,
            ExtractValue(AssetsXML,'//ManageAsset/Asset/AssetNumber') as AssetNumber) XM;

有人，请帮我纠正我的代码，以便达到我所需的结果!!!

我已经得到了我的问题的答案。使用WHILE循环满足需要！

    SET @COUNT = (SELECT EXTRACTVALUE(AssetsXML,'COUNT(/ManageAsset/Asset)'));
    SET @I = 1;
    WHILE (@I <= @COUNT) DO
    INSERT INTO tt_ASSET_DETAILS(SiteGroup,SiteNumber,AssetCategory,Address,AssetName)
    SELECT  ExtractValue(AssetsXML,CONCAT('/ManageAsset/Asset[',@I,']/SiteGroup')),
            ExtractValue(AssetsXML,CONCAT('/ManageAsset/Asset[',@I,']/SiteNumber')),
            ExtractValue(AssetsXML,CONCAT('/ManageAsset/Asset[',@I,']/AssetCategory')),
            ExtractValue(AssetsXML,CONCAT('/ManageAsset/Asset[',@I,']/Address')),
            ExtractValue(AssetsXML,CONCAT('/ManageAsset/Asset[',@I,']/AssetNumber'));
    SET @I = @I + 1;
  END WHILE;

现在，如果我将表中的数据作为SELECT * FROM tt_ASSET_DETAILS;查询，我将把数据插入到不同行的表中！

使用ExtractValue（）函数在MySQL中的表中插入XML数据
