将 XML 数据迁移到 Microsoft SQL Server 2016

Question

我想将 XML 文件中的数据迁移到 MS SQL Server 2016

我的 Table 文件如下所示：

[propertyid], [type], [object], [keyname], [keyvalue]

table 中的数据将从 XML 映射而来，如下所示：

1, community, Private Community, name, Private Community   
2, community, Private Community, communityname, Private Community  
3, community, Private Community, server, chip.xyz.com:423132  
4, community, Private Community, windowtitle, Private Community  
5, community, Private Community, websiteurl, http://something

XML 文件如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<doc>
<object type="community">
<name>
<![CDATA[Private Community]]>
</name>
<communityname>
<![CDATA[Private Community]]>
</communityname>
<server>
<![CDATA[chip.xyz.com:423132]]>
</server>
<windowtitle>
<![CDATA[Private Community]]>
</windowtitle>
<websiteurl>
<![CDATA[http://something]]>
</websiteurl>
</object>
</doc>

有什么方法可以通过脚本或任何方式来完成，因为上面提到的 XML 只是我正在使用并有很多记录的大 XML 的一部分

这样试试：

DECLARE @xml XML=
'<?xml version="1.0" encoding="UTF-8"?>
<doc>
  <object type="community">
    <name>
Private Community
</name>
    <communityname>
Private Community
</communityname>
    <server>
chip.xyz.com:423132
</server>
    <windowtitle>
Private Community
</windowtitle>
    <websiteurl>
http://something
</websiteurl>
  </object>
</doc>';

我替换了换行符和 trim 字符串，希望这符合您的需要我不知道的是：如果有更多数据，结构如何。我的查询以 doc 为根，以 doc/name 为 "type"，所有节点名称为 "keyname".

使用 "INTO MyNewlyCreatedTable" 可以即时创建具有所需结构的 table。如果你已经有了你的 table，你就把这行拿出来，在上面写一个合适的 INSERT INTO MyTable(colName1,colName2,...)，然后是 SELECT ...

SELECT ROW_NUMBER() OVER(ORDER BY (SELECT NULL)) AS propertyid
      ,LTRIM(RTRIM(REPLACE(REPLACE(Doc.value('(object/@type)[1]','varchar(max)'),CHAR(13),''),CHAR(10),''))) AS [type]
      ,LTRIM(RTRIM(REPLACE(REPLACE(Doc.value('(object/name)[1]','varchar(max)'),CHAR(13),''),CHAR(10),''))) AS [object]
      ,LTRIM(RTRIM(REPLACE(REPLACE(Nod.value('local-name(.)','varchar(max)'),CHAR(13),''),CHAR(10),''))) AS keyname
      ,LTRIM(RTRIM(REPLACE(REPLACE(Nod.value('.','varchar(max)'),CHAR(13),''),CHAR(10),''))) AS keyvalue
INTO MyNewlyCreatedTable
FROM @xml.nodes('/doc') AS A(Doc) 
CROSS APPLY Doc.nodes('object/*') AS B(Nod)

这是新建的内容table

SELECT * FROM MyNewlyCreatedTable;

+------------+-----------+-------------------+---------------+---------------------+
| propertyid | type      | object            | keyname       | keyvalue            |
+------------+-----------+-------------------+---------------+---------------------+
| 1          | community | Private Community | name          | Private Community   |
+------------+-----------+-------------------+---------------+---------------------+
| 2          | community | Private Community | communityname | Private Community   |
+------------+-----------+-------------------+---------------+---------------------+
| 3          | community | Private Community | server        | chip.xyz.com:423132 |
+------------+-----------+-------------------+---------------+---------------------+
| 4          | community | Private Community | windowtitle   | Private Community   |
+------------+-----------+-------------------+---------------+---------------------+
| 5          | community | Private Community | websiteurl    | http://something    |
+------------+-----------+-------------------+---------------+---------------------+

仅供测试

--CleanUp
DROP TABLE MyNewlyCreatedTable;
