我在 Visual Studio 2008 中使用 SSIS.我有很多 XML 文件需要处理并放入现有的数据库结构 (SQL Server 2005) 中.这是我第一次尝试使用 SSIS 并且有点卡住了.我找到了 XML 数据流任务,为它分配了一个测试 xml 文件及其关联的 XSD,并将一个节点映射到数据库表.我的问题是,如何将许多 xsd 节点与许多表相关联?当然我不必为每个表设置一个 XML 源?
I am using SSIS in Visual Studio 2008. I have many XML files that I need to process and place into an existing DB structure (SQL Server 2005). This is my first attempt at using SSIS and am a little stuck. I have found the XML Data Flow task, assigned it a test xml file and it's associated XSD, and mapped one node to a Database Table. My question is, how do I associate many xsd nodes with many tables? Surely I don't have to set up an XML source for each table?
这是一个可能的选项,它演示了如何将具有相同定义的多个 XML 文件加载到 SQL Server 表中.该示例使用 SQL Server 2008 R2
和 SSIS 2008 R2
.此处显示的示例在 XML Source
组件的帮助下使用 SSIS Data Flow Task
将三个 XML 文件加载到 SQL 表中.
Here is a possible option which demonstrates how to load multiple XML files having same definition into an SQL Server table. The example uses SQL Server 2008 R2
and SSIS 2008 R2
. The example shown here loads three XML files into an SQL table using SSIS Data Flow Task
with the help of XML Source
component.
分步过程:
dbo.Items
的表.Items.xsd
的 XSD 文件.Items_1.xml
、Items_2.xml
和 Items_3.xml
tempxml 使用 XML 文件 部分下提供的内容.FileExtension
、FilePath
和 FolderPath
,如截图 #1.SQLServer
的 OLE DB 连接以连接到 SQL Server 实例,如屏幕截图 #2 所示.Control Flow
选项卡上,在 Foreach 循环容器中放置一个 Foreach 循环容器
和一个 Data Flow Task
,如屏幕截图所示#3.Foreach Loop 容器
,如屏幕截图 #4 和 #5 所示.Data Flow Task
以导航到Data Flow
选项卡.放置一个 XML Source
组件和一个 OLE DB Destination
,如屏幕截图 #6 所示.XML 源
,如屏幕截图 #7 和 #8 所示.XML 文件路径将从变量 FilePath 中检索.此变量将由 Foreach 循环容器
填充.OLE DB 目标
,如屏幕截图 #9 和 #10 所示.dbo.Items
中的数据现在包含存在于三个 XML 文件中的数据.dbo.Items
using the script given under SQL Scripts section.Items.xsd
in the folder path C: empxsd using the content provided under XSD File section.Items_1.xml
, Items_2.xml
and Items_3.xml
in the folder path C: empxml using the content provided under XML Files section.FileExtension
, FilePath
and FolderPath
as shown in screenshot #1.SQLServer
to connect to the SQL Server Instance as shown in screenshot #2.Control Flow
tab, place a Foreach loop container
and a Data Flow Task
within the Foreach loop container as shown in screenshot #3.Foreach Loop container
as shown in screenshots #4 and #5.Data Flow Task
to navigate to the Data Flow
tab. Place an XML Source
component and an OLE DB Destination
as shown in screenshot #6.XML Source
as shown in screenshot #7 and #8. The XML file path will be retrieved from the variable FilePath. This variable will be populated by the Foreach Loop container
.OLE DB Destination
as shown in screenshots #9 and #10.dbo.Items
now contains the data present in three XML files.希望有所帮助.
SQL 脚本:
CREATE TABLE [dbo].[Items](
[Id] [int] IDENTITY(1,1) NOT NULL,
[ItemNumber] [nvarchar](50) NOT NULL,
[ItemName] [nvarchar](60) NOT NULL,
[Price] [numeric](18, 2) NOT NULL,
CONSTRAINT [PK_Items] PRIMARY KEY CLUSTERED ([Id] ASC)) ON [PRIMARY]
