适用于 SQLServer2014 的 SSDT/SSIS 中动态 OLE DB 目标的连接字符串

Question

我是 SQL Server 的新手，但不是一般的 SQL 或编程。我一直在阅读可用于在 SSDT/SSIS 中设置 For each 循环的在线文档和教程，该循环遍历文件夹中的一系列平面文件，并为每个文件创建一个同名的 DB 对象。

循环工作，除了为 OLE DB 目标管理器设置连接字符串。我的服务器名为“OLEGS_LAPTOP”，数据库名为“足球数据”，我正在使用以下连接字符串：

"Provider=SQLNCLI11.0;Server=OLEGS_LAPTOP;Source=(local);Initial Catalog="+ @[User::FileFound] + "Football Data"+";Integrated Security=SSPI;Auto Translate=False;"

这里，@[User::FileFound] 代表在平面文件连接管理器中设置的变量，用于循环访问我选择的本地文件夹中的文件。当我尝试将此连接字符串用于 OLE DB 对象时，我收到以下错误：

谁能告诉我我需要在字符串中进行哪些更改才能获得所需的结果？

谢谢

到目前为止给出的进一步答案/支持：

我现在收到的错误信息是：

Answer 1

看起来字符串“OLE DB Destination”以某种方式进入了table\view 映射（第一个屏幕截图），而[dbo].[OLE DB Destination] 作为表名出现了。也许您已经在OLE DB Destination 属性窗口的OpenRowset 属性中用这个字符串替换了表名（第二个屏幕截图）。

稍后编辑

为了能够从变量中获取表名（假设您有这样的变量并分配了表名），您需要将OLE DB Destination 的AccessMode 属性更改为OpenRowset From Variable 并指定变量名在OpenRowsetVariable 属性中（见下图）
