SQL Server2014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SQL或编程。我一直在阅读可用的在线文档和教程，以便在SSDT / SSIS中设置一个For循环，循环遍历文件夹中的一系列平面文件，并为每个具有相同名称的文件创建一个DB对象。

循环有效，但为OLE DB目标管理器设置连接字符串除外。我的服务器名为＆＃39; OLEGS_LAPTOP＆＃39;使用名为“足球数据”的数据库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;"

此处，@[User::FileFound]表示在平面文件连接管理器中设置的变量，用于循环浏览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，出现以下错误：

Answer 1

看起来好像是字符串＆＃34; OLE DB Destination＆＃34;进入table\view映射（第一个屏幕截图），[dbo].[OLE DB Destination]作为表名出现。也许您已在OpenRowset属性窗口的OLE DB Destination属性中用此字符串替换了表名（第二个屏幕截图）。

稍后编辑

为了能够从变量获取表名（假设您有这样的变量并为其分配了表名），您需要将OLE DB Destination的{​​{1}}属性更改为AccessMode并在OpenRowset From Variable属性中指定变量名称（参见下图）
