SSIS 错误：源的外部列与数据源列不同步；如何删除外部列？

Question

查询应输出特定的项目列表，以及商店信息和经理信息等信息。使用光标浏览各种不同管理级别的列表，选择相关信息，然后通过电子邮件将查询返回的区域/区域/商店的内容发送给该人。

我的问题在于旅程的 SSIS 部分。虽然代码的行为就像它运行一样，但如果我单独运行 Itemdata.dtsx（以便查看错误），它会抛出错误：

“警告：组件“Sources-ItemData”(1) 的外部列与数据源列不同步。需要从外部列中删除外部列“RM_Email”(49)。外部列“SM_Email”(46) 需要从外部列中删除。外部列“DM_Email”(43) 需要从外部列中删除。”

这导致 SQL Server Mngt Studio 说它运行了，但电子邮件的内容只是表头；没有数据，无论我做什么，表格标题都不会改变。

我已经从我的源代码（发布在下面）和它使用的表格中的任何提及中删除了这些列。我错过了什么？

Answer 1

重新检查源和目标之间以及组件之间的列分配。

通过将数据流组件的属性 ValidateExternalMetadata 设置为 False 来尝试一下。

也请查看this。

Answer 2

您最近似乎正在更改 OLEDB 源或其他类型的源。

因此，您必须删除 OLEDB Source 并重新创建一个新的。然后还要删除特定字段的映射，保存，再次返回映射并重新映射。比它应该工作正常。

Answer 3

而不是删除和重新创建：

1. 复制现有数据源。
2. 将其粘贴回数据流任务中。粘贴的数据源具有刷新的架构。您已保留任何可能保留的下游映射。您现在面临的维护最少。
3. 从旧数据源中删除连接器。
4. 用新数据源替换连接器。
5. 如有必要，在数据目标中维护映射。

Answer 4

我也有同样的问题，我的所有列名都相同，但仍然得到“'excelName' 的外部列与数据源列不同步。列 “mycolname” 需要要添加到外部列。 需要将列“F62”添加到外部列中。” 我也验证了很多次，但没有运气，即使我在 excel 公式中也将我的列标题与目标表匹配，并且一切似乎都是正确的。所以我手动一列一列检查，最后发现我用于我的文件连接最初的首字母大写 "Mycolname" ，作为我使用的文件（我曾经覆盖源文件），我只是粘贴了来自其他文件的数据，因为我的标题已更改。我再次更改了我的输入文件的标题并且它起作用了。

注意：使用 SSIS 时要小心……真的很危险。
