Question

我在过去几个月里一直使用Microsoft Sync Framework没有问题，我在数据库中添加了新列，本地数据库与服务器数据库之间的同步没有问题。最近，我在平板电脑上添加了一些新列，并在同步特定表时遇到错误：

Expected column 'foo' was not found on the DataTable to be applied to the destination table 'MyTable'.
Parameter name: dataTable
System.ArgumentException: Expected column 'foo' was not found on the DataTable to be applied to the destination table 'MyTable'.

我正在尝试将整个表从服务器下载到我的本地数据库。这总是有效但现在我突然得到这个错误。我的本地数据库和服务器数据库中的表foo中都有列MyTable。这个错误背后的原因是什么？

Answer 1

我无法找到任何解决方案，因此我最终创建了一个新数据库，运行迁移并从旧数据库导入所有数据。问题似乎出现在数据库的迁移历史中。

Answer 2

配置表时，会创建相应的UDF（TVF）来表示表。运行迁移时，这可能与基表不同步。

Microsoft Sync Framework“预期列”错误
