Microsoft 同步框架 'Expected column' 错误

Question

过去几个月我一直在使用 Microsoft Sync Framework，没有任何问题，我向数据库添加了新列，本地数据库和服务器数据库之间的同步没有任何问题。最近，我向 tablet 添加了一些新列，但在同步特定 table:

时出现错误

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 table 从服务器下载到我的本地数据库。这一直有效，但现在我突然收到此错误。我的本地数据库和服务器数据库的 table MyTable 中都有 foo 列。此错误背后的原因可能是什么？

Answer 1

我找不到任何解决方案，所以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。问题似乎出在数据库的迁移历史中。

Answer 2

当您提供 table 时，会创建相应的 UDF (TVF) 来表示 table。当您运行迁移时，这可能与基础 table 不同步。
