asp.net-mvc - MVC ELMAH 和 SQL Azure

Question

背景故事:我们主要使用 AWS 来处理所有事情(托管、数据库、通知等)。现在，我正在考虑将数据库端迁移到 SQL Azure，因为我们在 AWS RDS 上收到了疯狂的账单。因此，我尝试做的就是在 SQL Azure 中创建一个数据库并更新连接字符串以指向新数据库。过去，ELMAH(此具体实现:https://github.com/alexanderbeletsky/elmah.mvc)过去工作得完美无缺。

现状:我刚刚在 SQL Azure 中创建了一个新的数据库，并立即注意到关键的差异，即不支持:

在[主键]、非聚集键等上

我很好地迁移了我的数据库(目前)，但是当我将 ELMAH 的更新脚本应用到数据库并尝试进入该工具时，我收到错误!

我以某种方式确信这是一个数据库问题，因为如果我删除: <errorLog type="Elmah.SqlErrorLog, Elmah" connectionStringName="DefaultConnection"/>基本上默认 ELMAH 在本地存储所有内容，我可以访问 ELMAH。

有人让 ELMAH 在 SQL Azure 上工作吗？您能给我生成表和存储过程的 SQL 脚本吗？

这是我在 SQl Azure 上用于 ELMAH DB 的数据库脚本:

SQL Azure 是 SQL 的特殊版本，它不支持某些功能。

您是否使用 SQL Azure 迁移向导来迁移数据库？
