I have created user defined data types in my project. 我在项目中创建了用户定义的数据类型。 Now I am going to deploy my project on Windwos Azure. 现在我要在Windwos Azure上部署我的项目。

I have defined user defined CLR data types in my sql server 2008 database. 我在我的sql server 2008数据库中定义了用户定义的CLR数据类型。 As much as I have read about user-defined CLR data types, these are not supported in Windows Azure SQL Database. 尽管我已经阅读过有关用户定义的CLR数据类型的信息，但Windows Azure SQL数据库中不支持这些类型。

Is there any alternative for databases with user-defined CLR datatypes when migrating to Windows Azure SQL Database? 迁移到Windows Azure SQL数据库时，是否有任何替代数据库具有用户定义的CLR数据类型？

Alternatives: 备择方案：

1) Change the application to use only data types supported by Windows Azure SQL Database. 1）将应用程序更改为仅使用Windows Azure SQL数据库支持的数据类型。 Downside: requires code and database changes. 缺点：需要更改代码和数据库。 Upside: hosted, highly available service. 好处：托管，高可用性服务。

2) Use an on-premises or third-party SQL Server. 2）使用内部部署或第三方SQL Server。 Downside: you have to host SQL Server yourself or pay someone to host it; 缺点：你必须自己托管SQL Server或付钱给某人托管它; latency may be an issue; 延迟可能是一个问题; availability and management is your concern. 可用性和管理是您关注的问题。 Upside: full SQL Server compatibility. 好处：完全兼容SQL Server。

3) Host SQL Server in Windows Azure Virtual Machines using VM images published by Microsoft. 3）使用Microsoft发布的VM映像在Windows Azure虚拟机中托管SQL Server 。 Downside: management is your concern; 缺点：管理层是您关注的问题; high availability requires additional configuration . 高可用性需要额外配置。 Upside: full SQL Server compatibility; 好处：完全兼容SQL Server; low latency; 低延迟; highly available infrastructure. 高度可用的基础设
