如何测试数据库是否托管在SQL Azure上?

问题描述

是否可以测试数据库是否托管在SQL Azure上?我正在查看EF6的SqlAzureExecutionStrategy，仅在数据库实际上是SQL Azure数据库的情况下才想应用.

Is it possible to test whether a database is hosted on SQL Azure? I am looking at SqlAzureExecutionStrategy for EF6 and only want to apply if the database is actually SQL Azure database.

当前，我正在测试App是否在Azure中运行.但是，我们正在考虑允许客户端自己托管数据库，从而希望通过某种方式来识别数据库是SQL Server还是Azure SQL.

Currently I am testing if App is running within Azure. However we are looking at allowing clients to host DB themselves so would like some way to identify if DB is a SQL Server or Azure SQL.

假设EF不会知道，因为它正在隐藏实施细节.

Assume EF won't know as it is hiding the implementation details.

我想可能只有一个配置设置.只是想知道这在技术上是否可行.

Could just have a config setting I guess. Just wondered if it was technically possible.

推荐答案

SELECT CASE ServerProperty('EngineEdition')
         WHEN 1 THEN 'Personal'
         WHEN 2 THEN 'Standard'
         WHEN 3 THEN 'Enterprise'
         WHEN 4 THEN 'Express'
         WHEN 5 THEN 'Azure'
         ELSE 'Unknown'
       END
