SubSonic 3.0.0.3 | SimpleRepository - OrderByDescending和。首先（）

此代码工作正常在SQL Express 2008：SubSonic 3.0.0.3 | SimpleRepository - OrderByDescending和。首先（）

return _repository.GetInstructions() 
     .Where(x => x.PublishedDate != null) 
     .OrderByDescending(x => x.PublishedDate) 
     .First();

但使用SQL Server 2000上运行时，它打破。这里是错误。如果有人想看到它，我会发布痕迹。

FailedSystem.Data.SqlClient.SqlException: Line 1: Incorrect syntax near '('.

这里的痕迹：

你能发布这个查询生成的sql以及堆栈跟踪吗？ – 2009-08-12 18:54:15

这是一个问题 - 我发布了一个决议在这里：http://stackoverflow.com/questions/1397933/subsonic3-method-firstordefault-throws-exception-with-sql-server-2000/3466302#3466302 – DaveHogan 2010-09-21 21:02:46

我不认为亚音速完全支持MS SQL 2000 我自己的调查结果表明。首先（）genarates TOP（1）
对于MS SQL 2000应该是TOP 1没有括号

这是真的，我有刚刚遇到了这个bug，我通过你的回答将它解开了。现在我使用SimpleRepository.Single而不是All和First之后 – Tom 2013-02-25 18:30:53

亚音速文档（http://subsonicproject.com/docs/Supported_Databases）说，它支持的“SQL Server（200-2008）”，因此，这意味着它可能是一个错误。我想你应该把它作为一个问题提交给SubSonic的github网站。
