Sql server 在具有多个子查询的SQL Server 2008中被忽略的顺序

Sql server 在具有多个子查询的SQL Server 2008中被忽略的顺序,sql-server,sql-server-2008,sql-order-by,Sql Server,Sql Server 2008,Sql Order By,我有一份报告返回了一份患者就诊的列表，但就诊顺序完全混乱。访问列表在子查询中获得，如下所示： INNER JOIN (SELECT subject_id, A.id [VisitID], A.visit_schedule_id [VisitScheduleID], B.client_visit_descripti

我有一份报告返回了一份患者就诊的列表，但就诊顺序完全混乱。访问列表在子查询中获得，如下所示：

INNER JOIN (SELECT subject_id,
                               A.id [VisitID],
                               A.visit_schedule_id [VisitScheduleID],
                               B.client_visit_description [Visit],
                               visit_date_local [Visit Date],
                               call_date [Call Date]
                FROM tbl_visit A
                INNER JOIN tbl_visit_schedule B ON B.id = A.visit_schedule_id) F

有一个内部查询，它使用这个“F”块获取相关值以显示给最终用户，如下所示：

SELECT TOP 9999999999
           A.[name] [Country Name], 
           B.[site_number] [Site Number], 
           D.[investigator_name] [Investigator Name], 
           C.[spid] [Patient Number], 
           E.[YOB] [Year of Birth], 
           F.[Visit] [Visit], 
           CONVERT(NVARCHAR, F.[Visit Date], 120) [Visit Date],
           ISNULL(pl.[Pack(s) Assigned], 'N/A') [Kit Assigned],
           H.[Confirmation (doc)]
    FROM   (

最后还有一个外部选择，向用户显示：

SELECT DISTINCT
   [Country Name], 
   [Investigator Name], 
   [Patient Number], 
   [Year of Birth], 
   --[Visit], 
   [Visit Date],
   [Kit Assigned],
   [Confirmation (doc)]
FROM   (

我有一个内部select语句的ORDER BY，如下所示：

ORDER BY CAST(F.[Visit Date] AS DATE) asc, F.[Call Date] asc

问题是，当我显示所有内容时（'Visit'没有注释掉），SQL会以非顺序的方式返回结果，即使最后是order by。然而，如果我对这次访问进行评论，结果就开始有序了

我不确定这一专栏对导致order by失败的报告的其余部分有什么意义，还有其他人对此有任何线索吗

要按特定顺序获得输出，需要在“rawquery”别名后添加order by。因为现在查询没有orderby，所以无法知道结果的顺序

您在外部查询中按下单日期下单。请按F下单。访问日期在您的sub中query@Ganesh_Devlekar不幸的是，我无法将其放在外部查询中，因为我在一个框架内实现了这个功能，该框架做了一些特定的事情，从而排除了在外部查询中使用order by。@Steve我尝试过以这种方式对子查询进行排序，并且虽然子查询将以有序的方式返回结果，但最终结果仍然是无序的。尝试将子查询的结果表别名并按顺序排列如何？我必须问……选择子查询中前100亿行有什么意义？您的表是否真的有比这更多的行，并且您希望确保它们是有序的？你意识到像这样对子查询进行排序真的毫无意义吗？前100亿行是我在别处读到的一个hack（），它应该有助于克服在视图中按顺序排序的限制。我知道这是一种糟糕的编码实践，但我真的很想让订购工作正常进行。由于将orderby添加到外部查询对我来说是不可能的，因此我必须接受无法进行排序。谢谢大家的帮助。正如你所说，这是一个黑客行为。它也不再工作了。更糟糕的是，如果查询中的视图使用了相同的方法，那么它就永远不会起作用。哪一个订单可以接受？
