我有一份报告会返回患者的访问列表，但是访问顺序是完全混乱的。访问列表是在子查询中获得的，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
有一个内部查询使用这个“F”块来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 (
最后有一个外部选择显示给用户：
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
问题在于，当我显示所有内容时（“访问”未被注释掉），SQL会以无序方式返回结果，即使最后的顺序也是如此。如果我评论访问，但结果开始有序。
我不确定这个特定专栏对导致失败的报告的其余部分有何意义，其他人是否有任何关于此事的线索？
更新：这是整个查询：

要按特定顺序获取输出，您需要在“rawquery”别名之后添加订单。由于它现在位于您的查询没有顺序，因此您无法知道结果的顺序。
