複製和輸出序列號

Question

每個患者應該有獨特的randomID這些randomID的應該是序列順序，所以我應該 帶回（複製RandomID）和（出序列RandomID的）

這裏是我的查詢

declare @valueCheck table 
(RowNumber Int Identity 
,PatientID varchar(25) 
,RandomID varchar(25)) 

insert into @ValueCheck 
(PatientID, RandomID) 

select 
PatientID 
, RandomID 

From dbo.CurrentData 

where QuestionID= 200 
order by patientid, RandomID 

如果我申請這個條件，我會得到（亂序RandomID）

Select s1.PatientID, s1. RandomID as OutOFSequence 
From @ValueCheck s1 
Left Join @ValueCheck s2 
On s1.RandomID = s2.RandomID – 1 
Where s2.RandomID is Null 

，如果我申請這個，我會得到（複製蘭特奧米德）

​​

我想是的，我想這既帶來了條件一起

Answer 1

你爲什麼不辦一個聯合查詢的表。

Select s1.PatientID, s1. RandomID, 'OutOFSequence' 
From @ValueCheck s1 
Left Join @ValueCheck s2 
On s1.RandomID = s2.RandomID – 1 
Where s2.RandomID is Null 
union all 
select PatientID, RandomID, 'Duplicate' from @ValueCheck 
where RandomID in 
(Select RandomID 
From @ValueCheck 
Group by RandomID 
Having Count(RandomID) > 1)
