重复和无序号

Question

每个患者都应该有唯一的 randomID，这些 randomID 应该是按顺序排列的，所以我应该 带回 (Duplicate RandomID) 和 (Out of Sequence RandomID)

这是我的查询

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 

如果我应用这个条件，我会得到（乱序的 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

如果我应用这个，我会得到 (Duplicate RandomID)

select * from @ValueCheck
where RandomID in 
(Select RandomID
From @ValueCheck
Group by RandomID
Having Count(RandomID) > 1)

我想要的是，我想要一个将两种条件结合在一起的表格

Answer 1

你为什么不做一个联合查询。

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)
