Question

我有两个问题。第一个检查任何更改的列（FirstName，LastName，Phone）基于另一列是相同的（EncounterID）：

 select FacilityCode, AdmitDate,
  sum(case when NumFirstName <> 1 then 0 else 1 end) as DifferentFirstNames,
  sum(case when NumLastName <> 1 then 0 else 1 end) as DifferentLastNames,
  sum(case when NumPhone <> 1 then 0 else 1 end) as DifferentPhone ,
  'Non-Defect' Label  

 from (select EncounterId, FacilityCode, AdmitDate, count(*) as Num,
  count(distinct left(FirstName,4)) as NumFirstName,
  count(distinct LastName) as NumLastName,
  count(distinct Phone) as NumPhone,

 from [BINextGen].[dbo].[tbFCCDefectReport]

 group by EncounterId, facilitycode, AdmitDate
 ) e
 group by FacilityCode, AdmitDate;

第二个检查列不变的所有实例：

 select FacilityCode, AdmitDate,
  sum(case when NumFirstName <> 1 then 1 else 0 end) as DifferentFirstNames,
  sum(case when NumLastName <> 1 then 1 else 0 end) as DifferentLastNames,
  sum(case when NumPhone <> 1 then 1 else 0 end) as DifferentPhone ,
  'Non-Defect' Label  

 from (select EncounterId, FacilityCode, AdmitDate, count(*) as Num,
  count(distinct left(FirstName,4)) as NumFirstName,
  count(distinct LastName) as NumLastName,
  count(distinct Phone) as NumPhone,

 from [BINextGen].[dbo].[tbFCCDefectReport]

 group by EncounterId, facilitycode, AdmitDate
 ) e
 group by FacilityCode, AdmitDate;

我能够操纵输出以显示每个设施的'缺陷率'并允许日期（EncounterID是患者文件的标识符，我试图查看文件中的任何数据是否随时间而变化）。现在我想看看有多少EncounterIDs有任何列更改。见下面的例子：

FacilityCode    AdmitDate    EncounterID    FirstName    LastName    Phone 
SMAL            5/15/15      A01342         Justin       Kelley      5551212
SMAL            5/15/15      A01342         Justin       Kelly       5551212
SMAL            5/15/15      B53421         John         Doe         7771234
SMAL            5/15/15      B53421         John         Doe         7771234

当前输出：

FacilityCode    DifferentFirstNames    DifferentLastNames    DifferentPhone    Label
SMAL            2                      1                     2                 Non-Defect
SMAL            0                      1                     0                 Defect

期望的输出：

FacilityCode    Count    Label
SMAL            1        Defect
SMAL            1        Non-Defect

任何帮助都将不胜感激 - 谢谢。

Answer 1

case
WHen sum(case when NumFirstName <> 1 then 0 else 1 end) >= 1 Then  1 
 WHEN  sum(case when NumLastName <> 1 then 0 else 1 end) >= 1 Then  1 
 WHEN sum(case when NumPhone <> 1 then 0 else 1 end) >= 1 Then  1 
else  0 end as 'Count'

您只需将参数捆绑到case语句中即可。希望能帮助到你。您的代码示例也是重复的，只是一个fyi
