Question

尝试在这段时间内获得与每个PatientID相关的最早日期。

当前SQL在患者的时间段内返回多次访问/文档我需要在日期范围内仅显示与特定提供者绑定的患者的最早日期。

PatientID的多个日期

    USE EHR 
    SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED
    DECLARE @PROV NVARCHAR (255) ='KCOOPER0'
    DECLARE @START_DATE DATETIME = '2017-09-18 00:00:00.000'    
    DECLARE @END_DATE DATETIME = '2017-12-17 23:59:59.999'    
    --DECLARE @START_DATE DATETIME = '2017-10-02 00:00:00.000'    
    --DECLARE @END_DATE DATETIME = '2017-12-31 23:59:59.999'    

    SELECT DISTINCT 
                PS.ID AS AppointmentID
                , CL.Code AS PatientID
--              , SU.NameFirst AS PROVFNAME

    INNER JOIN ContactsList CL WITH(NOLOCK) ON PS.PatientID=CL.ReferenceID
    AND CL.Relation = 0
       AND PS.ScheduledDateTime BETWEEN @START_DATE AND @END_DATE
    INNER JOIN SystemUsers SU WITH(NOLOCK) ON PS.InterfaceCode=SU.InterfaceCode AND SU.Status='1'

              ,ED.PATIENTSCHEDULEID
              ,EDE.CreatedOn

              AND ED.IsSignedOff ='TRUE'
              INNER JOIN EMRDocumentExport EDE ON ED.ID=EDE.DocumentId
              AND EDE.LabCompanyName = 'FollowMyHealth_CCDA'
              ) CDA ON PS.ID=CDA.PatientScheduleId
    WHERE --CL.Code = @PatientID
              su.RegisteredProvider =1
              AND SU.UserID =@PROV 
       ORDER BY CL.Code, CDA.CreatedOn

Answer 1

这是一般的想法。您可以填写详细信息。

"AustrittDatum": [
  "2018-01-31+01:00",
  null
],

Answer 2

无连接选项，使用窗口函数和公用表表达式或坚持使用子选择。

使用CTE：

with mindates as (
    select field1, field2, ..., 
        AppointmentDT,
        min(AppointmentDT) OVER (PARTITION BY PatientID) minptAppointmentDT
    from table
)

select field1, field2, ... , AppointmentDT from mindate_table
where AppointmentDT = minptAppointmentDT

使用subselect：

select field1, field2, ... , AppointmentDT from 
    (select field1, field2, ..., 
    AppointmentDT, 
    min(AppointmentDT) OVER (PARTITION BY PatientID) minptAppointmentDT
    from table) mindates
where AppointmentDT = minptAppointmentDT
