T-SQL 如何在不考虑输入参数的情况下拉取上一行

Question

我正在处理打印再入院患者就诊信息的报告。

T-SQL查询根据IIF语句（使用LEAD和LAG）打印重复访问，查看是否有访问在同一位患者就诊入院日期后的 30 天内 - 简单地说 1 表示是，0 表示否 (AS 'ReadmittedFilter')，并且当没有输入任何参数时，我可以按预期看到所有数据。查询如下：

,IIF(   (IIF(((xxUnitNumber.UnitNumber = LEAD(xxUnitNumber.UnitNumber) OVER (PARTITION BY xxUnitNumber.UnitNumber ORDER BY xxUnitNumber.UnitNumber, RAM.AccountNumber) 
        AND xxUnitNumber.UnitNumber = LAG(xxUnitNumber.UnitNumber) OVER (PARTITION BY xxUnitNumber.UnitNumber ORDER BY xxUnitNumber.UnitNumber, RAM.AccountNumber))
        AND ((DATEDIFF(DAY,LAG(RART.RegistrationTypeDischargeDateTime) OVER (PARTITION BY xxUnitNumber.UnitNumber ORDER BY xxUnitNumber.UnitNumber, RAM.AccountNumber),RAM.AdmitDateTime) BETWEEN 0 AND 30))),
        DATEDIFF(DAY,LAG(RART.RegistrationTypeDischargeDateTime) OVER (PARTITION BY xxUnitNumber.UnitNumber ORDER BY xxUnitNumber.UnitNumber, RAM.AccountNumber),RAM.AdmitDateTime),0) 

        = IIF(((xxUnitNumber.UnitNumber = LEAD(xxUnitNumber.UnitNumber) OVER (PARTITION BY xxUnitNumber.UnitNumber ORDER BY xxUnitNumber.UnitNumber, RAM.AccountNumber) 
        AND xxUnitNumber.UnitNumber = LAG(xxUnitNumber.UnitNumber) OVER (PARTITION BY xxUnitNumber.UnitNumber ORDER BY xxUnitNumber.UnitNumber, RAM.AccountNumber))
        AND ((DATEDIFF(DAY,LAG(RART.RegistrationTypeDischargeDateTime) OVER (PARTITION BY xxUnitNumber.UnitNumber ORDER BY xxUnitNumber.UnitNumber, RAM.AccountNumber),RAM.AdmitDateTime) BETWEEN 0 AND 30))),
        DATEDIFF(DAY,LAG(RART.RegistrationTypeDischargeDateTime) OVER (PARTITION BY xxUnitNumber.UnitNumber ORDER BY xxUnitNumber.UnitNumber, RAM.AccountNumber),RAM.AdmitDateTime), 0)) 

    AND (IIF(((xxUnitNumber.UnitNumber = LEAD(xxUnitNumber.UnitNumber) OVER (PARTITION BY xxUnitNumber.UnitNumber ORDER BY xxUnitNumber.UnitNumber, RAM.AccountNumber) 
    OR xxUnitNumber.UnitNumber = LAG(xxUnitNumber.UnitNumber) OVER (PARTITION BY xxUnitNumber.UnitNumber ORDER BY xxUnitNumber.UnitNumber, RAM.AccountNumber))
    AND ((DATEDIFF(DAY,LAG(RART.RegistrationTypeDischargeDateTime) OVER (PARTITION BY xxUnitNumber.UnitNumber ORDER BY xxUnitNumber.UnitNumber, RAM.AccountNumber),RAM.AdmitDateTime) BETWEEN 0 AND 30))),

DATEDIFF(DAY,LAG(RART.RegistrationTypeDischargeDateTime) OVER (PARTITION BY xxUnitNumber.UnitNumber ORDER BY xxUnitNumber.UnitNumber, RAM.AccountNumber),RAM.AdmitDateTime),
DATEDIFF(DAY,RART.RegistrationTypeDischargeDateTime, LEAD(RAM.AdmitDateTime) OVER (PARTITION BY xxUnitNumber.UnitNumber ORDER BY xxUnitNumber.UnitNumber, RAM.AccountNumber))) BETWEEN 0 AND 30),

1,0) AS 'ReadmittedFilter'

我正在插入所有数据 INTO #tblTempCalculations 然后我做

SELECT *  
FROM #tblTempCalculations 
WHERE #tblTempCalculations.ReadmittedFilter = 1

仅打印 'ReadmittedFilter'

中有 1 个的患者

但是，一旦我添加了日期范围（或任何其他参数），在许多情况下，它们会从打印输出中删除之前的访问。我想要实现的是强制打印患者之前的访问，即使它不适合输入的参数，并且参数仅适用于当前访问。

我将查询保存到存储过程中，并在 SSRS 2014 端生成具有不同参数的报告。

例如

目前没有参数：

Patient    VisitID  AdmitDate  DischargeDate PrevDisDate DaysBtwnVisits
John Doe   10001    10/1/13    10/5/13       NULL        NULL 
John Doe   10014    10/7/13    10/10/13      10/5/13     2
Jean All   10003    10/2/13    10/6/13       NULL        NULL
Jean All   10018    10/11/13   10/17/13      10/6/13     5
Jane Smith 10035    11/1/13    11/4/13       NULL        NULL
Jane Smith 10042    11/22/13   11/25/13      11/4/13     18

当前使用的参数：

@FromDischargeDate = '10/10/13'
@ThroughDischargeDate = '10/30/13'

输出：

Patient   VisitID  AdmitDate  DischargeDate PrevDisDate DaysBtwnVisits
John Doe  10004    10/7/13    10/10/13      10/5/13     2
Jean All  10018    10/11/13   10/17/13      10/6/13     5

我如何需要它使用参数：

@FromDischargeDate = '10/10/13'
@ThroughDischargeDate = '10/30/13'

输出：

Patient   VisitID  AdmitDate  DischargeDate PrevDisDate DaysBtwnVisits
John Doe  10001    10/1/13    10/5/13       NULL        NULL 
John Doe  10004    10/7/13    10/10/13      10/5/13     2
Jean All  10003    10/2/13    10/6/13       NULL        NULL
Jean All  10018    10/11/13   10/17/13      10/6/13     5

如果需要更多信息来对此进行调查，请告诉我。

谢谢。

Answer 1

试试这个：

SELECT TOP 2 UnitNumber,
       Patient,   
       VisitID,  
       AdmitDate,  
       DischargeDate, 
       PrevDisDate, 
       DaysBtwnVisits  
FROM #tblTempCalculations AS T1
WHERE T1.ReadmittedFilter = 1 AND
      T1.UnitNumber IN
      (SELECT UnitNumber
       FROM #tblTempCalculations AS T2
       WHERE DischargeDate BETWEEN @FromDischargeDate AND @ThroughDischargeDate)
ORDER BY DischargeDate DESC
