Question

我有一个选择语句，根据存储过程中包含的“程序”，“观察”或“条件”进行过医生访问的患者数量得出计数。我使用'procedure'，'observation'和'condition'作为可选参数。 'procedure'，'condition'和'observation'都存储在不同的表中。目标是计算在一段时间内具有“程序”，“观察”或“条件”的患者数量的“分子”值。

看起来如果同一患者有多个'程序'，多个'观察'或多个'条件'，'计数'得出所有这些而不是用于输入存储的特定'分子'值。程序。

Parameter declarations: 
@CareSite VARCHAR(1000),       /* where visit occurs */
@AgeStart VARCHAR(10),         /* starting age patient's age falls in */
@AgeEnd VARCHAR(10),           /* ending age patient's age falls in */
@Gender VARCHAR(10),           /* 'men' or 'women'
@Procedure_Numerator VARCHAR(1000)=null,  /* procedure the visit is for */
@Condition_Numerator VARCHAR(1000)=null,  /* condition the visit is for */
@Observation_Numerator VARCHAR(1000)=null /* observation the visit is for */

SELECT statement: 

DECLARE @D1NumVal INT 
    SET @D1NumVal = (SELECT COUNT(*) AS Numerator  
                       FROM SAS2SQL_DenominatorPersonTest DPT
                       JOIN SAS2SQL_DenominatorProcedureTest DPRT
                         ON DPRT.PersonID = DPT.PersonID 
                       JOIN SAS2SQL_DenominatorConditionTest DCT
                         ON DCT.Person_ID = DPT.PersonID
                       JOIN SAS2SQL_DenominatorObservationsTest DOT
                         ON DOT.PersonID = DPT.PersonID
                      WHERE DPT.D1 = 1
                        AND DPT.Age >= @AgeStart AND DPT.Age <= @AgeEnd
                        AND (@Procedure_Numerator IS NOT NULL AND 
                             DPT.CareSiteName = @CareSite AND DPT.Wave = 
                             @Wave 
                             AND DPT.Gender = @Gender AND 
                             DPRT.ProcudureSourceValue = 
                             @Procedure_Numerator)
                         OR (@Condition_Numerator IS NOT NULL AND 
                             DPT.CareSiteName = @CareSite AND DPT.Wave =    
                             @Wave 
                         AND DPT.Gender = @Gender AND 
                             DCT.X_Condition_Source_Desc = 
                             @Condition_Numerator)
                          OR (@Observation_Numerator IS NOT NULL AND 
                             DPT.CareSiteName = @CareSite AND DPT.Wave = 
                             @Wave 
                             AND DPT.Gender = @Gender AND 
                             DOT.ObservationSourceValue = 
                             @Observation_Numerator))

我尝试使用'CASE WHEN'方法，但我上面的内容返回的结果更接近我想要生成的内容。

您可能需要添加括号，因为AND在OR之前，第二AND之后和最后一个之后进行评估。

这似乎符合您的描述：

DECLARE @D1NumVal INT 
    SET @D1NumVal = (SELECT COUNT(*) AS Numerator  
                       FROM SAS2SQL_DenominatorPersonTest DPT
                       JOIN SAS2SQL_DenominatorProcedureTest DPRT
                         ON DPRT.PersonID = DPT.PersonID 
                       JOIN SAS2SQL_DenominatorConditionTest DCT
                         ON DCT.Person_ID = DPT.PersonID
                       JOIN SAS2SQL_DenominatorObservationsTest DOT
                         ON DOT.PersonID = DPT.PersonID
                      WHERE DPT.D1 = 1
                        AND DPT.Age >= @AgeStart AND DPT.Age <= @AgeEnd
                        AND((@Procedure_Numerator IS NOT NULL AND 
                             DPT.CareSiteName = @CareSite AND DPT.Wave = 
                             @Wave 
                             AND DPT.Gender = @Gender AND 
                             DPRT.ProcudureSourceValue = 
                             @Procedure_Numerator)
                         OR (@Condition_Numerator IS NOT NULL AND 
                             DPT.CareSiteName = @CareSite AND DPT.Wave =    
                             @Wave 
                         AND DPT.Gender = @Gender AND 
                             DCT.X_Condition_Source_Desc = 
                             @Condition_Numerator)
                          OR (@Observation_Numerator IS NOT NULL AND 
                             DPT.CareSiteName = @CareSite AND DPT.Wave = 
                             @Wave 
                             AND DPT.Gender = @Gender AND 
                             DOT.ObservationSourceValue = 
                             @Observation_Numerator)))

Where子句返回Count（）的所有行而不是特定行
