SSRS 2012 - 针对 OLAP 评估多个参数

Question

我对 MDX 很陌生。我有一个名为 @MeasureType 的多选参数，它有 3 个可能的标签（我知道这个名字很混乱，但“Measure”在这里是一个行业术语）：

• 内容管理系统
• 赫迪斯
• CMS/HEDIS

@MeasureType 需要限制两列的结果：MeasureType 和 ContractType。

参数值逐字映射到 MeasureType。为了将它们映射到 ContractType，我们需要应用一些逻辑。逻辑如下：

• 如果@MeasureType = “CMS”，那么 Column2 应该是“CMS”
• 如果@MeasureType = “HEDIS”，那么 Column2 应该是“HEDIS”
• 如果 @MeasureType = “CMS/HEDIS”，则 Column2 应为“CMS”或“HEDIS”
• 如果@MeasureType 为全选，则 Column2 应为“CMS”或“HEDIS”或“其他”

为了让逻辑更清楚，这里是你可以用 SQL 编写它的方法（有更好的编写方法，但它明白了重点）：

-- Mimic multi-value parameter as if the user chose SELECT ALL
DECLARE @MeasureType TABLE (ParmValue varchar(20))

    INSERT @MeasureType VALUES ('CMS')
    INSERT @MeasureType VALUES ('HEDIS')
    INSERT @MeasureType VALUES ('CMS/HEDIS')

-- Mimic the logic to assign value(s) @ContractType based on user's selection of @MeasureType
DECLARE @ContractType TABLE (ParmValue varchar(20))

    IF (SELECT 1 FROM @MeasureType WHERE ParmValue = 'CMS') = 1 
        INSERT @ContractType VALUES ('CMS')

    IF (SELECT 1 FROM @MeasureType WHERE ParmValue = 'HEDIS') = 1
        INSERT @ContractType VALUES ('HEDIS')

    IF (SELECT 1 FROM @MeasureType WHERE ParmValue = 'CMS/HEDIS') = 1
        BEGIN
            INSERT @ContractType VALUES ('CMS')
            INSERT @ContractType VALUES ('HEDIS')
        END

    IF (SELECT 1 FROM @MeasureType WHERE ParmValue = 'CMS') = 1
    AND (SELECT 1 FROM @MeasureType WHERE ParmValue = 'HEDIS') = 1
    AND (SELECT 1 FROM @MeasureType WHERE ParmValue = 'CMS/HEDIS') = 1
        BEGIN
            INSERT @ContractType VALUES ('CMS')
            INSERT @ContractType VALUES ('HEDIS')
            INSERT @ContractType VALUES ('Other')
        END

-- Get the results
SELECT MeasureType,
       Measure1,
       Measure2
FROM   Table1
WHERE  MeasureType IN (SELECT ParmValue from @MeasureType)
AND    ContractType IN (SELECT ParmVaque from @ContractType)

我尝试了几种方法。

第一个是为@ContractType 创建第二个（隐藏）参数，我使用一系列评估Parameters!MeasureType.Label 的IIF 设置它。表达式是这样的：

=IIF(
JOIN(Parameters!MeasureType.Label) = "CMS CMS/HEDIS HEDIS", 
"[HealthPlan].[ContractType].&[CMS] [HealthPlan].[ContractType].&[HEDIS] [HealthPlan].[ContractType].&[Other]",
IIF( INSTR( JOIN(Parameters!MeasureType.Label), "CMS/HEDIS" ), 
    "[HealthPlan].[ContractType].&[CMS] [HealthPlan].[ContractType].&[HEDIS]",
     IIF( INSTR( JOIN(Parameters!MeasureType.Label), "CMS" ), 
     "[HealthPlan].[ContractType].&[CMS]",
     "[HealthPlan].[ContractType].&[HEDIS]" )
) )

然后我在数据集的“参数”选项卡中声明了这两个参数。我可以在查询设计器中运行 MDX，但是当我尝试预览报告时，我收到了这个错误……“‘[HealthPlan]’的语法不正确。”所以我认为参数构造一定有问题。我创建了几个文本框来查看参数的内容。选择所有选项时，请加入（参数！MeasureType.Value）如下所示：

• [Measure].[MeasureType].&[CMS] [Measure].[MeasureType].&[HEDIS] [Measure].[MeasureType].&[CMS/HEDIS]"

和参数！ContractType.Value 看起来像这样：

• [Measure].[MeasureType].&[CMS] [Measure].[MeasureType].&[HEDIS] [Measure].[MeasureType].&[Other]"

这似乎是正确的。这是我用于这种方法的 MDX...

SELECT NON EMPTY { [Measures].[Physician Count], 
                   [Measures].[Population], 
                   [Measures].[Unmet],[Measures].[Met] } ON COLUMNS,
 NON EMPTY { (NONEMPTY([Affiliation].[Affiliation1].[Affiliation1].Members, 
                       [Measures].[Population]) *

                       [Measures].[Population]) *
              NONEMPTY([Affiliation].[Affiliation3].[Affiliation3].Members, 
                       [Measures].[Population]) *
              NONEMPTY([Measure].[Registry].[Registry].Members, 
                       [Measures].[Population]) * 
              NONEMPTY(([Measure].[Measure].[Measure].Members,
                        [Measure].[MeasureKey].[MeasureKey].Members,
                        IIf (
                          StrToSet ( @MeasureType, CONSTRAINED ) .Count = 1,
                          StrToSet ( @MeasureType, CONSTRAINED ),
                          [Measure].[MeasureType].Members
                             )

                        ), [Measures].[Population]) *
              NONEMPTY(([Physician].[PCPNameCode].[PCPNameCode].Members, 
                        [Physician].[PCPID].[PCPID].Members, 
                        [Specialty].[Specialty].[Specialty].Members
                        ), [Measures].[Population]) ) 
            } 
              DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS 
FROM (
  SELECT ( StrToSet ( @MeasureType, CONSTRAINED ) ) ON COLUMNS
  FROM (
        SELECT ( StrToSet ( @ContractType, CONSTRAINED ) ) ON COLUMNS
        FROM [Model]
        )
      )
WHERE ( 
    IIf (
      StrToSet ( @ContractType, CONSTRAINED ) .Count = 1,
      StrToSet ( @ContractType, CONSTRAINED ),
      [HealthPlan].[ContractType].CurrentMember
    ) )
CELL Properties Value,BACK_COLOR,FORE_COLOR,FORMATTED_VALUE,FORMAT_STRING,FONT_NAME,FONT_SIZE,FONT_FLAGS

我尝试的另一种方法是通过使用 case 语句创建计算成员来评估 MDX 中的 @MeasureType。 MDX 如下。当我运行它时，我根本没有得到任何结果。

WITH MEMBER [HealthPlan].[ContractType].[ContractType2] 
AS
                CASE @MeasureType
                        WHEN "CMS" THEN "[HealthPlan].[ContractType].&[CMS]"
                        WHEN "CMS/HEDIS" THEN "[HealthPlan].[ContractType].&[CMS] [HealthPlan].[ContractType].&[HEDIS]"
                        WHEN "HEDIS" THEN "[HealthPlan].[ContractType].&[HEDIS]"
                        WHEN "CMS CMS/HEDIS HEDIS" THEN "[HealthPlan].[ContractType].&[CMS] [HealthPlan].[ContractType].&[HEDIS] [HealthPlan].[ContractType].&[Other]"
                END

SELECT NON EMPTY { [Measures].[Physician Count], [Measures].[Population], [Measures].[Unmet],[Measures].[Met] } ON COLUMNS,
 NON EMPTY { (NONEMPTY([Affiliation].[Affiliation1].[Affiliation1].Members, [Measures].[Population]) *
                          NONEMPTY([Affiliation].[Affiliation2].[Affiliation2].Members, [Measures].[Population]) *

                                                [Measure].[MeasureKey].[MeasureKey].Members,
                                                IIf (
                                                  StrToSet ( @MeasureType, CONSTRAINED ) .Count = 1,

FROM [Model]
WHERE [HealthPlan].[ContractType].[ContractType2] 
CELL Properties Value,BACK_COLOR,FORE_COLOR,FORMATTED_VALUE,FORMAT_STRING,FONT_NAME,FONT_SIZE,FONT_FLAGS

我现在迷路了。任何帮助都将不胜感激！

Answer 1

隐藏参数方法应该可以工作。创建 MDX 集的正确语法是：

{[HealthPlan].[ContractType].&[CMS], [HealthPlan].[ContractType].&[HEDIS]}

要仅测试参数，请使用尽可能短的查询，可能类似于以下内容

SELECT  { 
     [Measures].[Population] 
 } ON COLUMNS,
StrToSet ( @MeasureType, CONSTRAINED ) 
  ON ROWS
FROM [Model]

如果您遇到问题，请尝试在 SSMS 中构建 MDX 查询。使用 SSMS，您可以快速检查上述集合的语法是否正确（可能不正确，因为我没有多维数据集来测试它！）：

  SELECT  { 
    [Measures].[Population] 
   } ON COLUMNS,
   StrToSet ( '{[HealthPlan].[ContractType].&[CMS], [HealthPlan].[ContractType].&[HEDIS]}', 
  CONSTRAINED ) 
  ON ROWS
  FROM [Model]

一旦您知道构建集合需要哪些文本，您就可以设置报告服务表达式来构建文本。

Answer 2

这是对我有用的解决方案。使用正确的语法设置 @ContractType 是关键。感谢圆角！

@ContractType 设置为...

=IIF(
JOIN(Parameters!MeasureType.Label) = "CMS CMS/HEDIS HEDIS", 
"{[Member].[ContractType].&[CMS], [Member].[ContractType].&[HEDIS], [Member].[ContractType].&[Other]}",
IIF( INSTR( JOIN(Parameters!MeasureType.Label), "CMS/HEDIS" ), 
    "{[Member].[ContractType].&[CMS], [Member].[ContractType].&[HEDIS]}",
     IIF( INSTR( JOIN(Parameters!MeasureType.Label), "CMS" ), 
     "{[Member].[ContractType].&[CMS]}",
     "{[Member].[ContractType].&[HEDIS]}" )
) )

我正在使用的 MDX 是...

SELECT NON EMPTY { [Measures].[Physician Count], [Measures].[Population], [Measures].[Unmet],[Measures].[Met] } ON COLUMNS,
 NON EMPTY { (NONEMPTY([Affiliation].[Affiliation1].[Affiliation1].Members, [Measures].[Population]) *
              NONEMPTY([Affiliation].[Affiliation2].[Affiliation2].Members, [Measures].[Population]) *
              NONEMPTY([Affiliation].[Affiliation3].[Affiliation3].Members, [Measures].[Population]) *
              NONEMPTY(
                        (
                            [Measure].[Registry].[Registry].Members, 
                            [Measure].[Measure].[Measure].Members,
                            [Measure].[MeasureKey].[MeasureKey].Members,
                            StrToSet ( @MeasureType )
                          ), [Measures].[Population] 
                       ) *
              NONEMPTY(
                        (
                            StrToSet ( @ContractType )
                          ), [Measures].[Population] 
                       ) *
              NONEMPTY(
                        ([Physician].[PCPNameCode].[PCPNameCode].Members, 
                        [Physician].[PCPID].[PCPID].Members, 
                        [Physician].[Specialty].[Specialty].Members
                         ), [Measures].[Population]
                       ) 
             )
            } 
              DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS 
FROM [Model]
