MDX 查询 STRTOSET CONSTRAINED 标志

Question

我不熟悉 MDX 语言，我遇到了数据集 (DataBatchProcessData) 的问题，这是 MDX 查询：

SELECT 
  NON EMPTY 
    {
      [Measures].[Germ1 Delta Temp In Out Inf]
     ,[Measures].[Germ2 Delta Temp In Out Sup]
     ,[Measures].[Germ2 Delta Temp In Out Inf]
     ,[Measures].[Germ1 Delta Temp In Out Sup]
     ,[Measures].[Germ Nb Sprays]
    } ON COLUMNS
 ,NON EMPTY 
    {
        [65 Batch Process Data].[Batch Number].[Batch Number].ALLMEMBERS*
        [01 Plants].[Plant Name].[Plant Name].ALLMEMBERS*
        [04 Production Units].[Production Unit].[Production Unit].ALLMEMBERS*
        [65 Batch Process Data].[Steeping Start Date].[Steeping Start Date].ALLMEMBERS
    }
  DIMENSION PROPERTIES 
    MEMBER_CAPTION
   ,MEMBER_UNIQUE_NAME
   ON ROWS
FROM 
(
  SELECT 
    StrToSet
    ("{[65 Batch Process Data].[Batch Number].&[1320165073],[65 Batch Process Data].[Batch Number].&[1320165074],[65 Batch Process Data].[Batch Number].&[1320165075]}"
     ,CONSTRAINED
    ) ON COLUMNS
  FROM 
  (
    SELECT 
      StrToSet
      ("[04 Production Unit].[Production Unit].&[1]"
       ,CONSTRAINED
      ) ON COLUMNS
    FROM 
    (
      SELECT 
        StrToSet
        ("[01 Plants].[Plant Name].&[Rostock]"
         ,CONSTRAINED
        ) ON COLUMNS
      FROM [Supervision]
    )
  )
)
CELL PROPERTIES 
  VALUE
 ,BACK_COLOR
 ,FORE_COLOR
 ,FORMATTED_VALUE
 ,FORMAT_STRING
 ,FONT_NAME
 ,FONT_SIZE
 ,FONT_FLAGS;

此 MDX 查询由 SSRS 自动生成，但无法正常工作，我在运行生成报告时遇到此错误：

Query (8, 9) The restrictions imposed by the CONSTRAINED flag in the STRTOSET function were violated.

我得到了另一个与此数据集非常相似的数据集 (DataGermination)，它采用相同的参数（但不在同一维度）：

SELECT 
  NON EMPTY 
    {
      [Measures].[Air Temperature Out - Fact Germination Continue]
    } ON COLUMNS
 ,NON EMPTY 
    {
        [81 Germination Continue].[Batch Number].[Batch Number].ALLMEMBERS*
        [80 Germination General].[Plant Name].[Plant Name].ALLMEMBERS*
        [80 Germination General].[Production Unit].[Production Unit].ALLMEMBERS*
        [81 Germination Continue].[Characteristic Date].[Characteristic Date].ALLMEMBERS*
        [80 Germination General].[Start Date  Unloading].[Start Date  Unloading].ALLMEMBERS*
        [80 Germination General].[Start Date].[Start Date].ALLMEMBERS*
        [80 Germination General].[End Date].[End Date].ALLMEMBERS
    }
  DIMENSION PROPERTIES 
    MEMBER_CAPTION
   ,MEMBER_UNIQUE_NAME
   ON ROWS
FROM 
(
  SELECT 
    StrToSet
    ("[80 Germination General].[Production Unit].&[1]"
     ,CONSTRAINED
    ) ON COLUMNS
  FROM 
  (
    SELECT 
      StrToSet
      ("[80 Germination General].[Plant Name].&[Rostock]"
       ,CONSTRAINED
      ) ON COLUMNS
    FROM 
    (
      SELECT 
        StrToSet
        ("{[81 Germination Continue].[Batch Number].&[1320165073],[81 Germination Continue].[Batch Number].&[1320165074],[81 Germination Continue].[Batch Number].&[1320165075]}"
         ,CONSTRAINED
        ) ON COLUMNS
      FROM [Supervision]
    )
  )
)
CELL PROPERTIES 
  VALUE
 ,BACK_COLOR
 ,FORE_COLOR
 ,FORMATTED_VALUE
 ,FORMAT_STRING
 ,FONT_NAME
 ,FONT_SIZE
 ,FONT_FLAGS;

当我运行在 SSMS 中查询这些时，第二个正在工作（DataGermination），但我不知道为什么，数据集 DataBatchProcessData 没有。

Answer 1

我怀疑您指定的成员之一在多维数据集中不存在。

易于测试。

如果您将以下内容添加到一个非常非常简单的mdx 脚本中，是否可以运行?

{[65 Batch Process Data].[Batch Number].&[1320165073]
,[65 Batch Process Data].[Batch Number].&[1320165074]
,[65 Batch Process Data].[Batch Number].&[1320165075]}

仅以下内容可以说明它是否识别这些成员：

SELECT 
  {} ON ROWS
 ,{
    [81 Germination Continue].[Batch Number].&[1320165073]
   ,[81 Germination Continue].[Batch Number].&[1320165074]
   ,[81 Germination Continue].[Batch Number].&[1320165075]
  } ON COLUMNS
FROM [Supervision];

Answer 2

来自 BOL：

When the CONSTRAINED flag is used, the set specification must contain qualified or unqualified member names or a set of tuples containing qualified or unqualified member names enclosed by braces {}. This flag is used to reduce the risk of injection attacks via the specified string. If a string is provided that is not directly resolvable to qualified or unqualified member names, the following error appears: "The restrictions imposed by the CONSTRAINED flag in the STRTOSET function were violated.

您似乎没有为属性使用完全限定的成员名称。

需要

Dimension Name.Hierarchy Name.Level Name.Member Name

或

Dimension Name.Hierarchy Name.Level Name.&[Member Value]

Answer 3

你是对的 SouravA，我的问题是批号。

它期待 [65 Batch Process Data].[Batch Number].&[Batch Number]&[Plant Code]&[Production Unit]

我给他的时候[65 Batch Process Data].[Batch Number].&[Batch Number]

感谢您的帮助！
