Question

我对这整个MDX查询都很新。我有以下查询，我试图执行，但不断收到以下错误：

执行查询... Query（19,16）STRTOSET函数需要1参数的字符串或数字表达式。使用元组集表达式。执行完成

我的查询如下：

   SELECT 
NON EMPTY { [Measures].[Effective Duration] } ON COLUMNS, 
NON EMPTY { (
                [Dim Cause Code].[Cause].[Cause].ALLMEMBERS * 
                [Dim Classification].[Classification].[Classification].ALLMEMBERS * 
                [Dim Date 1].[Full Date Alternate Key].[Full Date Alternate Key].ALLMEMBERS * 
                [Dim Location 1].[Work Center Name].[Work Center Name].ALLMEMBERS * 
                [Fact Process Downtime].[Start Datetime].[Start Datetime].ALLMEMBERS * 
                [Fact Process Downtime].[End Datetime].[End Datetime].ALLMEMBERS * 
                [Fact Process Downtime].[Id].[Id].ALLMEMBERS ) 
            } DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS FROM ( 
    SELECT ( STRTOSET({[Fact Process Downtime].[Is Virtual].&[False]}, CONSTRAINED) ) ON COLUMNS 
    FROM ( 
            SELECT ( STRTOSET({[Dim Location 1].[Work Center].&[South32 Manganese.Mamatwan.DMS]}, CONSTRAINED) ) ON COLUMNS 
            FROM ( 
                    SELECT ( STRTOSET({[Dim Classification].[Classification].&[Scheduled Process]}, CONSTRAINED) ) ON COLUMNS 
                    FROM ( 
                            SELECT ( STRTOSET({[Dim Date 1].[Month Fiscal Year].&[Jul/17]}, CONSTRAINED) ) ON COLUMNS FROM [FactDownTime])))) WHERE ( 
    IIF( STRTOSET({[Dim Date 1].[Month Fiscal Year].&[Jul/17]}, CONSTRAINED).Count = 1, STRTOSET({[Dim Date 1].[Month Fiscal Year].&[Jul/17]}, CONSTRAINED), [Dim Date 1].[Month Fiscal Year].currentmember ), 
    IIF( STRTOSET(STRTOSET({[Dim Location 1].[Work Center].&[South32 Manganese.Mamatwan.DMS]}, CONSTRAINED).Count = 1, STRTOSET(STRTOSET({[Dim Location 1].[Work Center].&[South32 Manganese.Mamatwan.DMS]}, CONSTRAINED), [Dim Location 1].[Work Center].currentmember ), 
    IIF( STRTOSET({[Fact Process Downtime].[Is Virtual].&[False]}, CONSTRAINED).Count = 1, STRTOSET({[Fact Process Downtime].[Is Virtual].&[False]}, CONSTRAINED), [Fact Process Downtime].[Is Virtual].currentmember ) 
  )))

你需要为这个函数提供字符串strToSet是＆＃34; String to Set＆＃34;

的缩写

https://msdn.microsoft.com/en-us/library/ms144782.aspx

所以这是不正确的：

STRTOSET({[Fact Process Downtime].[Is Virtual].&[False]}, CONSTRAINED)

但这是正确的

STRTOSET('{[Fact Process Downtime].[Is Virtual].&[False]}', CONSTRAINED))

strToSet函数的主要用例是将参数传递到来自SSRS的mdx查询时，因此很少使用这样的语法：

STRTOSET('{[Fact Process Downtime].[Is Virtual].&[False]}', CONSTRAINED))

如果不涉及参数，那么只需摆脱STRTOSET：

{[Fact Process Downtime].[Is Virtual].&[False]}

如果您需要使用参数，请查看@ alejandrozuleta最近的优秀答案：

MDX SSRS Parameter category chooses all sub category

如果参数不重要，那么您的脚本可能会简化为以下内容：

SELECT 
NON EMPTY [Measures].[Effective Duration] ON 0, 
NON EMPTY 
    [Dim Cause Code].[Cause].[Cause].ALLMEMBERS * 
    [Dim Classification].[Classification].[Classification].ALLMEMBERS * 
    [Dim Date 1].[Full Date Alternate Key].[Full Date Alternate Key].ALLMEMBERS * 
    [Dim Location 1].[Work Center Name].[Work Center Name].ALLMEMBERS * 
    [Fact Process Downtime].[Start Datetime].[Start Datetime].ALLMEMBERS * 
    [Fact Process Downtime].[End Datetime].[End Datetime].ALLMEMBERS * 
    [Fact Process Downtime].[Id].[Id].ALLMEMBERS 
  ON 1 
FROM 
( 
    SELECT 
        [Fact Process Downtime].[Is Virtual].&[False] ON 0, 
        [Dim Location 1].[Work Center].&[South32 Manganese.Mamatwan.DMS] ON 1, 
        [Dim Classification].[Classification].&[Scheduled Process] ON 2, 
        [Dim Date 1].[Month Fiscal Year].&[Jul/17] ON 3 
    FROM [FactDownTime]
);

STRTOSET函数需要1参数的字符串或数字表达式。使用元组集表达式
