Properties (MDX)

返回一个包含成员属性值的字符串，或返回一个强类型值。

语法

Member_Expression.Properties(Property_Name [, TYPED])

参数

  • Member_Expression
    返回成员的有效多维表达式 (MDX)。

  • Property_Name
    成员属性名称的有效字符串表达式。

注释

Properties 函数返回指定成员属性的指定成员值。成员属性可以是任何内部成员属性（如 NAME、ID、KEY、或 CAPTION），也可以是用户定义的成员属性。有关详细信息，请参阅内部成员属性 (MDX) 和用户定义的成员属性 (MDX)。

默认情况下，将该值强迫为一个字符串。如果指定了 TYPED，则返回值为强类型。

  • 如果属性是内部的，则函数返回成员的原始类型。

  • 如果属性是用户定义的，则返回值的类型与 MemberValue 函数的返回值类型相同。

注意注意

Properties ('Key') 返回与 Key0 相同的结果，但组合键除外。Properties ('Key') 将为组合键返回 null。将 Keyx 语法用于组合键，如示例中所示。Properties('Key0')、Properties('Key1')、Properties('Key2') 等共同构成了组合键。

示例

下例既返回内部属性也返回用户定义成员属性，并且利用 TYPED 参数返回“星期几”成员属性的强类型值。

WITH MEMBER Measures.MemberName AS 
   [Date].[Calendar].[July 1, 2003].Properties('Name')
MEMBER Measures.MemberVal AS 
   [Date].[Calendar].[July 1, 2003].Properties('Member_Value')
MEMBER Measures.MemberKey AS

MEMBER Measures.MemberID AS 
   [Date].[Calendar].[July 1, 2003].Properties('ID')
MEMBER Measures.MemberCaption AS 
   [Date].[Calendar].[July 1, 2003].Properties('Caption')

MEMBER Measures.DayofWeek AS 
   [Date].[Calendar].[July 1, 2003].Properties('Day of Week')
MEMBER Measures.DayofMonth AS 
   [Date].[Calendar].[July 1, 2003].Properties('Day of Month')
MEMBER Measures.DayofYear AS 
   [Date].[Calendar].[July 1, 2003].Properties('Day of Year')

以下示例说明了 KEYx 属性的用法。

WITH 
MEMBER Measures.MemberKey AS 
   [Customer].[Customer Geography].[State-Province].&[QLD]&[AU].Properties('Key')
MEMBER Measures.MemberKey0 AS 
   [Customer].[Customer Geography].[State-Province].&[QLD]&[AU].Properties('Key0')
MEMBER Measures.MemberKey1 AS 
   [Customer].[Customer Geography].[State-Province].&[QLD]&[AU].Properties('Key1')
 
SELECT {Measures.MemberKey
   , Measures.MemberKey0
   , Measures.MemberKey1   
   }  ON 0
