使用CDate和DateDiff的Mondrian MDX错误

Question

下面怎么解决问题？

错误：mondrian.olap.fun.MondrianEvaluationException：mondrian.olap.InvalidArgumentException：Mondrian错误：参数无效。必须正确格式化CDate函数的表达式参数

我的MDX请求：

WITH
MEMBER 
    [Measures].[diff] as 'datediff("d",CDate([TimeDim.TimeHir].CurrentMember.Name),now())'
....

Answer 1

您是否尝试过其他会员资产：

WITH
MEMBER [Measures].[diff] as 
'datediff("d",CDate([TimeDim.TimeHir].CurrentMember.MEMBER_VALUE),now())'

或

WITH
MEMBER [Measures].[diff] as
 'datediff("d",CDate([TimeDim.TimeHir].CurrentMember.MEMBER_key),now())'

或

WITH
MEMBER [Measures].[diff] as 
 'datediff("d",CDate([TimeDim.TimeHir].CURRENTMEMBER.Properties('Key0', Typed)),now())'

修改

这个对我有用AdvWks：

WITH

MEMBER [Measures].[Date_MEMBER_VALUE] as 
  [Date].[Calendar].CurrentMember.MEMBER_VALUE
MEMBER [Measures].[Diff_MEMBER_VALUE] as 
  datediff("D",CDate([Measures].[Date_MEMBER_VALUE]),now())

SELECT
{
[Measures].[Date_MEMBER_VALUE]
,[Measures].[Diff_MEMBER_VALUE]
} 
ON 0,
tail([Date].[Calendar].[Date],12) ON 1
FROM [Adventure Works];

编辑

从这里看起来似乎.MEMBER_VALUE在Mondrian中不存在，所以请尝试使用上面的代码而不只是.VALUE：http://mondrian.pentaho.com/documentation/mdx.php

您可以使用DateSerial函数将您的值转换为CDate

接受的日期时间格式
