我想找出当前日期-30天之间的所有记录。但是无法为此编写MDX过滤器。我目前的疑问是:
WITH
SET [~FILTER] AS
{[Created_Date.Created_Hir].[Created_On].Members}
SET [~ROWS] AS
{[Sales Order Attributes SO.Sales_order].[Sales Order ID].Members}
SELECT
NON EMPTY {[Measures].[CONT_AMT_GROSS]} ON COLUMNS,
NON EMPTY [~ROWS] ON ROWS
FROM [SALES_ORDER]
WHERE [~FILTER]
获取所有记录。
答案 0 :(得分:1)
以下内容应作为您的日期"过滤"
Filter
(
[Created_Date].[Created_Hir].[Created_On].Members,
DateDiff
(
"d",
CDate([Created_Date].[Created_Hir].MEMBER_VALUE),
Now()
) <=30
)
如果您不想遇到性能问题,不要使用您在示例中使用的命名集。
如果表现不够好,请告诉我。

以下是今天在AdvWrks多维数据集中查找以及之前30天的示例:
WITH
MEMBER [Measures].[Key for Today] AS
Format
(
Now()
,'yyyyMMdd'
)
MEMBER [Measures].[Key for Today (AW)] AS
'2007' + Right([Measures].[Key for Today],4)
MEMBER [Measures].[Today string] AS
'[Date].[Calendar].[Date].&[' + [Measures].[Key for Today (AW)] + ']'
SET [Today] AS
StrToMember
(
[Measures].[Today string]
,constrained
)
SET [Last30Days] AS
[Today].Item(0).Item(0).Lag(30) : [Today].Item(0).Item(0)
SELECT
{} ON 0
,[Last30Days] ON 1
FROM [Adventure Works];
结果如下:
因此,如果我们想修改上述内容,以便我们只获得过去30天的互联网销售额:
WITH
MEMBER [Measures].[Key for Today] AS
Format
(
Now()
,'yyyyMMdd'
)
MEMBER [Measures].[Key for Today (AW)] AS
'2007' + Right([Measures].[Key for Today],4)
MEMBER [Measures].[Today string] AS
'[Date].[Calendar].[Date].&[' + [Measures].[Key for Today (AW)] + ']'
SET [Today] AS
StrToMember
(
[Measures].[Today string]
,constrained
)
SET [Last30Days] AS
[Today].Item(0).Item(0).Lag(30) : [Today].Item(0).Item(0)
MEMBER [Date].[Calendar].[All].[Last30Days] AS
Aggregate([Last30Days])
SELECT
{[Measures].[Internet Sales Amount]} ON 0
FROM [Adventure Works]
WHERE [Date].[Calendar].[All].[Last30Days];
应用于您的场景,上面的内容将如下所示:
WITH
MEMBER [Measures].[Key for Today] AS
Format
(
Now()
,'yyyyMMdd'
)
MEMBER [Measures].[Today string] AS
'[Created_Date.Created_Hir].[Created_On].&[' + [Measures].[Key for Today] + ']'
SET [Today] AS
StrToMember
(
[Measures].[Today string]
,constrained
)
SET [~FILTER] AS
[Today].Item(0).Item(0).Lag(30) : [Today].Item(0).Item(0)
MEMBER [Created_Date.Created_Hir].[All].[~FILTERaggregated] AS
//MEMBER [Created_Date.Created_Hir].[Created_On].[All].[~FILTERaggregated] AS //<<if above is throwing an exception then try this instead
Aggregate([~FILTER])
SET [~ROWS] AS
{
[Sales Order Attributes SO.Sales_order].[Sales Order ID].MEMBERS
}
SELECT
NON EMPTY
{[Measures].[CONT_AMT_GROSS]} ON COLUMNS
,NON EMPTY
[~ROWS] ON ROWS
FROM [SALES_ORDER]
WHERE
[Created_Date.Created_Hir].[All].[~FILTERaggregated];
