1、首先要构建一个时间维度表,下面给出通用的构建时间维度的存储过程:
USE [BI_DW]
GO
/****** Object: StoredProcedure [dbo].[proc_Dim_date] Script Date: 05/20/2016 11:35:58 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER proc [dbo].[proc_Dim_date]
as
begin
IF OBJECT_ID(\'dbo.Dim_Date\') IS NOT NULL
DROP TABLE dbo.[Dim_Date]
CREATE TABLE [dbo].[Dim_Date](
[DateKey] [int] NULL,
[Date] [datetime] NULL,
[Year] [float] NULL,
[Month] [float] NULL,
[Month EN] [nvarchar](50) NULL,
[Month Short EN] [nvarchar](50) NULL,
[Month CN] [nvarchar](50) NULL,
[Day] [float] NULL,
[Quarter] [float] NULL,
[Quarter EN] [nvarchar](50) NULL,
[Quarter CN] [nvarchar](50) NULL,
[Weekday] [float] NULL,
[Weekday CN] [nvarchar](50) NULL,
[Weekday Short EN] [nvarchar](50) NULL,
[Week of Year] [float] NULL,
[Day of Year] [float] NULL,
[SemiYearly] [nvarchar](50) NULL,
[Period of Ten Days] [nvarchar](10) NULL,
[Period of Index] [nvarchar](2) NULL,
[Weekend] [nvarchar](5) NULL
) ON [PRIMARY]
SET DATEFIRST 7 --设周日为每周的第一天
--向日期表插入数据
DECLARE @b1 DATETIME
set @b1=\'2010-01-01\' --设置起始日期
WHILE @b1<dateadd(day,2,GETDATE()) --设置截止日期
BEGIN

2、在数据库中构建这样的维度表之后,在SSAS出新建维度,这里就不再多说了。
重点介绍如何构建一个标准的时间维度,首先,打开维度设计选项卡,添加下面两套成员用来构建标准时间维度,按照图中的样子:
3、设置属性:
3.1 将Dim Date的属性“TYPE”设置为:Time
3.2 将带有“层级”的成员属性设置为:以“Day-层级”为例:Type =Days; KeyColumms =\'内容见“键列”图\',这里选择了组合键(确保在层级中“Day”是唯一的);所以需要设置NameColumns,将NameColumns=\'Day\'用来显示成员而已。
3.3 带有层级的其他成员都按照3.2的设置,具体有不同:Year-层级的Type=\'Years\' ,Month-层级的Type=\'Months\' ,Quater-层级的Type=\'Quaters\';当然还要选择NameColumn的相应字段用来显示。KeyColumns的组合字段的选择,只要符合保证唯一即可,例如Month的KeyColumns:
3.4 按照以上步骤,设置好之后,还是不行的,还需要将属性关系设置合理才行,按照下图的属性关系设置即可;设置成员的属性的时候,最好将成员的order by属性设置为“Key”,这样浏览的数据就会按照key排序了;除了带有层级的成员属性外,其他属性可以不需要额外设置即可;
3.5 这样处理维度,浏览查看效果:
