创建日期时间维度数据

方式一、

1建表：

CREATE TABLE [dbo].[Dim_Date](
	[DateKey] [int] NULL,					--日期编号
	[Date] [datetime] NULL,					--日期
	[Year] [float] NULL,					--年
	[Month] [float] NULL,					--月
	[Month EN] [nvarchar](50) NULL,			--月【英文表示】
	[Month Short EN] [nvarchar](50) NULL,	--月【英文表示简称】
	[Month CN] [nvarchar](50) NULL,			--月【中文表示】
	[Day] [float] NULL,						--天
	[Quarter] [float] NULL,					--季度
	[Quarter EN] [nvarchar](50) NULL,		--季度【英文表示】	
	[Quarter CN] [nvarchar](50) NULL,		--季度【中文表示】
	[Weekday] [float] NULL,					--周
	[Weekday CN] [nvarchar](50) NULL,		--周【中文表示】
	[Weekday Short EN] [nvarchar](50) NULL,	--周【英文简称表示】
	[Week of Year] [float] NULL,			--一年中的第几周
	[Day of Year] [float] NULL,				--一年中的第几天
	[SemiYearly] [nvarchar](50) NULL,		--半年
	[Period of Ten Days] [nvarchar](10) NULL,--旬【中文表示】
	[Period of Index] [nvarchar](2) NULL,	--旬【英文表示】
	[Weekend] [nvarchar](5) NULL			--工作日
) ON [PRIMARY]

GO

 2.建存储过程

SET DATEFIRST 7 --设周日为每周的第一天
GO
--向日期表插入数据
DECLARE @b1 DATETIME
set @b1='2000-01-01'     --设置起始日期 
 
WHILE @b1<'2014-01-01'   --设置截止日期
BEGIN

  [Quarter CN],
  [Weekday],
  [Weekday CN],
  [Weekday Short EN],
  [Week of Year],
  [Day of Year],

  [Period of Index] ,
  [Weekend]

 方式二、

-- 上面生成日期，下边用视图生成 年、半年、季、月、日等
go
create table tbl_MetaData_Date
(
[Date] [datetime] NOT NULL,
[Ten_Days] [datetime] NULL,
[Half_Year] [datetime] NULL
) ON [PRIMARY]
go

 
create view v_metadata_date
as
select date, year(date) as year, month(date) as month, day(date) as day, case when datepart(weekday, date) = 1 then datediff(wk, convert(datetime,
dateadd(yy, datediff(yy, 0, date), 0)), date) when datepart(weekday, date) > 1 then datediff(wk, convert(datetime, dateadd(yy, datediff(yy, 0,
date), 0)), date) + 1 end as week, { fn quarter(date) } as quarter, ten_days, half_year, date as dayne
