时间维度表的建立

时间维度表，不管是在建立数据方还是在其他方面都有很多的用途,可以自己生成一张时间维表。我的同事老J做了一段存储过程可以实现时间维表的建立，该方法简便灵活，可以直接使用。

SET ANSI_NULLS ON

GO

SET QUOTED_IDENTIFIER ON

ALTER PROCEDURE [dbo].[Create_time_dimension]

    -- Add the parameters for the stored procedure here

AS

BEGIN

    -- SET NOCOUNT ON added to prevent extra result sets from

    -- interfering with SELECT statements.

SET NOCOUNT ON;

begin try

drop table [time_dimension]

end try

begin catch

end catch

CREATE TABLE [dbo].[time_dimension] (

   [time_id] [int] IDENTITY (1, 1) NOT NULL ,

   [the_date] [datetime] NULL ,

   [the_day] [nvarchar] (15) NULL ,

   [the_month] [nvarchar] (15) NULL ,

   [the_year] [smallint] NULL ,

   [day_of_month] [smallint] NULL ,

   [week_of_year] [smallint] NULL ,

   [month_of_year] [smallint] NULL ,

   [quarter] [nvarchar] (2) NULL ,

   [fiscal_period] [nvarchar] (20) NULL

) ON [PRIMARY]

DECLARE @WeekString varchar(12),

@dDate SMALLDATETIME,

@sMonth varchar(20),

@iYear smallint,

@iDayOfMonth smallint,

@iWeekOfYear smallint,

@iMonthOfYear smallint,

@sQuarter varchar(2),

@sSQL varchar(100),

@adddays int

  

SELECT @adddays = 1 --日期增量（可以自由设定）

SELECT @dDate = '01/01/2002' --开始日期

  

WHILE @dDate < '12/31/2010' --结束日期

BEGIN

  

   SELECT @WeekString = DATENAME (dw, @dDate)

   SELECT @sMonth=DATENAME(mm,@dDate)

   SELECT @iYear= DATENAME (yy, @dDate)

   SELECT @iDayOfMonth=DATENAME (dd, @dDate)

   SELECT @iWeekOfYear= DATENAME (week, @dDate)

   SELECT @iMonthOfYear=DATEPART(month, @dDate)

   SELECT @sQuarter = 'Q' + CAST(DATENAME (quarter, @dDate)as varchar(1))

   INSERT INTO time_dimension(the_date, the_day, the_month, the_year,

   day_of_month,

   week_of_year, month_of_year, quarter) VALUES

   (@dDate, @WeekString, @sMonth, @iYear, @iDayOfMonth, @iWeekOfYear,

   @iMonthOfYear, @sQuarter)

   SELECT @dDate = @dDate + @adddays

END

END

GO

SET ANSI_NULLS OFF

GO

SET QUOTED_IDENTIFIER OFF

GO

建立后的时间维度表如下所示。
