创建时间维度表的存储过程
在建立BI数据仓库时，时常需要用到时间维度，通过存储过程一次性批量生成，语句如下：
?
create PROCEDURE [dbo].[Create_time_by_day_dimension] -- Add the parameters for the stored procedure hereASBEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements.SET NOCOUNT ON;begin trydrop table [time_by_day_dimension]end trybegin catchend catchCREATE TABLE [dbo].[time_by_day_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 intSELECT @adddays = 1 --日期增量（可以自由设定）SELECT @dDate = '01/01/2008' --开始日期WHILE @dDate < '12/31/2011' --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_by_day_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 + @adddaysENDEND
