让数据库产生一张详细的日历表

　　也许有了这张表，你的工作会轻松很多！ 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 < ’12/31/2004’ --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 GO select * from time_dimension
