代码如下: if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[f_getdate]') and xtype in (N'FN', N'IF', N'TF')) drop function [dbo].[f_getdate] GO create function [dbo].[f_getdate] ( @year int, --要查询的年份 @bz bit --@bz=0 查询工作日,@bz=1 查询休息日,@bz IS NULL 查询全部日期 ) RETURNS @re TABLE(Date datetime,Weekday nvarchar(3)) as begin DECLARE @tb TABLE(ID int ,Date datetime) insert @tb select number, dateadd(day,number,DATEADD(Year,@YEAR-1900,'1900-1-1')) from master..spt_values where type='P' and number between 0 and 366 DELETE FROM @tb WHERE Date>DATEADD(Year,@YEAR-1900,'1900-12-31') IF @bz=0 INSERT INTO @re(Date,Weekday) SELECT Date,DATENAME(Weekday,Date) FROM @tb WHERE (DATEPART(Weekday,Date)+@@DATEFIRST-1)%7 BETWEEN 1 AND 5 ELSE IF @bz=1 INSERT INTO @re(Date,Weekday) SELECT Date,DATENAME(Weekday,Date) FROM @tb WHERE (DATEPART(Weekday,Date)+@@DATEFIRST-1)%7 IN (0,6) ELSE INSERT INTO @re(Date,Weekday) SELECT Date,DATENAME(Weekday,Date) FROM @tb RETURN end go select * from dbo.[f_getdate]('2009',0)
