代碼如下:

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, --要查詢的年份 
@bz bit --@bz=0 查詢工作日,@bz=1 查詢休息日,@bz IS NULL 查詢全部日期 
) 
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)
