SQL日历表数据的简单生成

为了公司考勤系统的需要
编写的几个简单存储过程(可以手动运行,也可以设置事务自动运行!感觉还行比较通用,写出来共享下)
Calendar表结构很简单,2个字段:
fdDate 日期
fdType 考勤类型(工作日N,周末W,节假日H[需要根据需要自己修改])
--判断一段时间范围内的工作日（N）和周末（W）
Create     PROCEDURE [dbo].[NewMonthWeekDay_Calendar]
@sdate smalldatetime,
@edate smalldatetime
AS
declare @fdDate smalldatetime
declare @WeekDay varchar(20)
declare cr0 cursor for
 select fdDate from calendar where fddate>=@sdate and fddate<=@edate
open cr0
fetch next from cr0 into @fdDate
 while @@fetch_status=0
 begin
  if (datename(weekday,@fdDate)='星期一')
   update calendar set fdType='N' where fdDate=@fdDate
  if (datename(weekday,@fdDate)='星期二')
   update calendar set fdType='N' where fdDate=@fdDate
  if (datename(weekday,@fdDate)='星期三')
   update calendar set fdType='N' where fdDate=@fdDate
  if (datename(weekday,@fdDate)='星期四')
   update calendar set fdType='N' where fdDate=@fdDate
  if (datename(weekday,@fdDate)='星期五')
   update calendar set fdType='N' where fdDate=@fdDate
  if (datename(weekday,@fdDate)='星期六')
   update calendar set fdType='W' where fdDate=@fdDate
  if (datename(weekday,@fdDate)='星期日')
   update calendar set fdType='W' where fdDate=@fdDate
  
  fetch next from cr0 into @fdDate
 end
close cr0
deallocate cr0 
--根据年和月自动插入Calendar表新日期数据
Create    PROCEDURE [dbo].[NewMonth_Calendar]
@Year int,
@Month int
AS
 Select TOP 50 ID = Identity(Int, 0, 1) Into #T from SysColumns
 insert into cas..calendar(fdDate)
 Select Convert(Varchar(10), DateAdd(dd, ID, Cast(Rtrim(@Year) + '-' + Rtrim(@Month) + '-' + '01' As DateTime)), 120) from #T
