SQLserver 向表中添加工作日，不排除节假日，只排出星期六星期日

--创建表 
create table WeekDays(
 id int primary key identity(1,1),
 WeekDay nvarchar(20),
 Status int --判断是否启用
 )

----添加一年的工作日
DECLARE @num int 
DECLARE @count int 
set @num = 1
set @count = 1 
WHILE @num <=365  --时间跨度有闰年的就是366天
begin 
INSERT into WeekDays VALUES (   convert(nvarchar(10),dateadd(dd,@num, ‘2017-07-05‘),23),1)--  2017-07-05 星期三
if @count=2
begin 
set @num = @num+3
set @count = @count+3
end 
else 
begin 
set @num = @num+1
set @count = @count+1 
end
IF @count = 8
set @count = 1
end
