使用游标循环添加某一年日期（星期几）数据到数据表

直接上代码

DECLARE @BeginTime datetime
DECLARE My_Cursor CURSOR --定义游标
FOR (select dateadd(day,x,col) from 
(
select cast('2020-3-16 08:00:00' as datetime) as col --从2020年3月16日开始计算
)a cross join 
(
SELECT top 365 b8.i+b7.i + b6.i + b5.i + b4.i +b3.i +b2.i + b1.i + b0.i x
FROM(SELECT 0 i UNION ALL SELECT 1) b0
CROSS JOIN(SELECT 0 i UNION ALL SELECT 2) b1
CROSS JOIN(SELECT 0 i UNION ALL SELECT 4) b2
CROSS JOIN(SELECT 0 i UNION ALL SELECT 8) b3
CROSS JOIN(SELECT 0 i UNION ALL SELECT 16) b4
CROSS JOIN(SELECT 0 i UNION ALL SELECT 32) b5
CROSS JOIN(SELECT 0 i UNION ALL SELECT 64) b6
CROSS JOIN(SELECT 0 i UNION ALL SELECT 128) b7
CROSS JOIN(SELECT 0 i UNION ALL SELECT 256) b8
order by 1
)b
where datepart(dw,dateadd(day,x,col))=5 --5为星期四，2是星期一
