sql 获取本周周一和周日

存在问题,获取周日的时候,当当前时间正好是周日,会获取下一周的周日,而非本周周日.

select dateadd(week, datediff(week,0,CONVERT(DATETIME,GETDATE(),120)-1),0)

SELECT CONVERT(Varchar(100),DATEADD(DAY, 6, DATEADD(wk,  DATEDIFF(wk,0,getdate()),0)),120)

 版本2.0

看到版本1.0的代码,真的是有点随意,大写的小写的...

--周一
SELECT DATEADD(WEEK, DATEDIFF(WEEK, 0, CONVERT(DATETIME, GETDATE(), 120) - 1), 0);
--周日(最懒得办法,将获取的周一的数据,+6)
SELECT DATEADD(DAY, 6, DATEADD(WEEK, DATEDIFF(WEEK, 0, CONVERT(DATETIME, GETDATE(), 120) - 1), 0));
SELECT DATEADD(DAY, 6, DATEADD(WEEK, DATEDIFF(WEEK, 0, CONVERT(DATETIME, '2019-04-07 00:00:00.000', 120) - 1), 0));
