Sql 更改一周的开始日期黑斑羚

我试图改变一周的开始日期，但无法实现 现在是星期一到星期天，应该是星期天到星期六 我尝试在以下数据集

发票日期

和

发票周

 SELECT invoice_date,
        weekofyear(invoice_date) as invoice_week,
        datesub(invoice_date,1),
        weekofyear(datesub(invoice_date,1)) as invoice_week1 
   from table

---

我认为不应该用1减去日期，而应该用1加上日期：

select 
        invoice_date,
        weekofyear(invoice_date) as invoice_week,
        adddate(invoice_date,1),
        weekofyear(adddate(invoice_date,1)) as invoice_week1 
from(
        select cast('2018-01-07 16:00:00' as timestamp) invoice_date
)stg

找到了一个有效的解决方案。给定一个日期，如果您想要周日-周六周，而不是默认的周一-周日周，那么这里是一周开始和结束的日期

SET var:date=2019-01-06;
select  to_date(IF( dayofweek(cast('${var:date}' as timestamp)) = 1, cast('${var:date}' as timestamp), trunc(cast('${var:date}' as timestamp), 'd') - interval 1 day)) as startOfWeek, to_date(IF( dayofweek(cast('${var:date}' as timestamp)) = 1, (trunc(cast('${var:date}' as timestamp) + interval 1 day, 'd') + interval 5 day), (trunc(cast('${var:date}' as timestamp), 'd') + interval 5 day) )) as endOfWeek;
