How to calculate weekends of time range using MySQL
我需要使用 MySQL.
计算时间范围的周末
这是我目前的情况(关于计算工作日,但我想计算周末):
select
(floor(days / 7)* 5
+ days%7
- case
when 6 between wd and wd + days%7 - 1 then 1
else 0
end
- case
when 7 between wd and wd + days%7 - 1 then 1
else 0
end) as result
from
(
select
abs(datediff('2022-05-15', '2022-05-13')) + 1 as days,
weekday('2022-05-13') + 1 as wd ) as a;
希望我解释的好...
谢谢。
select
(floor(days / 7)* 2
+ case
when 6 between wd and wd + days%7 - 1 then 1
else 0
end
+ case
when 7 between wd and wd + days%7 - 1 then 1
else 0
end) as result
来自 ( select
abs(datediff('2022-05-15', '2022-05-13')) + 1 作为天数,
工作日('2022-05-13') + 1 作为 wd ) 作为 a;
也许这会奏效。试一试。
