Question

如何返回两个日期之间的天数减去该时段的周六和周日的数量？ mysql上的DATEDIFF函数为我提供了天数，但不排除周末。

例如，我有两列，并想添加第三列，这是两者之间的区别。

我将不胜感激。

Answer 1

尝试使用此

声明@ Date1日期时间，@ Date2日期时间；

选择@ Date1 ='8/1/2018'，@ Date2 ='8/7/2018'

选择Datediff（dd，@ Date1，@ Date2）-（Datediff（wk，@ Date1，@ Date2）* 2）- Datepart（dw，@ Date1）= 1然后1其他0 End +的情况 Datepart（dw，@ Date2）= 1然后1其他0结尾的情况
