推荐答案
您可能想尝试一下:
-
这使您在2012年拥有261个工作日.
This gives you 261 working days for 2012.
现在,您需要了解周末以外的假期
Now you need to know your holidays that are not on a weekend
SELECT COUNT(*) FROM holidays WHERE DAYOFWEEK(holiday) < 6
其结果取决于您的假期表.
The result of this depends on your holiday table.
我们需要在一个查询中得到它:
We need to get that in one query:
SELECT 5 * (DATEDIFF('2012-12-31', '2012-01-01') DIV 7) + MID('0123444401233334012222340111123400012345001234550', 7 * WEEKDAY('2012-01-01') + WEEKDAY('2012-12-31') + 1, 1) - (SELECT COUNT(*) FROM holidays WHERE DAYOFWEEK(holiday) < 6)
应该是这样.
请注意,只有当结束日期高于开始日期时,此选项才能正常工作.
