MySQL 的 YEARWEEK 是获取年份和周数的一个函数,函数形式为 YEARWEEK(date[,mode])

例如 2010-3-14 ,礼拜天

SELECT YEARWEEK('2010-3-14') 返回 11
SELECT YEARWEEK('2010-3-14',1) 返回 10

其中第二个参数是 mode ,具体指的意思如下:

Mode First day of week Range Week 1 is the first week …
0 Sunday 0-53 with a Sunday in this year
1 Monday 0-53 with more than 3 days this year
2 Sunday 1-53 with a Sunday in this year
3 Monday 1-53 with more than 3 days this year
4 Sunday 0-53 with more than 3 days this year
5 Monday 0-53 with a Monday in this year
6 Sunday 1-53 with more than 3 days this year
