Answer 1

本周：

SELECT * 
FROM  your_table 
WHERE YEARWEEK(`your_date`) = YEARWEEK(CURDATE())

当月

SELECT * 
FROM  your_table 
WHERE YEAR(`your_date`) = YEAR(CURDATE())
  AND MONTH(`your_date`) = MONTH(CURDATE())

今年

SELECT * 
FROM  your_table 
WHERE YEAR(`your_date`) = YEAR(CURDATE())

Answer 2

选择当年的所有记录

Select *
FROM `table_name`
WHERE YEAR('hit_date') = YEAR(CURDATE());

选择当月的所有记录

Select *
FROM `table_name`
WHERE MONTH('hit_date') = MONTH(CURDATE())
AND YEAR('hit_date') = YEAR(CURDATE());

选择当前周的所有记录

Select *
FROM `table_name`
WHERE YEARWEEK('hit_date') = YEARWEEK(CURDATE());

请注意关于YEARWEEK，您可以指定您的周开始日取决于模式（第二个参数），请查看MySQL YEARWEEK() Function
