Question

我正在尝试获得在上午8点到下午4点之间批准的订单

SELECT 
    * 
FROM 
    orders 
WHERE 
    approved_date BETWEEN 'CURDATE() 8:00:00' AND 'CURDATE() 16:00:00'

在这里，我试图获得在下午4点之后（直到下午8点工作日）批准的订单

SELECT 
    * 
FROM 
    orders 
WHERE 
    approved_date BETWEEN 'CURDATE() 16:00:00' AND 'NEXT_WORKING_DAY 8:00:00'

如何正确编写这些查询？

approved_date 是 DATETIME 格式（0000-00-00 00:00:00）使用MySQL

编辑：工作日=星期一星期二星期四星期四星期四

Answer 1

使用timestampadd

timestampadd(HOUR, 16, CURDATE()) # 4 pm
timestampadd(HOUR, 32, CURDATE()) # 8 am the next day

Answer 2

将其用作：

timestampadd(HOUR, 16, CURDATE()) # same day 16:00

timestampadd(HOUR, 32, CURDATE()) # next day 8:00

Answer 3

这个怎么样？

 WHERE date(approved_date) = CURDATE() AND
       time(approved_date) BETWEEN '8:00:00' AND '16:00:00'

我不明白＆＃34; NEXT_WORKING_DAY＆＃34;＆＃34; NEXT_WORKING_DAY＆＃34;应该是的意思。也许就是这样：

WHERE date(approved_date) = CURDATE() AND time(approved_date) >= '8:00:00' OR
      date(approved_date = CURDATE() + 1 AND time(approved_date) <= '16:00:00'

SQL获取特定时间的当前日期
