查询以查找给定时间范围内每天的记录计数

Question

我需要在给定日期范围内的每天上午9点至下午6点之间对表中的记录数进行计数。

样本输出应类似于：

Date          Count of users
01-11-2018    100
02-11-2018    88
03-11-2018    107
04-11-2018    113

Answer 1

SELECT DATE(date), count(*) 
FROM table 
WHERE TIME(date) BETWEEN TIME('9:00:00') AND TIME('18:00:00') 
GROUP BY DATE(date)

Answer 2

SELECT `date`, 
       Count(*) 
FROM   table_name tn 
WHERE  tn.date >= Timestampadd(hour, 9, Curdate()) 
       AND tn.date <= Timestampadd(hour, 18, Curdate()) 
GROUP  BY `date`
