Php 使用具有多个时间范围的单个查询从两个表中获取
我有两个表Php 使用具有多个时间范围的单个查询从两个表中获取,php,mysql,Php,Mysql,我有两个表report和report1 range count countapps 06:31:00-07:30:00 2 count from report1 5:30:00-6:30:00 2 count from report1 报告表格 id user dt 1 a 2014-06-23 05:30:00 2 b 2014-06-23 06:30:00 3

如何在单个查询中做到这一点我想我应该将当前查询用作子查询，并将其与另一个表连接起来（因为当前查询生成另一个表所键入的时间范围名称） 类似这样的情况，尽管您也需要将日期添加到子查询中（不确定要加入的日期-所有记录是否来自同一日期？）- 编辑-有点笨重，但想想这样的东西就可以了：-
SELECT sub0.TimeRange, sub0.number, COUNT(*) AS countapps
FROM
(
SELECT
CASE
WHEN DATE_FORMAT(dt,'%H:%i:%s') BETWEEN '05:30:00' and '06:30:00'
THEN STR_TO_DATE(CONCAT(CURDATE(), ' ', '05:30:00'), '%Y-%m-%d %H:%i:%s')
WHEN DATE_FORMAT(dt,'%H:%i:%s') BETWEEN '06:31:00' and '07:30:00'
THEN STR_TO_DATE(CONCAT(CURDATE(), ' ', '06:31:00'), '%Y-%m-%d %H:%i:%s')
WHEN DATE_FORMAT(dt,'%H:%i:%s') BETWEEN '07:31:00' and '08:30:00'
THEN STR_TO_DATE(CONCAT(CURDATE(), ' ', '07:30:00'), '%Y-%m-%d %H:%i:%s')
ELSE NULL

GROUP BY StartRange, EndRange, TimeRange
HAVING TimeRange IS NOT NULL
) sub0
LEFT OUTER JOIN report1
ON report1.dt BETWEEN sub0.StartRange AND sub0.EndRange
GROUP BY sub0.TimeRange, sub0.number
您希望如何更详细地加入report1？日期和时间何时与日期和开始时间匹配？或者时间是否在时间范围内？只需在每一行中添加此
和DATE_格式（dt，%Y:%m:%d'）=DATE（CURDATE（））
