如何根据php中的数据库字段值对天数进行分组

我保持着公司的工作时间。如何根据工作时间分组工作日

我想要像这样的输出

Sunday, Saturday 00:00:00 to  00:00:00
Monday, Tuesday, Wednesday, Thursday 10:00:00 to 18:00:00
Friday 10:00:00 to 13:00:00

查询输出：

我该怎么做呢？

你可以这样试试

SELECT GROUP_CONCAT(day) days, CONCAT(from_time, ' to ', to_time) times
FROM yourTable
GROUP BY from_time, to_time

SELECT 
GROUP_CONCAT(DAY) AS 'DAY', 
FROM_TIME AS 'IN'
TO_TIME AS 'OUT'

FROM TABLE_NAME

GROUP BY FROM_TIME, TO_TIME 
ORDER BY DAY 

你可以这样试试

SELECT 
GROUP_CONCAT(DAY) AS 'DAY', 
FROM_TIME AS 'IN'
TO_TIME AS 'OUT'

FROM TABLE_NAME

GROUP BY FROM_TIME, TO_TIME 
ORDER BY DAY
