我已经爬过任何类似的查询，但找不到确切的解决方案。

如有任何帮助，我们将不胜感激。谢谢!

这假设 sTime 是您显示的格式的字符串。

SELECT name, date, IFNULL(intime, '') `In Time`, IFNULL(outtime, '') `Out Time`
FROM (
    SELECT name, sdate AS date, 
        MIN(IF(SUBSTRING_INDEX(sTime, ' ', -2) BETWEEN '7:00:00 AM' AND '8:30:00 AM', 
                SUBSTRING_INDEX(SUBSTRING_INDEX(sTime, ' ', 2), ' ', -1), 
                NULL)) AS intime,
        MAX(IF(SUBSTRING_INDEX(sTime, ' ', -2) BETWEEN '4:00:00 PM' AND '5:15:00 PM', 
                SUBSTRING_INDEX(SUBSTRING_INDEX(sTime, ' ', 2), ' ', -1), 

                NULL)) AS outtime
    FROM YourTable
    GROUP BY name, sdate
    HAVING intime IS NOT NULL OR outtime IS NOT NULL
    ) AS x
ORDER BY intime IS NULL, intime, outtime
