Select... where time between start and end
Select * from table where addtime> = '? Start ?? And addtime <= '? ?? ';
I only checked the data of the day. The upstairs writing method found all the data in the database during this time period.
Select... where time between start and end
How to write data on the day of "time?
The start time and end time are only hours, minutes, and seconds. how can this problem be solved?

DATE_FORMAT () is the time format you want to query. However, the efficiency will be low.

$ Starttime = '17: 25: 00 ';
$ Endtime = '17: 35: 00 ';
$ SQL = "select * from table where addtime> = '". date ('Y-m-D '). ''. $ starttime. "'and addtime <= '". date ('Y-m-D '). ''. $ endtime. "'";
The original landlord's date and time are stored in two fields, then you have to use date + time to form a new value, with date + time> = '? Start date ?? 'And date + time <= '? Start date ?? '
Select * from table where addtime> = '? Start ?? And addtime <= '? ?? ';

I am very grateful to the moderator. I am already OK. which books or Baidu can I find for this knowledge? I just started to learn about it. I only talk about basic queries for the books and videos I am looking, insert and delete operations. no further details are available.
