在sql / php中选择日期和日期（其他格式）之间的所有内容

Question

This is the format in the column "date":

2011-08-03 13:36:19

What i wish to do is make a sql query where it selects all entrys between two dates.

My two dates comes from a datepicker:

from 2011-09-20 to 2011-09-25

Now I cant do WHERE date BETWEEN '2011-09-20' AND '2011-09-25'

Because there is also time in the column date, as you can see above.

So how can i do this? Can i do BETWEEN 2011-09-20 00:00:00 AND 2011-09-25 00:00:00 ?

Answer 1

如果你想要包括25日，你必须去

BETWEEN '2011-09-20 00:00:00' AND '2011-09-25 23:59:59'

Answer 2

You answered your own question: zero fill the time. It makes sense, since 00:00:00 is midnight, and indicates the moment one day switches to the next.

Answer 3

Those two conditions are logically equivalent (although your second one has a syntax error as you are missing the single quotes).

You probably mean to add the time to the end date. You'll want to add 23:59:59 to denote the end of the day so it includes all times during that day.

You can do so by appending your end date string (assuming it is POST data from a form with an input name of end_date).

$end_date = $_POST['end_date'] . ' 23:59:59';
