Ordering a MySQL query result based on date

I have a bunch of entries in a database, which I want to sort via date, but the date format looks like this Y-m-d g:i:s, how could I search the database via the dat开发者_如何转开发e, and not date time?

---

If it's a datetime field do this for ordering

ORDER BY date_field ASC

For searching do

WHERE DATE(date_field) = '2010-05-08'

If it's a varchar type field try looking at STR_TO_DATE (link)

---

select * form table where date(datetime) = '2010-05-08'

---

That's easy. Convert your dates into proper format first, which is Y-m-d h:i:s

---

here is an example

$sql="SELECT cast(".$date." AS datetime) as sortdate FROM table order by sortdate ASC";

or

$sql="SELECT cast(DateColumnName AS datetime) as sortdate FROM table order by sortdate ASC";

---

You can do:

ORDER BY UNIX_TIMESTAMP(your_date)

your_date date needs to be converted first to Y-m-d h:i:s
