Currently, I am doing mySQL queries as such selecting a unix time stamp from a database, like so:

SELECT 开发者_C百科DATE(FROM_UNIXTIME(time)) AS theday, COUNT(id) AS thecount FROM `table`
WHERE `time`>=UNIX_TIMESTAMP(CURRENT_DATE - > INTERVAL 14 DAY) 
GROUP BY theday 
ORDER by theday DESC

How would I go about doing a similar query but selecting a DATETIME format? Instead of a unix time stamp?

For example,

0000-00-00 00:00:00

I think MySql DATE_FORMAT will work for you.

mysql_query("SELECT DATE_FORMAT(time, '%Y-%m-%d %H:%i:%s') AS theday, COUNT(id) AS thecount FROM table WHERE time>=UNIX_TIMESTAMP(CURRENT_DATE - INTERVAL 14 DAY) GROUP BY theday ORDER by theday DESC");

Update:

Based on your comment, you can use DATE function to select date portion from your datetime field:

SELECT DATE(time)

Instead of:

SELECT DATE(FROM_UNIXTIME(time))

You can select your datetime field directly:

SELECT time
