I have a column of type "datetime" with values like 2009-10-20 10:00:00

I would like to extract date from datetime and write a query like:

SELECT * FROM 
data 
WHERE datetime = '2009-10-20' 
ORDER BY datetime DESC

Is the following the best way to do it?

SELECT * FROM 
data 
WHERE datetime BETWEEN('2009-10-20 00:00:00' AND '2009-10-20 23:59:59')
ORDER BY datetime DESC

This however returns an empty resultset. Any suggestions?

You can use MySQL's DATE() function:

WHERE DATE(datetime) = '2009-10-20'

You could also try this:

WHERE datetime LIKE '2009-10-20%'

See this answer for info on the performance implications of using LIKE.
