MySql query to select records with a particular date

Question

so right now I'm storing a the date of each search done on my site like this

2011-06-07 21:44:01

now I'd like to execute a query to select all values where the date is equal to whatever, but only the year / month and day are taken into account, so it would be like

mysql_query("SELECT tag from tags WHERE date = '2011-06-07'");

but it shouldn't take into account the exact time (hour minute seconds), is there any way to do this?

Answer 1

You could use the DATE() function.

SELECT `tag`
  FROM `tags`
 WHERE DATE(`date`) = '2011-06-07'

However, for better performance you could use...

  WHERE `date` 
BETWEEN '2011-06-07'
    AND '2011-06-07 23:59:59'

Answer 2

This should work:

mysql_query("SELECT tag from tags WHERE date LIKE '2011-06-07%'");

Answer 3

mysql_query("SELECT tag from tags WHERE DATE(`date`) = '2011-06-07'");
