DATE_FORMAT(date,format) 
Formats the date value according to the format string. 
The following specifiers may be used in the format string. As of MySQL 3.23, the “%” character is required before format specifier characters. In earlier versions of MySQL, “%” was optional.

The %v, %V, %x, and %X format specifiers are available as of MySQL 3.23.8. %f is available as of MySQL 4.1.1. 
Ranges for the month and day specifiers begin with zero due to the fact that MySQL permits the storing of incomplete dates such as '2014-00-00' (as of MySQL 3.23). 
As of MySQL 4.1.21, the language used for day and month names and abbreviations is controlled by the value of the lc_time_names system variable (Section 9.8, “MySQL Server Locale Support”). 
As of MySQL 4.1.23, DATE_FORMAT() returns a string with a character set and collation given by character_set_connection and collation_connection so that it can return month and weekday names containing non-ASCII characters. Before 4.1.23, the return value is a binary string. 
mysql> SELECT DATE_FORMAT('2009-10-04 22:23:00', '%W %M %Y');
    -> 'Sunday October 2009'
mysql> SELECT DATE_FORMAT('2007-10-04 22:23:00', '%H:%i:%s');
    -> '22:23:00'
mysql> SELECT DATE_FORMAT('1900-10-04 22:23:00',
  ->         '%D %y %a %d %m %b %j');
    -> '4th 00 Thu 04 10 Oct 277'
mysql> SELECT DATE_FORMAT('1997-10-04 22:23:00',
  ->         '%H %k %I %r %T %S %w');
    -> '22 22 10 10:23:00 PM 22:23:00 00 6'
mysql> SELECT DATE_FORMAT('1999-01-01', '%X %V');
    -> '1998 52'
mysql> SELECT DATE_FORMAT('2006-06-00', '%d');
    -> '00'
