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.
%aSun..Sat)%bJan..Dec)%c0..12)%D0th, 1st, 2nd, 3rd, …)%d00..31)%e0..31)%f000000..999999)%H00..23)%h01..12)%I01..12)%i00..59)%j001..366)%k0..23)%l1..12)%MJanuary..December)%m00..12)%pAM or PM %rhh:mm:ss followed by AM or PM)%S00..59)%s00..59)%Thh:mm:ss)%U00..53), where Sunday is the first day of the week%u00..53), where Monday is the first day of the week%V01..53), where Sunday is the first day of the week; used with %X %v01..53), where Monday is the first day of the week; used with %x %WSunday..Saturday)%w0=Sunday..6=Saturday)%X%V %x%v %Y%y%%%” character%xx, for any “x” not listed aboveThe %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.
