  • 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.

    SpecifierDescription%aAbbreviated weekday name (Sun..Sat)%bAbbreviated month name (Jan..Dec)%cMonth, numeric (0..12)%DDay of the month with English suffix (0th, 1st, 2nd, 3rd, …)%dDay of the month, numeric (00..31)%eDay of the month, numeric (0..31)%fMicroseconds (000000..999999)%HHour (00..23)%hHour (01..12)%IHour (01..12)%iMinutes, numeric (00..59)%jDay of year (001..366)%kHour (0..23)%lHour (1..12)%MMonth name (January..December)%mMonth, numeric (00..12)%pAM or PM %rTime, 12-hour (hh:mm:ss followed by AM or PM)%SSeconds (00..59)%sSeconds (00..59)%TTime, 24-hour (hh:mm:ss)%UWeek (00..53), where Sunday is the first day of the week%uWeek (00..53), where Monday is the first day of the week%VWeek (01..53), where Sunday is the first day of the week; used with %X %vWeek (01..53), where Monday is the first day of the week; used with %x %WWeekday name (Sunday..Saturday)%wDay of the week (0=Sunday..6=Saturday)%XYear for the week where Sunday is the first day of the week, numeric, four digits; used with %V %xYear for the week, where Monday is the first day of the week, numeric, four digits; used with %v %YYear, numeric, four digits%yYear, numeric (two digits)%%A literal “%” character%xx, for any “x” not listed above

    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 (Section9.8, “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'
