DATE_FORMAT(

string.
The following specifiers may be used in the format

” 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.
