The locale indicated by the
lc_time_names
system variable
controls the language used to display day and month names and
abbreviations. This variable affects the output from the
DATE_FORMAT()
,
DAYNAME()
, and
MONTHNAME()
functions.
The lc_time_names
value does not
affect the result from FORMAT()
,
but this function takes an optional third parameter that enables a
locale to be specified to be used for the result number's decimal
point, thousands separator, and grouping between separators.
Allowable locale values are the same as the legal values for the
lc_time_names
system variable.
Locale names have language and region subtags listed by IANA
(http://www.iana.org/assignments/language-subtag-registry)
such as 'ja_JP'
or 'pt_BR'
.
The default value is 'en_US'
regardless of your
system's locale setting, but you can set the value at server
startup or set the GLOBAL
value if you have the
SUPER
privilege. Any client can
examine the value of
lc_time_names
or set its
SESSION
value to affect the locale for its own
connection.
