hi,

set LC_TIME_NAMES = 'de_AT';

select monthname('2016-02-01');

+-------------------------+

| monthname('2016-02-01') |

+-------------------------+

| Feber                   |

+-------------------------+

According to the Austrian Standards Institute 'Februar' should be used for the second month of the year, 'Feber' is an old form, only used in some parts of Austria.

Solution: replace 'Feber' with 'Februar' in sql_locale.cc :

I assign a patch for sql_locale.cc (branch 10.1 / 2016-04-16 11:30)

thanks
