If the ONLY_FULL_GROUP_BY SQL mode is enabled (which it is by default), MySQL rejects queries for which the select list, HAVING condition, or ORDER BY list refer to nonaggregated columns that are neither named in the GROUP BY clause nor are functionally dependent on them.
MySQL also permits a nonaggregate column not named in a GROUP BY clause when SQL ONLY_FULL_GROUP_BY mode is enabled, provided that this column is limited to a single value

or in the default_ID_file). If the filename does not end in .pub this is added. If the filename
is omitted, the default_ID_file is used.
