*	Add `columns_for_distinct` for MySQL 5.7 with ONLY_FULL_GROUP_BY	Ryuta Kamizono	2015-12-23	1	-0/+44
	In MySQL 5.7.5 and up, ONLY_FULL_GROUP_BY affects handling of queries that use DISTINCT and ORDER BY. It requires the ORDER BY columns in the select list for distinct queries, and requires that the ORDER BY include the distinct column. See https://dev.mysql.com/doc/refman/5.7/en/group-by-handling.html
