MySQL Error

Expression #2 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'blinkenlights.wiki.date' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
Querystring

			SELECT DISTINCT name, date, MAX(rev)
			FROM wiki
			WHERE category = 'IDE'
			GROUP BY name
