MySQL 根据年、月、日、时、分、秒分组查询

示例：

代码：

SELECT 
	create_time,
  YEAR ( create_time ),
	MONTH ( create_time ),
	DAY ( create_time ),
	HOUR(create_time),
	MINUTE(create_time),
	SECOND(create_time)
FROM
	sys_role_menu 
GROUP BY
	YEAR ( create_time ),
	MONTH ( create_time ),
	DAY (create_time),
	HOUR(create_time),
	MINUTE(create_time),
	SECOND(create_time)
