mysql8：Expression #12 of SELECT list is not in GROUP BY clause and contains nonaggregated

异常信息：

• Expression #12 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'emms.D.NAME' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode

原因：

• mysql8聚合查询出现这样的报错是因为mysql设定的mode含有 ONLY_FULL_GROUP_BY
• MySQL 5.7.5及以上功能依赖检测功能。如果启用了ONLY_FULL_GROUP_BY SQL模式（默认情况下），MySQL将拒绝选择列表，HAVING条件或ORDER BY列表的查询引用在GROUP BY子句中既未命名的非集合列，也不在功能上依赖于它们。（5.7.5之前，MySQL没有检测到功能依赖关系，默认情况下不启用ONLY_FULL_GROUP_BY。有关5.7.5之前的行为的说明，请参见“MySQL 5.6参考手册”。）

解决方法：

• ps：编辑my.cnf，重新设置sql_mode，最后重启mysql服务即可
• vim /etc/my.cnf

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION
