(1055, "Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'XX' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by")mysql

MySQL 5.7和up实现了对功能依赖的检测。若是启用了only_full_group_by SQL模式(在默认状况下是这样)，那么MySQL就会拒绝选择列表、条件或顺序列表引用的查询，这些查询将引用组中未命名的非聚合列，而不是在功能上依赖于它们sql

解决方法一：session

　　取消/etc/my.cnf里的sql_modethis

解决方法二：（亲测有效）spa

# 一、 mysql> set global sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';

# 二、 mysql> set session sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';

# 三、 set @@sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
