mysql 报错

SQLSTATE[42000]: Syntax error or access violation: 1055 Expression #6 of SELECT list is not in GROUP BY clause and contains nonaggregated column ‘field_name’ which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

原因

mysql 5.7 sql_group 默认按sql标准了
可以设置sql_mode 去掉
SELECT @@GLOBAL.sql_mode;
SELECT @@SESSION.sql_mode;
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’;
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’;
