项目数据突然查询不到：非代码问题 : sql_mode=only_full_group_by

报错：ERROR: Expression #2 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'patent_newt.t.company_persons' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

查看mysql的相关设置

使用命令

        select @@global.sql_mode; 可以查看全局sql_mode的值。

去掉ONLY_FULL_GROUP_BY：

set @@global.sql_mode=(select replace(@@global.sql_mode,'ONLY_FULL_GROUP_BY',''));

或者直接将查询全局sql_mode的值复制， 去掉ONLY_FULL_GROUP_BY，重新设置

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
