问题

        SELECT list is not in GROUP BY clause and contains nonaggregated column \\'testdb.testtables.plat_id\\' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

查看数据库是否设置了only_full_group_by属性，该属性会导致上述问题，需要去掉
select @@sql_mode;

修改my.cnf配置文件，添加如下
[mysqld]
sql_mode=STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
