1055 - Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'queqiao.a.iid' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
解决办法：修改my.cnf文件
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
service mysqld restart
