用到GROUP BY 语句查询时出现 which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by错误 解决方法 :执行SET GLOBAL sql_mode = ''; 把sql_mode 改成非only_full_group_by模式. 然后,重新连接数据库,再执行含有group by语句的查询语句:…

这会导致select中只能出现group by后面出现的表的字段. 其实如果使用其他表的字段,聚合函数对无法对应其他表的字段. 建议放在子查询里. 如果想打破这个规则,可以设置sql_mode变量,将ONLY_FULL_GROUP_BY去掉即可.…
