mysql命令gruop by报错this is incompatible with sql_mode=only_full_group_by 看一下ONLY_FULL_GROUP_BY的意思是:对于GROUP BY聚合操作,如果在SELECT中的列,没有在GROUP BY中出现,那么这个SQL是不合法的,因为列不在GROUP BY从句中,也就是说查出来的列必须在group by后面出现否则就会报错,或者这个字段出现在聚...
ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION 修改方式,window编辑my.ini,Linux编辑my.cnf,将[mysqld]中的sql_mode的值删除ONLY_FULL_GROUP_BY,重启解决!
如果语法分析错误就会出现'You have an error in your SQL syntax'错误信息。 五、优化器 优化器的作用主要是执行计划生成,进行索引选择。 比如select * from user where name = '张三' and phone = ‘110’语句,并且name和phone各建立了索引。 优化器对执行方法进行判断。

版本中删除。延迟插入( DELAYED INSERT )和替换在MySQL 5.6中已弃用。在MySQL 8.0中,不支持DELAYED。服务器可以识别,但忽略DELAYED关键字,将插入处理视为非延迟插入,并生成ER__LEGACY_SYNTAX_CONVERTED 警告INSERT DELAYED is no longer supported. The statement was converted to INSERT。 可以将索引文件与...
