sql-mode="STRICT_ALL_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_ZERO_DATE,NO_ZERO_IN_DATE,NO_AUTO_CREATE_USER" 1 错误提示的意思,是上面的mode设置有问题,于是搜了一下博客,将其改为: [mysqld] sql_mode='NO_AUTO_VALUE_ON_ZERO,STRICT_TRANS_TABLES
解释error_for_division_by_zero是什么: error_for_division_by_zero是MySQL中的一个SQL模式(sql_mode)选项。当启用此模式时,如果尝试执行除以零的操作,MySQL将返回一个错误而不是NULL。这有助于及早发现潜在的计算错误。 说明MySQL中error_for_division_by_zero的默认行为: 在不同的MySQL版本中,error_for_divis...

This would essentially mean that current behavior of STRICT MODE + ERROR_FOR_DIVISION_BY_ZERO, NO_ZERO_DATE and NO_ZERO_IN_DATE = proposed behavior of STRICT MODE. See http://www.tocker.ca/2013/11/01/proposal-to-simplify-sql-modes.html for community feedback. This worklog deals with ...
NO_ZERO_IN_DATE 在严格模式下,不允许日期和月份为零 NO_ZERO_DATE 设置该值,mysql数据库不允许插入零日期,插入零日期会抛出错误而不是警告 ERROR_FOR_DIVISION_BY_ZERO 在insert或update过程中,如果数据被零除,则产生错误而非警告。如果未给出该模式,那么数据被零除时Mysql ...
sql_mode,会直接影响SQL语法支持和数据校验,它包含非常多的选项,其中5.7版本的默认值是“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”,一般不建议进行修改。

1、gourp by真的只能查询分组字段或者聚集字段? 首先准备两张表 t1为主表,t2根据classify_id关联 先执行一下简单分组,发现并没有出现问题 接着设置一下sql_mode set session sql_mode='ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USE...
针对MySQL分组不可用问题，我们有以下三种解决方法：1. 关闭ONLY_FULL_GROUP_BY选项 在MySQL中关闭ONLY_FULL_GROUP_BY选项，即可解决MySQL分组不可用问题。在MySQL配置文件中my.cnf中添加以下代码：[mysqld]sql_mode=“STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,...
