MySQL报错"Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column"通常是因为在SQL查询中使用了GROUP BY子句,但SELECT列表中的某些列既没有被包含在GROUP BY子句中,也没有被聚合函数(如SUM, AVG, MAX, MIN, COUNT等)处理。 原因分析 在MySQL 5.7及更高版本中,默认启用了...
但当mysql的版本高于5.7时,在执行group by时,select的字段不属于group by的字段的话,就会报错。报错信息如下: 1055- Expression #1of SELECT list is notinGROUP BY clause and contains nonaggregated column ‘数据库名.表名.字段名’whichis not functionally dependent on columnsinGROUP BY clause; this is in...

1055 - Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column。 这种主要是原因是在进行数据库版本升级,但是你的sql语句没有进行改动导致的。 一般不修改代码,修改数据库配置文件就可以解决。 解决办法如下: 1、找到mysql数据的安装路径。
1. 方法一、把你要分组的字段设置成设成primary key 或者 unique NOT NULL。 2.方法二、关闭sql_mode=ONLY_FULL_GROUP_BY # 查询当前设置 SELECT@@GLOBAL.sql_mode; # 关闭--对于后来新建的有效 set@@sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO...
