“select list is not in group by”错误是MySQL在启用了ONLY_FULL_GROUP_BY SQL模式时,对GROUP BY子句执行更严格的语义检查所产生的。这个错误表明,在SELECT列表中使用的列没有出现在GROUP BY子句中,同时这些列也不是聚合函数的一部分。根据SQL/92标准,如果GROUP BY子句存在,SELECT列表中的每个列都必须是GROUP ...
报错如下: Expression #2 ofSELECT list is not in GROUP BY clause and contains nonaggregatedcolumn ‘sss.month_id’ which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by 问题出现的原因:MySQL5.7.5及以上功能依赖检测功能。如果启用...

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...
产生原因说是,在MySQL数据库版本为5.7以上的版本,默认开启了 ONLY_FULL_GROUP_BY SQL模式,在此模式下,对于group by操作,如果在select语句中的查询列没有在group by中出现,那么这个SQL就是非法的,因为列不在group by语句中,所以设置了sql_mode=only_full_group_by的数据库,在使用group by时就会报错。
1055(42000): SELECT list is not in GROUP BY clause and contains nonaggregated column 原因与解决方案 该报错主要是因为sql_mode参数被修改导致: 原因一:用户修改sql_mode参数导致GROUP BY的语法不合规 原因:用户修改了sql_mode参数,添加了ONLY_FULL_GROUP_BY条件,导致GROUP BY的语法不符...
简介:MySQL5.7.5后only_full_group_by成为sql_mode的默认选项之一,这可能导致一些sql语句失效。 一、原因 MySQL5.7.5后only_full_group_by成为sql_mode的默认选项之一,这可能导致一些sql语句失效。 二、解决办法 1、命令行打开mysql.cnf,默认路径为/etc/mysql/conf.d/mysql.cnf,如果找不到可以使用whereis进行查...
Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column xxxxx 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;...

mysql使用group by查询报错SELECT list is not in GROUP BY clause and contains nonaggregated column...原因及解决方案 官方解释:ONLY_FULL_GROUP_BY是MySQL数据库提供的一个sql_mode, 通过这个 sql_mode 来保证, SQL语句 “分组求最值” 合法性的检查. 这种模式采用了与 Oracle、DB2 等数据库的处理方式。即...
