大致错误如:ERROR 1055 (42000): Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'aaa.test.age' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by…

问题: 1055 - Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'cmp-31161029.t1.user_name' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by,…

解决方法1:SET sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));这种修改只是暂时性的,还是在 my.ini 文件中的sql-mode直接修改比较好. 解决方法2:使用语句查询 sql_mode 的值再到 my.ini(windows)或my.cnf(linux)配置文件找到 sql-mode 中注释(去掉)only_full_group_by,加上刚才查询到的值.…

问题原因: 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合函数里面. 探索原因: 查看mysql版本命令:select version(); 解决方法: 命令行输入 查看sql_model参数命令: SELECT @@GLOBAL.sql_mode; 设置成功后:退出重…
