[Err] 1055 - Expression #1 of ORDER BY clause is not in GROUP BY clause 的问题 MySQL

Posted 2021-02-16 疯疯敲代码

问题：[Err] 1055 - Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated column \'information_schema.PROFILING.SEQ\' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

 

 

解决方案：

select version(),
@@sql_mode;SET sql_mode=(SELECT REPLACE(@@sql_mode,\'ONLY_FULL_GROUP_BY\',\'\'));

 

 

 

 

完美的解决方案是：

 

1 show variables like "sql_mode";
2 
3 set sql_mode=\'\';
4 set sql_mode=\'NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES\';
