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

問題：[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

解決方案：

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

完美的解決方案是：

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