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

 

升级之后,执行sql语句,结果报[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 这个错误,语句虽然执行成功了,但是出现这个错误。

于是百度了一下这个错误的解决办法:

查看下SQL的模式

SHOW VARIABLES LIKE '%sql_mode%';  

ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

的确是存在 ONLY_FULL_GROUP_BY.

修改sql_mode的值:

set sql_mode = '';
set sql_mode = 'NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES';

再次执行刚才的语句,就OK了。

或者:

解决方案:

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

 

或者:

在my.ini中加入如下代码:

[mysqld]

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

重启服务即可。
