[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%';
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',''));
[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。
