mysql遇见contains nonaggregated column 'information_schema.PROFILING.SEQ'异常

报错如下:
[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

问题出现的原因:
MySQL 5.7.5及以上功能依赖检测功能。如果启用了ONLY_FULL_GROUP_BY SQL模式(默认情况下),MySQL将拒绝选择列表,HAVING条件或ORDER BY列表的查询引用在GROUP BY子句中既未命名的非集合列,也不在功能上依赖于它们。(5.7.5之前,MySQL没有检测到功能依赖关系,默认情况下不启用ONLY_FULL_GROUP_BY。有关5.7.5之前的行为的说明,请参见“MySQL 5.6参考手册”。)

解决方案:
select @@global.sql_mode
SET sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY','')); ##当前session变量生效

SET global sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY','')); ##全局变量生效

 

SET sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));
set @@global.sql_mode 
='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
