mysql 创建表是出现

[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

原因

在MySQL5.7之后，sql_mode中默认存在ONLY_FULL_GROUP_BY，SQL语句未通过ONLY_FULL_GROUP_BY语义检查所以报错。

ONLY_FULL_GROUP_BY要求select语句中查询出来的列必须是明确的

解决方案

登录msyql

SELECT @@sql_mode

查询结果

ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION

修改my.conf

新增sql_mode,去掉

ONLY_FULL_GROUP_BY

修改内容如下

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION

重启即可
