MYSQL ERR 1055 ONLY_FULL_GROUP_BY 错误解决

MYSQL ERR 1055 错误信息

[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

初步判定是数据库的SQL_MODE配置错误，具体可以通过这个SQL来查看：

select @@sql_mode;

如果有配置ONLY_FULL_GROUP_BY的配置项。可以在MY.CNF重新配置sql_mode来解决。

把SQL_MODE中的ONLY_FULL_GROUP_BY配置项删除掉，重启服务器即可。

如果没有sql_mode的配置可以使用以下配置信息：

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