MySQL Err 1055 解决办法

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

解决

去掉sql_mode中的ONLY_FULL_GROUP_BY。

查询 SQL 模式

查询全局SQL模式：

SELECT @@global.sql_mode;

输出：

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

设置 SQL 模式

去掉sql_mode中的ONLY_FULL_GROUP_BY。

SET @@global.sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));
