mysql5.7执行sql语句成功,但是报错Err:1055
无论执行什么sql语句都报错:
[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
试了好多方法,最后通过修改my.ini文件彻底解决:
1,运行
SHOW VARIABLES LIKE "sql_mode";
结果: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
2,将上述结果的ONLY_FULL_GROUP_BY去掉,赋值到my.ini文件下的[mysqld]下的sql_mode
即:sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SU
重启服务
再次运行,成功!
