程序报mysql相关错误:
[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
解决办法:删掉配置文件中 sql_mode 里配置 ONLY_FULL_GROUP_BY,重启 mysql 即可解决。
