MySQL常见错误

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：在my.ini文件中加 sql_mode='NO_ENGINE_SUBSTITUTION' 重启服务即可。
