1運行sql命令時若出現(xiàn)如下錯誤：
[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
解決辦法烛卧，執(zhí)行下面三句命令：
show variables like "sql_mode";
set sql_mode='';
set sql_mode='NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES';
