MYSQL---Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated column

--數據庫中插入數據或執行sql語句時一直報下面這個錯誤：
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

 

緣由：這是數據庫的sql_mode設置的有問題。Mysql能夠支持不一樣的SQL模式，不一樣的SQL模式會有不一樣的語法，執行不一樣的數據校驗簡查。

首先，能夠先查看一下數據庫如今的sql_mode的值，sql語句爲：

select version(), @@sql_mode;

獲取結果可能以下，不一樣的設置查詢出來的有區別：

 

而後能夠使用以下語句，去設置本身須要的sql_mode.

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

2、嘗試第二種方案

一、查看sql_mode

select @@sql_mode
查詢出來的值爲：

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

二、去掉ONLY_FULL_GROUP_BY，從新設置值。

set @@sql_mode =‘STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION‘;
三、上面是改變了全局sql_mode，對於新建的數據庫有效。對於已存在的數據庫，則須要在對應的數據下執行：

set sql_mode =‘STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION‘;或者：在my.cnf 裏面設置sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'在sql_mode 中去掉only_full_group_by 傳送門：https://blog.csdn.net/u012259256/article/details/56482218
