sql_mode详解,bug修复!!!!!

本文主要是介绍sql_mode详解,bug修复!!!!!,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

处理MySQL数据库工作中遇到关于sql_mode的情况,特学习记录一下

废话不多说直接上错误提示,哈哈哈 bug开始!!!!

INSERT INTO mmb_user (openid,mobile,wxmobile,password,age,realnm,nicknm,avatar,height,weight,sex,country,province,city,invdcd,unionid,create_date,valid) VALUES (?,?, ?,?,             ?, ?,?,?,?,?,?,?, ?,?, ?, ?, now(), '1' ) on duplicate key update nicknm = ?,           openid = ?,avatar = ?, update_date = now(),valid = '1'
### Cause: java.sql.SQLSyntaxErrorException: In aggregated query without GROUP BY, expression #1 of SELECT list contains nonaggregated column 'ygdb.mmb.id'; this is incompatible with sql_mode=only_full_group_by
; bad SQL grammar []; nested exception is java.sql.SQLSyntaxErrorException: In aggregated query without GROUP BY, expression #1 of SELECT list contains nonaggregated column 'ygdb.mmb.id'; this is incompatible with sql_mode=only_full_group_by
In aggregated query without GROUP BY, expression #1 of SELECT list contains nonaggregated column 'ygdb.mmb.id'; this is incompatible with sql_mode=only_full_group_by

In aggregated query without GROUP BY, expression #1 of SELECT list contains nonaggregated column 'ygdb.mmb.id'; this is incompatible with sql_mode=only_full_group_by
在没有分组依据的聚合查询中,选择列表的表达式#1包含未聚合的列“ygdb.mmb.id”;这与sql\u mode=only\u full\u group\u by不兼容

意思就我的mysql语法校验规则不合规

那我就在mysql中执行,查看一下,确实有ONLY_FULL_GROUP_BY

①命令:select @@GLOBAL.sql_mode或者select @@SESSION.sql_mode 

②命令:SET sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY','')); 

③命令:select version(), @@sql_mode;

 

 完事!!!

 

 

 

 

 

下面还有惊喜哦,哈哈哈哈哈哈

 

 

 

 

 

在表里是没有问题了,但是在存储过程里面是对sql_mode无效的哦!!!需要在过程里面在加入这么一句就支持存储过程了,太棒了。bug修复完成!!!!

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