一、异常摘要
Error querying database. Cause: java.sql.SQLSyntaxErrorException: Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'local-bdccg.da.id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
二、原因分析
sql_mode=only_full_group_by:group by聚合操作,select中的列,需要在group by中出现,或者来源于聚合函数的值,否则异常
三、解决办法
3.1 方法一
1 # 查看当前的sql_mode 2 SELECT @@global.sql_mode 3 SHOW VARIABLES LIKE '%sql_mode%'; 4 5 # 修改sql_mode 6 SET @@global.sql_mode ='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
3.2 方法二
修改my.ini配置文件
1 [client] 2 port=3306 3 default-character-set=utf8 4 5 [mysqld] 6 # 设置为自己MYSQL的安装目录 7 basedir=D:\\software\\mysql-5.7.39 8 # 设置为MYSQL的数据目录 9 datadir=D:\\software\\mysql-5.7.39\\data 10 port=3306 11 character_set_server=utf8 12 sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION 13 #开启查询缓存 14 explicit_defaults_for_timestamp=true 15 skip-grant-tables 16 #默认引擎 17 default-storage-engine=InnoDB
启动mysql服务提示:
删除mysql的datadir目录下的ib_logfile0、ib_logfile1
重新启动mysql服务,提示:
mysql 配置文件my.ini的basedir和datadir目录路径单斜杠修改为双斜杠,保存后,启动mysql服务即可:
