sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION 2、写sql修改 SELECT @@sql_mode; SET SESSION sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY,','')); 3、在jdbc连接中指定sql_mode方式 url: jdbc:mysql://127.0.0.1:330...
重新设置,去掉ONLY_FULL_GROUP_BY即可: SETGLOBAL sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'; 当然,如果想去掉所有限制也是可以的: SETGLOBAL sql_mode=''; 这个方法的好处是不用重启MySQL生效(需要注意的是在当前...
MySQL implements detection of functional dependence. If theONLY_FULL_GROUP_BYSQL mode is enabled (which it is by default), MySQL rejects queries for which the select list, HAVING condition, or ORDER BY list refer to nonaggregated columns that are neither named in the GROUP BY clause nor are ...

与mysql中的sql_mode=only_full_group_by不兼容 是指在MySQL数据库中,当设置sql_mode为only_full_group_by时,会导致某些查询语句无法执行或者结果不符合预期。 sql_mode是MySQL中的一个系统变量,用于控制数据库的行为。当设置sql_mode为only_full_group_by时,MySQL会对GROUP BY语句进行严格的检查,要求SELECT语...
“错误代码:1055。SELECT列表的表达式#1不在GROUP BY子句中,并且包含非聚合列’test.t_iov_help_feedback.ID’,它在功能上不依赖于GROUP BY子句中的列; 这与sql_mode = only_full_group_by不兼容” 原因分析: 一、原理层面 这个错误发生在mysql5.7.5版本及以上版本会出现的问题: ...
select @@global.sql_mode;这个时候，就会返回得到以下的信息：（不同电脑返回的信息可能不同）ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION 如果里面包含 ONLY_FULL_GROUP_BY，那么就重新设置，在数据库中输入以下代码，去掉ONLY_FULL_GROUP_BY即可：SET GLOBAL sql_mode='STRICT_TRANS_TABLES,...
对于group by 的这种聚合操作,如果在select 中的列,没有在group by 中出现,那么这个SQL是不合法的,因为列不在group by的从句中,所以对于设置了这个mode的数据库,在使用group by 的时候,就要用MAX(),SUM(),ANT_VALUE()的这种聚合函数,才能完成GROUP BY 的聚合操作。
ERROR 1055 (42000): Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'imooc.tdb_goods.goods_id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by修改...
