最近在部署项目之后,运行出现报错: Expression #1of SELECTlistis not in GROUP BY clause and contains nonaggregated column ‘grades.order_id’ which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by 问题描述 字面意思理解: SELECT 列表...
Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggre 原因分析mysql 5.7默认启用ONLY_FULL_GROUP_BY特性,即:对于GROUP BY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从句中,也就是说查出来的列必须在group by后面出现否则就会报错,...

因为执行sql_make_group语句时会把两行纪录id=1和id=2两行记录合并成一行,但是搜索引擎不知道该返回哪一条,所以报错。 3、原因总结 MySQL 5.7.5后only_full_group_by成为sql_mode的默认选项之一,这可能导致一些sql语句失效。我们只需要把only_full_group_by从sql_mode中移除即可...
