select * from s_student group by address > 1055 - Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'java83.s_student.stuno' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by这段查询语句为什么会报错

这段查询语句会报错是因为在 SQL 的严格模式下，GROUP BY 语句需要将所有未聚合的列都包含在 GROUP BY 子句中。而这段查询语句中，SELECT 列表中包含了未聚合的列 stuno，但是却没有在 GROUP BY 子句中出现，因此会报错。

你可以将查询语句修改为以下形式来避免报错：

SELECT * FROM s_student GROUP BY address, stuno;

这样就将未聚合的列 stuno 也加入了 GROUP BY 子句中，从而符合 SQL 严格模式的要求。
