输出列顺序与输入不一致。比如 select * from id,age from t;
你输出的是
age | id
1 | 2
日期对比查询没有过

元数据合法性校验要考虑表、字段、和where条件中出现的元数据
元数据校验，比如不存在的表、字段、非法条件等。
大胸弟，一个帖子就可以了。
基础的日期比较查询，没有实现。比如select * from t where d >'2020-10-20';

求看一下date，谢谢
，和过date的同学交流了一下case,还多考虑到了一些，不知为啥
原因，会不会多检查了一些东西？

create table t_basic(id int, age int, name char, score float);
insert into t_basic values(1,1, 'a', 1.0);
insert into t_basic values(2,2, 'b', 2.0);
insert into t_basic values(4,4, 'c', 3.0);
insert into t_basic values(3,3, 'd', 4.0);
insert into t_basic values(5,5, 'e', 5.5);
insert into t_basic values(6,6, 'f', 6.6);
insert into t_basic values(7,7, 'g', 7.7);
select * from t_basic;
delete from t_basic where id=3;
select * from t_basic;
select * from t_basic where id=1;
select * from t_basic where id>=5;
select * from t_basic where age>1 and age<3;
select * from tbasic where tbasic.id=1 and t_basic.age=1;
select * from t_basic where id=1 and age=1;
select id, age, name, score from t_basic;
select tbasic.id, tbasic.age, tbasic.name, tbasic.score from t_basic;
select tbasic.id, tbasic.age, name from t_basic;
create index iid on tbasic (id);
select * from t_basic;
自己测试一下吧
谢谢！ 我们更改了一下代码，修复了以上问题，能否麻烦您帮我们再测一次，感激不尽。https://github.com/EmperorNiu/miniob

是不是头文件没有加
你好，我组的仓库地址是：https://github.com/xiaoyong-z/MiniOB
请问一下我们组的 agg 具体是挂在哪个 case 了呀？
谢谢你。

元数据校验包括 表、字段，还有where条件中的字段
drop 不存在的表，你测试一下
你们date是不是还没有做
现在加上，能麻烦在测试一下吗
是，是 date 没做的原因导致的吗？
date会测超过边界的情况吗 比如1970-1-1之前或者2038年2月之后
