如何在Oracle中编写SQL来显示我的案例中的数据？

我有一张这样的桌子-

create table tbl1 
(
id number,
role number
);


insert into tbl1 values (1, 1);
insert into tbl1 values (2, 3);
insert into tbl1 values (1, 3);


create table tbl2
(
role number,
meaning varchar(50)
);

insert into tbl2 values (1, 'changing data');
insert into tbl2 values (2, 'move file');
insert into tbl2 values (3, 'dance');

我希望sql结果如下所示-

id     role_meaning      is_permitted
1      changing data     yes
1      move file         no
1      dance             yes
2      changing data     no
2      move file         no
2      dance             yes     

请帮忙，我怎么做？我尝试过几种方法，但不确定如何做到这一点。

您可以在这里使用

查询1：

select tbl1.id,
tbl2.meaning,
case when tbl1.role is NULL then 'no' else 'yes' end is_permitted
from tbl1 
partition by (id) right outer join tbl2
on tbl1.role = tbl2.role
order by tbl1.id, tbl2.role

| ID |       MEANING | IS_PERMITTED |
|----|---------------|--------------|
|  1 | changing data |          yes |
|  1 |     move file |           no |
|  1 |         dance |          yes |
|  2 | changing data |           no |
|  2 |     move file |           no |
|  2 |         dance |          yes |

：

select tbl1.id,
tbl2.meaning,
case when tbl1.role is NULL then 'no' else 'yes' end is_permitted
from tbl1 
partition by (id) right outer join tbl2
on tbl1.role = tbl2.role
order by tbl1.id, tbl2.role

| ID |       MEANING | IS_PERMITTED |
|----|---------------|--------------|
|  1 | changing data |          yes |
|  1 |     move file |           no |
|  1 |         dance |          yes |
|  2 | changing data |           no |
|  2 |     move file |           no |
|  2 |         dance |          yes |

您的

列中的数据从哪里来？表
tbl1
和
tbl2
似乎没有。您好，这应该从“tbl1”表中确定（如果值为1，则为是，如果表中不存在，则为否）
