使用PFK的MySQL视图

我有以下表格：

Create table table1 (
 id Int UNSIGNED NOT NULL,
 name VARCHAR(255) NOT NULL, 
 Primary Key(id),
 Unique Key `name` (`name`)) 
ENGINE = InnoDB;

Create table table2 (
 id1 Int UNSIGNED NOT NULL,
 id2 Int UNSIGNED NOT NULL,
 Primary Key (id1,id2)) 
ENGINE = InnoDB;

Alter table table2 add Foreign Key (id1) references table1 (id) 
on delete  restrict on update  restrict;
Alter table table2 add Foreign Key (id2) references table1 (id) 
on delete  restrict on update  restrict;

---

我想问一下，是否有可能创建一种类型的

视图

，其中包含

表2

中提到的两个用户的姓名（来自

表1

）？感谢您的帮助。

这将在视图中放置ID在表2中的两列中的所有名称

CREATE VIEW MyView AS SELECT DISTINCT Name FROM Table1 
WHERE Id IN (SELECT DISTINCT Id1 FROM Table2 
UNION SELECT DISTINCT Id2 FROM Table2)

试试这个：

CREATE OR REPLACE VIEW ViewName
AS
SELECT
    T1.Name Name1, T2.Name Name2
FROM Table2 T
    JOIN Table1 T1
        ON T.Id1 = T1.Id
    JOIN Table1 T2
        ON T.Id2 = T2.Id;
