Mysql 连接(left join, right join, inner join ,full join)

2017-03-17 16:08 621 查看
在mysql的数据查询过程中,我们不仅仅会遇到单表查询的情况,特别在软件开发的过程中我们很多情况下是关联其他表查询相关的数据。
在此我们将学习MySQL 的 JOIN 在两个或多个表中查询数据。可以在SELECT, UPDATE 和 DELETE 语句中使用 Mysql 的 JOIN 来联合多表查询。
JOIN 按照功能大致分为如下三类:
INNER JOIN(内连接,或等值连接):获取两个表中字段匹配关系的记录。

LEFT JOIN(左连接):获取左表所有记录,即使右表没有对应匹配的记录。

RIGHT JOIN(右连接): 与 LEFT JOIN 相反,用于获取右表所有记录,即使左表没有对应匹配的记录。

现在我们使用inner join 查询
select  * from class1 inner join class2 on class1.id=class2.id; #查询两个表中ID一样的
或者 select   * from  class1,class2 where class1.id=class2.id
执行结果:
select   * from  class1,class2 where class1.id=class2.id;
+-----+--------+--------+-----+--------+--------+
| id  | name   | class  | id  | name   | class  |

由于表中的数据量大,所以只截取了一部分。由此看出inner join 是根据两张表或者
多张表满足一定关系求相关的交集。
left join 实践 left join 根据左边的表查询关系和右边的关系一样的,即使右边的表没有数据
mysql> select * from class1  left  join class2 on class1.id=class2.id;
+-----+--------+--------+------+--------+-------+
| id  | name   | class  | id   | name   | class |

|  37 | linux  | 66     |   37 |        |       |

根据结果可以发现 右边的部分表是没有数据的但是还是可以匹配到,所以left join是根据左边的表
匹配相关内容。
right join 与 LEFT JOIN 相反,用于获取右表所有记录,即使左表没有对应匹配的记录。
select * from class1  right  join class2 on class1.id=class2.id;

还有一种是full join,mysql不支持,但是我们可以将左连接和右连接结合,这样既可达到此类的效果
示例:
select * from class1  left  join class2 on class1.id=class2.id  UNION select * from class1
right  join class2 on class1.id=class2.id;
id   | name   | class  | id   | name   | class |
