+## 6、唯一键
+
+unique key 
+可以有多个，
+允许数据为null, 可以有多个null，null不参与比较
+
+### 6.1、创建唯一键
+
+和主键类似
+
+- 直接在表字段后增加唯一键标识 `unique [key]`
+- 所有字段之后使用 `unique key(字段列表)`
+- 创建完表之后也可以增加唯一键
+
+```sql
+alter table 表名 add unique key(字段)
+
+-- 方式一：
+create table my_unique1(
+    id int primary key auto_increment,
+    username varchar(10) unique
+);
+
+-- 方式二：
+create table my_unique2(
+    id int primary key auto_increment,
+    username varchar(10),
+    unique key(username)
+);
+
+-- 方式三：
+create table my_unique3(
+    id int primary key auto_increment,
+    username varchar(10)
+);
+
+alter table my_unique3 add unique key(username);
+```
+
+### 6.2、查看唯一键
+
+```sql
+mysql> desc my_unique1;
++----------+-------------+------+-----+---------+----------------+
+| Field    | Type        | Null | Key | Default | Extra          |
++----------+-------------+------+-----+---------+----------------+
+| id       | int(11)     | NO   | PRI | NULL    | auto_increment |
+| username | varchar(10) | YES  | UNI | NULL    |                |
++----------+-------------+------+-----+---------+----------------+
+```
+
+不为空null的时候，不允许重复
+
+```sql
+-- 可以插入多个null
+insert into my_unique1 (username) values(null);
+insert into my_unique1 (username) values(null);
+
+-- 不为null时，不允许重复
+insert into my_unique1 (username) values('Tom');
+insert into my_unique1 (username) values('Tom');
+ERROR 1062 (23000): Duplicate entry 'Tom' for key 'username'
+```
+
+### 6.3、删除唯一键
+
+一个表中允许存在多个唯一键
+
+
+```sql
+alter table 表名 drop index 唯一键名字;
+
+
+alter table my_unique2 drop index username;
+
+mysql> desc my_unique2;
++----------+-------------+------+-----+---------+----------------+
+| Field    | Type        | Null | Key | Default | Extra          |
++----------+-------------+------+-----+---------+----------------+
+| id       | int(11)     | NO   | PRI | NULL    | auto_increment |
+| username | varchar(10) | YES  |     | NULL    |                |
++----------+-------------+------+-----+---------+----------------+
+```
+
+修改唯一键：先删除后增加
+
+### 6.4、复合唯一键
+
+可以使用多个字段来共同保证唯一性

+# 表关系
+
+表与表之间（实体）的关系
+
+## 一对一
+
+两张表使用相同的主键
+
+学生表
+```
+学生ID（PRI） 姓名 年龄 性别 籍贯 住址
+```
+常用的信息会经常查询，不常用的信息偶尔会用到
+
+解决方案：将两张表拆分
+常用的字段放一张表
+不常用的放一张表
+
+学生表（常用字段）
+```
+学生ID（PRI） 姓名 年龄 性别
+```
+
+学生表（不常用字段）
+```
+学生ID（PRI） 籍贯 住址
+```
+
+## 一对多(多对一)
+
+"多关系"的表中维护一个"一关系"的主键
+
+
+示例：
+
+父子关系：一个父亲有多个孩子，一个孩子只有一个父亲
+
+父亲表
+```
+父亲ID 年龄 身高
+F1
+F2
+```
+
+孩子表
+```
+孩子ID 年龄 身高 父亲ID
+K1              F1
+K2              F1
+```
+
+## 多对多
+
+一张表中的一条记录，在另一张表中可以匹配多条记录，反过来也一样
+
+需要通过第三张表来维护关系
+
+让中间表和对应的表行成多对一的关系；
+在“多表”中增加“一表”对应的主键字段
+
+例如：师生关系
+
+老师表
+```
+tid name  age gender
+T1  王老师 30    男
+T2  李老师 28    女
+```
+
+学生表
+```
+sid name age gender
+S1  张飞   18   男
+S2  关羽   16   男
+S3  刘备   19   男
+S4  小乔   16   女
+```
+
+老师学生关系表
+```
+id tid sid
+1   T1  S1
+2   T1  S2
+3   T2  S1
+4   T2  S3
+5   T2  S4
+6   T2  S5
+```
