5-1-1, 创建表时制定约束

语法:

create table 表名(

字段1 数据类型 not null

...

字段1 数据类型 not null));

# 创建表时指定字段id,name, job不能为空

主键是记录的唯一标识,一张表中有且只能有一个主键,且不能为null

5-3-1, 创建表时制定约束

语法:

create table 表名(

字段1 字段1数据类型 not null,

...

字段n 字段n数据类型 not null,

constraint 约束名称 primary key (字段x, ...));

# 创建表,并指定id列为主键,约束名称为aaa_primary_key 
mysql> create table aaa(
    -> id bigint not null,
    -> name varchar(20) not null,
    -> job varchar(20) not null,
    -> constraint aaa_primary_key primary key (id));

+-------+-------------+------+-----+---------+-------+
3 rows in set (0.00 sec)

5-3-4, 设置自增字段(auto_increment)

通过设置自增字段,在每次插入数据后,该字段自动加1;

默认从1开始自增

语法:

create table 表名(

字段1 字段1数据类型 not null auto_increment,

...

字段n 字段n数据类型 not null);

# 创建表bbb,并给主键id列设置自增
mysql> create table bbb(
    -> id bigint not null auto_increment,
    -> name varchar(50) not null,
    -> job varchar(50) not null,
    -> constraint bbb_pk primary key (id));
Query OK, 0 rows affected (0.34 sec)

mysql> insert into bbb (name, job) values ('zs', 'fsdafa');
Query OK, 1 row affected (0.15 sec)

mysql> select * from bbb;
+----+------+--------+
| id | name | job    |
+----+------+--------+
|  1 | zs   | fsdafa |
+----+------+--------+
1 row in set (0.00 sec)

修改自增字段的起始值

语法:alter table 表名 auto_increment = xxx

# 设置自增字段从100开始
mysql> alter table bbb auto_increment = 100;
Query OK, 0 rows affected (0.09 sec)
Records: 0  Duplicates: 0  Warnings: 0

mysql> insert into bbb (name, job) values ('zs', 'fsdafa');
Query OK, 1 row affected (0.05 sec)

mysql> select * from bbb;
+-----+------+--------+
| id  | name | job    |
+-----+------+--------+
|   1 | zs   | fsdafa |
| 100 | zs   | fsdafa |
+-----+------+--------+
2 rows in set (0.00 sec)

5-4, 外键约束(foreign key)

通过建立外键约束,可以建立表与表的联系,放置无效数据插入

一个表的外键通常来自另外一个表的主键

5-4-1, 创建表时制定约束

语法:

create table 表名(

字段1 字段1数据类型 not null,

...

字段n 字段n数据类型 not null,

constraint 约束名称 foreign key (字段x, ...) references 其他表(字段x, ...));

# 创建表bbb,并指定id列为外键,指向aaa表的id列
mysql> create table bbb(
    -> id bigint not null,
    -> gender varchar(20) not null,
    -> age int not null,
    -> constraint bbb_fk foreign key (id) references aaa(id));
Query OK, 0 rows affected (0.48 sec)

5-4-2, 修改外键约束

语法:

alter table 表名 add constraint 约束名称 foreign key (字段x, ...) references 其他表(字段x, ...)

mysql> alter table bbb add constraint bbb_fk foreign key (id) references aaa(id);
Query OK, 0 rows affected (0.84 sec)
Records: 0  Duplicates: 0  Warnings: 0

5-4-3, 删除外键约束

语法:alter table 表名 drop foreign key 约束名称

# 删除表bbb的外键约束
mysql> alter table bbb drop foreign key bbb_fk;
Query OK, 0 rows affected (0.17 sec)
Records: 0  Duplicates: 0  Warnings: 0

5-5, 检查约束(check)

check约束有用限制列的取值, 注意是否支持check约束需要看数据库的版本

5-5-1, 创建表时制定约束

语法:

create table 表名(

字段1 字段1数据类型 not null,

...

字段n 字段n数据类型 not null,

constraint 约束名称 check (条件表达式));

mysql> create table bbb(
    -> id bigint not null,
    -> name varchar(20) not null,
    -> job varchar(50) not null,
    -> address varchar(50) not null,
    -> constraint bbb_ck check (id > 1 and address = 'zh'));
Query OK, 0 rows affected (0.41 sec)

5-5-2, 修改check约束

语法:alter table 表名 add constraint 约束名称 check (条件表达式);

5-5-2, 删除check约束

语法:alter table 表名 drop check 约束名称 

5-6, 默认约束(default)

用于向指定列插入默认值

5-6-1, 创建表示制定约束

语法:

create table 表名(

字段1 字段1数据类型 not null,

...

字段x 字段x数据类型 default 默认值);

# 创建表bbb,并指定address列的默认值为zh
mysql> create table bbb(
    -> id bigint not null,
    -> name varchar(50) not null,
    -> job varchar(50) not null,
    -> address varchar(10) default 'zh');
Query OK, 0 rows affected (0.26 sec)

mysql> desc bbb;
+---------+-------------+------+-----+---------+-------+
| Field   | Type        | Null | Key | Default | Extra |
+---------+-------------+------+-----+---------+-------+
| id      | bigint(20)  | NO   |     | NULL    |       |
| name    | varchar(50) | NO   |     | NULL    |       |
| job     | varchar(50) | NO   |     | NULL    |       |
| address | varchar(10) | YES  |     | zh      |       |
+---------+-------------+------+-----+---------+-------+
4 rows in set (0.00 sec)

5-6-2, 修改默认约束

语法:alter table 表名 alter 字段x set default 默认值;

mysql> alter table bbb alter name set default '张三';
Query OK, 0 rows affected (0.09 sec)
Records: 0  Duplicates: 0  Warnings: 0

mysql> desc bbb;
+---------+-------------+------+-----+---------+-------+
| Field   | Type        | Null | Key | Default | Extra |
+---------+-------------+------+-----+---------+-------+
| id      | bigint(20)  | NO   |     | NULL    |       |
| name    | varchar(50) | NO   |     | 张三    |       |
| job     | varchar(50) | NO   |     | NULL    |       |
| address | varchar(10) | YES  |     | zh      |       |
+---------+-------------+------+-----+---------+-------+
4 rows in set (0.00 sec)

5-6-3, 删除默认约束

语法:alter table 表名 alter 字段x drop default;

# 删除name列的默认值
mysql> alter table bbb alter name drop default;
Query OK, 0 rows affected (0.16 sec)
Records: 0  Duplicates: 0  Warnings: 0

mysql> desc bbb;
+---------+-------------+------+-----+---------+-------+
| Field   | Type        | Null | Key | Default | Extra |
+---------+-------------+------+-----+---------+-------+
| id      | bigint(20)  | NO   |     | NULL    |       |
| name    | varchar(50) | NO   |     | NULL    |       |
