MySQL 如何将自己的值插入MySQL中的auto_increment列

您可以通过INSERT语句实现此目的，即可以像正常插入一样简单地插入它。语法如下 −

INSERT INTO yourTableName (yourIdColumnName,yourColumnName) values(value1,'value2');
让我们先创建一张表：
mysql> create table InsertValueInAutoIncrement
   -> (
   -> UserId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   -> UserName varchar(20)
   -> );
Query OK, 0 rows affected (0.59 sec)

现在，您可以使用插入命令在表中插入一些记录。在此，我们还为自动增量字段UserId插入了自己的值。查询语句如下 −

mysql> insert into InsertValueInAutoIncrement(UserName) values('John');
Query OK, 1 row affected (0.19 sec)
mysql> insert into InsertValueInAutoIncrement(UserName) values('Carol');
Query OK, 1 row affected (0.17 sec)
mysql> insert into InsertValueInAutoIncrement(UserName) values('Sam');
Query OK, 1 row affected (0.11 sec)
mysql> insert into InsertValueInAutoIncrement(UserName) values('Bob');
Query OK, 1 row affected (0.18 sec)
mysql> insert into InsertValueInAutoIncrement(UserId,UserName) values(100,'Maxwell');
Query OK, 1 row affected (0.18 sec)
mysql> insert into InsertValueInAutoIncrement(UserName) values('James');
Query OK, 1 row affected (0.20 sec)
mysql> insert into InsertValueInAutoIncrement(UserId,UserName) values(1000,'Larry');
Query OK, 1 row affected (0.12 sec)

使用select语句显示表中的所有记录。查询语句如下 −

mysql> select *from InsertValueInAutoIncrement;

以下是该表 −

+--------+----------+
| UserId | UserName |
+--------+----------+
|      1 | John     |
|      2 | Carol    |
|      3 | Sam      |
|      4 | Bob      |
|    100 | Maxwell  |
|    101 | James    |
|   1000 | Larry    |
+--------+----------+
7 rows in set (0.00 sec)
