如何在MySQL的auto_increment列中插入自己的值？
您可以借助INSERT语句来实现此目的，即，您可以像普通插入一样简单地将其插入。语法如下-
INSERT INTO yourTableName (yourIdColumnName,yourColumnName) values(value1,'value2'); Let us first create a table: mysql> create table InsertValueInAutoIncrement -> ( -> UserId int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> UserName varchar(20) -> );
现在，您可以使用insert命令在表中插入一些记录。在这里，我们还将为auto_increment字段UserId插入我们自己的值。查询如下-
mysql> insert into InsertValueInAutoIncrement(UserName) values('John');
mysql> insert into InsertValueInAutoIncrement(UserName) values('Carol');
mysql> insert into InsertValueInAutoIncrement(UserName) values('Sam');
mysql> insert into InsertValueInAutoIncrement(UserName) values('Bob');
mysql> insert into InsertValueInAutoIncrement(UserId,UserName) values(100,'Maxwell');
mysql> insert into InsertValueInAutoIncrement(UserName) values('James');
mysql> insert into InsertValueInAutoIncrement(UserId,UserName) values(1000,'Larry');使用select语句显示表中的所有记录。查询如下-
mysql> select *from InsertValueInAutoIncrement;
下表是-
+--------+----------+ | UserId | UserName | +--------+----------+ | 1 | John | | 2 | Carol | | 3 | Sam | | 4 | Bob | | 100 | Maxwell | | 101 | James | | 1000 | Larry | +--------+----------+ 7 rows in set (0.00 sec)
