Question

我正在尝试使用一个简单的数据库，这样我就可以使用我的PHP，我正在从一本书中复制它，这是代码：

USE testeDB;

CREATE TABLE test(
id INT not null AUTO_INCREMENT,
nome VARCHAR (25),
telefone VARCHAR (12);
PRIMARY KEY (id),
);

INSERT INTO teste VALUES ('', 'Joaquim', '1111');
INSERT INTO teste VALUES ('', 'Carlos', '2233');
INSERT INTO teste VALUES ('', 'Antonio', '3333');
INSERT INTO teste VALUES ('', 'Roque Santeiro', '6969');

我使用phpmyadmin创建数据库，但是当我运行该代码来创建表时，我收到以下错误：

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 4

它必须是简单的东西，但我无法确定问题是什么。有人可以帮帮我吗？

Answer 1

创建表

时出现

语法错误

CREATE TABLE test(
id INT not null AUTO_INCREMENT,
nome VARCHAR (25),
telefone VARCHAR (12),  -- <=== here
PRIMARY KEY (id),
);

因为id为auto incremented，你可以这样做，

-- pass NULL value to column ID since the server automatically
-- assigns the value of the ID for it. also notice that you have specify 
-- column ID as the primary so it won't have duplicated value for ID
-- NULL is NOT THE SAME as empty string
-- NULL is NOTHING (or unknown) and 
-- Empty string is a zero-length string
INSERT INTO test VALUES (null, 'Joaquim', '1111');    
INSERT INTO test VALUES (null, 'Carlos', '2233');
INSERT INTO test VALUES (null, 'Antonio', '3333');
INSERT INTO test VALUES (null, 'Roque Santeiro', '6969');

OR

-- explicitly supply the column you want to insert value
INSERT INTO test (nome, telephone) VALUES ('Joaquim', '1111');
INSERT INTO test (nome, telephone) VALUES ('Carlos', '2233');
INSERT INTO test (nome, telephone) VALUES ('Antonio', '3333');
....

Answer 2

telefone VARCHAR (12);

应该是

telefone VARCHAR (12),

祝你好运！

Answer 3

另一个问题是：

CREATE TABLE test(
id INT not null AUTO_INCREMENT,
nome VARCHAR (25),
telefone VARCHAR (12);
PRIMARY KEY (id),
);

INSERT INTO teste VALUES ('', 'Joaquim', '1111');
INSERT INTO teste VALUES ('', 'Carlos', '2233');
INSERT INTO teste VALUES ('', 'Antonio', '3333');
INSERT INTO teste VALUES ('', 'Roque Santeiro', '6969')

teste不存在，您需要使用test（来自CREATE TABLE语法），插入它看起来像：

   INSERT INTO test VALUES ('Joaquim', '1111');
    INSERT INTO test VALUES ('Carlos', '2233');
    INSERT INTO test VALUES ('Antonio', '3333');
    INSERT INTO test VALUES ('Roque Santeiro', '6969')


-- Not need to put the '' either since the value is auto incrementing (more here:http://dev.mysql.com/doc/refman/5.0/en/example-auto-increment.html)
