Question

我一直收到一个错误，告诉我插入了太多的值，但显然并非如此。有谁能够帮我。这是我的代码。目前，错误消息是INSERT INTO a2_account VALUES * 第1行的错误： ORA-00913：值太多

问题发生在创建表INSERTS后的a2_customer中，看起来您复制并粘贴了一些INSERTS而未更改表名

CREATE TABLE a2_customer (
ird_num         CHAR(8)  PRIMARY KEY, 
name            VARCHAR(200)  NOT NULL,
address         VARCHAR(200)  NOT NULL,
phone           VARCHAR(20)
);
INSERT INTO a2_customer VALUES
( '25362672', 'Stan Yel', '5 Wanna way', '02010201');
INSERT INTO a2_account VALUES
( '83783783', 'Cam Birch', '34 Trada st', '02302020202');
INSERT INTO a2_account VALUES
( '23723367', 'Jeff King', '5 Queens st', '38982383');
INSERT INTO a2_account VALUES
( '54637822', 'John Smith', '24 Queen st', '38922383');

应该是

CREATE TABLE a2_customer (
ird_num         CHAR(8)  PRIMARY KEY, 
name            VARCHAR(200)  NOT NULL,
address         VARCHAR(200)  NOT NULL,
phone           VARCHAR(20)
);
INSERT INTO a2_customer VALUES
( '25362672', 'Stan Yel', '5 Wanna way', '02010201');
INSERT INTO a2_customer VALUES
( '83783783', 'Cam Birch', '34 Trada st', '02302020202');
INSERT INTO a2_customer VALUES
( '23723367', 'Jeff King', '5 Queens st', '38982383');
INSERT INTO a2_customer VALUES
( '54637822', 'John Smith', '24 Queen st', '38922383');

Answer 2

嗯..

这3行有4个值，下划线表只有3列：

INSERT INTO a2_account VALUES
( '83783783', 'Cam Birch', '34 Trada st', '02302020202');
INSERT INTO a2_account VALUES
( '23723367', 'Jeff King', '5 Queens st', '38982383');
INSERT INTO a2_account VALUES
( '54637822', 'John Smith', '24 Queen st', '38922383');

调整此项，一切都会好的。

这是你的问题：

CREATE TABLE a2_customer (
    ird_num         CHAR(8)  PRIMARY KEY, 
    name            VARCHAR(200)  NOT NULL,
    address         VARCHAR(200)  NOT NULL,
    phone           VARCHAR(20)
    );
    INSERT INTO a2_customer VALUES
    ( '25362672', 'Stan Yel', '5 Wanna way', '02010201');
    INSERT INTO a2_account VALUES
    ( '83783783', 'Cam Birch', '34 Trada st', '02302020202');
    INSERT INTO a2_account VALUES
    ( '23723367', 'Jeff King', '5 Queens st', '38982383');
    INSERT INTO a2_account VALUES
    ( '54637822', 'John Smith', '24 Queen st', '38922383');

您创建了客户，然后尝试插入帐户。
