Oracle 创建视图内部联接错误

我正在创建视图并使用内部联接，收到以下错误：

ORA-00904: "B"."CUSTOMERNO": invalid identifier

这是我用来创建视图和内部联接的代码

CREATE VIEW RentalInfoOct
(branch_no, branch_name, customer_no)
AS
SELECT b.branchNo, b.branchName, b.customerNo, c.customerNo
FROM branch b
INNER JOIN 
customer c
ON b.customerNo = c.customerNo

以下是创建表格命令

CREATE TABLE Branch
(
branchNo    SMALLINT    NOT NULL,
branchName  VARCHAR(20) NOT NULL,
branchAddress   VARCHAR(40) NOT NULL,
PRIMARY KEY (BranchNo)
);  

CREATE TABLE Customer
(
customerNo      SMALLINT    NOT NULL,
customerName        VARCHAR(15) NOT NULL,
customerAddress     VARCHAR(40) NOT NULL,
customerTel         VARCHAR(10),
PRIMARY KEY (CustomerNo)
);

---

为视图指定3列，但在select中选择4列，分支表上没有customerNo列。

CREATE VIEW RentalInfoOct
(branch_no, branch_name, customer_no)
AS
SELECT b.branchNo, b.branchName, b.customerNo, c.customerNo
