当我执行我的代码时，我总是收到“无效列名”？

Answer 1

第一个错误是由于这个

Create TABLE tblInvoice 
(
InvoiceID INT IDENTITY(1,1) PRIMARY KEY, 
Date DATE NOT NULL, 
Subtotal MONEY , 
SalesTax MONEY , 
Total MONEY , 
ShipDate DATE, 
ShipHand MONEY NULL 
) 
GO 

这

ALTER TABLE tblInvoice 
ADD CONSTRAINT Customer_ID_FK FOREIGN KEY (CustomerID) 
REFERENCES tblCustomer(CustomerID) 
GO 

有一个在tblInvoice没有CustomerID列。 如果你想增加一列，这样做，然后添加外键：

ALTER TABLE tblInvoice 
ADD CustomerID INT NOT NULL 
GO 

同样的，你没有SalesID在发票表和您尝试将数据插入到它。

INSERT INTO tblInvoice (DATE, CustomerID, SalesID, Total, Salestax, ShipDate, ShipHand) 
VALUES ('2010-8-5 8:30 am', @CustomerID, @SalesID, '174.44', '17.44', '2010-8-6 8:45 am', '10.99')
