MySQL error #1054 - Unknown column in 'Field List'

Question

Whenever I try to input data into my tblorder I get the error message #1054 - Unknown column 'FK_Customer_ID' in 'field list'. I have tried breaking my code down and in doing this I found that the error is repeated for FK_Customer_ID and OrderQuantity whereas FK_DVD_ID it will take single data entries. I have tried dropping the table and recreating it, I have dropped the database and recreated it but nothing works. As far as I can tell my code is correct along with my spelling so I'm really stuck.

My tblorder is-

CREATE TABLE tblorder
(   
 Order_ID INT AUTO_INCREMENT NOT NULL,  
 FK_Customer_ID INT NOT NULL,   
 FK_DVD_ID INT NOT NULL,    
 OrderDate DATETIME NOT NULL DEFAULT NOW(),
 OrderQantity INT NOT NULL, 
 PRIMARY KEY (Order_ID),    
 FOREIGN KEY (FK_Customer_ID) REFERENCES tblcustomer (Customer_ID), 
 FOREIGN KEY (FK_DVD_ID) REFERENCES tbldvd (PK_ID)
);

The data I am trying to put in is-

INSERT INTO tblorder
 (FK_Customer_ID, FK_DVD_ID, OrderQuantity)
VALUES 
 (1, 3, 2),
 (1, 5, 1),
 (1, 10, 4), 
 (1, 15, 3),
 (2, 5, 4),
 (2, 17, 3),
 (3, 15, 1),
 (3, 16, 1),
 (3, 17, 1);

FK_Customer_ID is addressing -

CREATE TABLE tblcustomer
(
 Customer_ID INT AUTO_INCREMENT NOT NULL,
 FirstName VARCHAR(50) NOT NULL,
 LastName VARCHAR(50) NOT NULL,
 Age INT NOT NULL,
 PRIMARY KEY (Customer_ID)
);

FK_DVD_ID is addressing -

CREATE TABLE tblDVD
(
 PK_ID INT AUTO_INCREMENT NOT NULL,
 Title VARCHAR(100) NOT NULL,
 DIrector VARCHAR(100) NOT NULL,
 Genre VARCHAR(40) NOT NULL,
 dvd_Year YEAR NOT NULL,
 Price FLOAT(2) NOT NULL,
 Quantity INT NOT NULL,
 PRIMARY KEY (PK_ID)
);

Any help in fixing the will be greatly appreciated as it will help me with my A2 computing lesson!

Answer 1

You have an error in your OrderQuantity column. It is named "OrderQuantity" in the INSERT statement and "OrderQantity" in the table definition.

Also, I don't think you can use NOW() as default value in OrderDate. Try to use the following:

 OrderDate TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP

Answer 2

I had this error aswell.

I am working in mysql workbench. When giving the values they have to be inside "". That solved it for me.
