単純なSQLクエリを実行できません

Question

なんらかの理由で、最初の2つのテーブルは、SQL FIDDLEをSQL Fiddleに単独で配置すると、SQL FIDDLEでクエリされます。私はテーブルにすべてのテーブルを置くと、クエリと私はメッセージが表示されます：テーブルdb_9_9eecb7d.customerは存在しません。ヒントや助けをいただければ幸いです。ここで

は、私が書いたコードです：

CREATE TABLE Customer 
( CustomerID INT(255) NOT NULL AUTO_INCREMENT, 
    FirstName VARCHAR(255) NOT NULL, 
    LastName VARCHAR(255) NOT NULL, 
    StreetAddress VARCHAR(255) NOT NULL,

    HomePhone CHAR(10) NOT NULL, 
    MobilePhone CHAR(10) NOT NULL, 
    OtherPhone CHAR(10) NOT NULL, 
    PRIMARY KEY(CustomerID) 
); 

INSERT INTO Customer 
    (FirstName, LastName, StreetAddress, Apartment, City, State, 
     ZipCode, HomePhone, MobilePhone, OtherPhone)

    'WA', 98408, 4173231111, 1234567788, 5555551212); 

SELECT CustomerID, (CONCAT(firstname, ' ', Lastname)) as FullName, StreetAddress, Apartment, City, State, ZipCode, Homephone, mobilephone, otherphone FROM customer; 

CREATE TABLE Donut 
( 
    DonutID INT(255) NOT NULL AUTO_INCREMENT, 
    Name VARCHAR(255) NOT NULL, 
    Description VARCHAR(255) NOT NULL, 
    UnitPrice DECIMAL(3, 2) NOT NULL, 
    PRIMARY KEY(DonutID

CREATE INDEX DonutName ON Donut(Name); 

CREATE TABLE DonutOrder 
    (DonutOrderID INT(255) NOT NULL, 
     DonutID INT(255) NOT NULL, 
     Quantity INT(255), 
     PRIMARY KEY(DonutOrderID, donutID), 
     INDEX Donut(donutID)); 

INSERT INTO DonutOrder(DonutID, Quantity) 
VALUES((SELECT DonutID FROM Donut WHERE DonutID = 1), 1), 
     ((SELECT DonutID FROM Donut WHERE DonutID = 2), 5), 
     ((SELECT DonutID FROM Donut WHERE DonutID = 3), 12), 
     ((SELECT DonutID FROM Donut WHERE DonutID = 4), 3), 
     ((SELECT DonutID FROM Donut WHERE DonutID = 5), 4), 
     ((SELECT DonutID FROM Donut WHERE DonutID = 6), 5); 

CREATE TABLE SalesInvoice 
(
    CustomerID INT(255) NOT NULL, 
    DonutOrderID INT(255) NOT NULL AUTO_INCREMENT, 
    `Date` 
    date NOT NULL, 
    Spec_Hnd_Inst VARCHAR(255), 
    PRIMARY KEY(DonutOrderID), 
    INDEX Customer(CustomerID), 
    FOREIGN KEY(CustomerID) REFERENCES Customer(CustomerID), 
    INDEX DonutOrder(donutOrderID)); 

INSERT INTO SalesInvoice(CustomerID, DonutOrderID, `Date`, Spec_Hnd_Inst) VALUES(1, 1, '20160319', 'Extra Sugar');

Thisが動作しているようです。

INSERT INTO DonutOrder (DonutID, Quantity) 
VALUES ((SELECT DonutID FROM Donut WHERE DonutID = 1), 1),

INDEX DonutOrder (donutOrderID)); 

INSERT INTO SalesInvoice (CustomerID, DonutOrderID, Date,Spec_Hnd_Inst) VALUES (1, 1, '20160319', 'Extra Sugar'); 

を構築し、挿入された値

select * from SalesInvoice;

テーブル 'db_9_9eecb7d.customer' をチェックするために右に以下を追加するには、左側に次の行を追加します

このエラーは発生しませんが、テーブルの顧客が見つかりませんでした。データベースは構成によっては大文字と小文字が区別されるので、代わりにCustomerを使用してください。
