看sql必知必會，苦於沒有相關的表進行練習，網上查詢，解決了問題，將內容整理如下：

cmd登陸mysql（我使用的是xampp自帶的mysql，無法直接在cmd開啟，因需要提前將xampp底下mysql的bin目錄的絕對路徑加入到path環境變數中，然後進入cmd，輸入mysql -u root -p連線mysql伺服器，creat orderdb;建立資料庫，use orderdb;進入orderdb資料庫後輸入如下兩個文件的sql語句）

一、建立五張表的sql語句

-------------------------------------------- -- Sams Teach Yourself SQL in 10 Minutes -- http://www.forta.com/books/0672325675/ -- Example table creation scripts for MySQL. --------------------------------------------

------------------------- -- Create Customers table ------------------------- CREATE TABLE Customers (   cust_id      char(10)  NOT NULL ,   cust_name    char(50)  NOT NULL ,   cust_address char(50)  NULL ,   cust_city    char(50)  NULL ,   cust_state   char(5)   NULL ,   cust_zip     char(10)  NULL ,   cust_country char(50)  NULL ,   cust_contact char(50)  NULL ,   cust_email   char(255) NULL  );

-------------------------- -- Create OrderItems table -------------------------- CREATE TABLE OrderItems (   order_num  int          NOT NULL ,   order_item int          NOT NULL ,   prod_id    char(10)     NOT NULL ,   quantity   int          NOT NULL ,   item_price decimal(8,2) NOT NULL  );

---------------------- -- Create Orders table ---------------------- CREATE TABLE Orders (   order_num  int      NOT NULL ,   order_date datetime NOT NULL ,   cust_id    char(10) NOT NULL  );

------------------------ -- Create Products table ------------------------ CREATE TABLE Products (   prod_id    char(10)      NOT NULL ,   vend_id    char(10)      NOT NULL ,   prod_name  char(255)     NOT NULL ,   prod_price decimal(8,2)  NOT NULL ,   prod_desc  text          NULL  );

----------------------- -- Create Vendors table ----------------------- CREATE TABLE Vendors (   vend_id      char(10) NOT NULL ,   vend_name    char(50) NOT NULL ,   vend_address char(50) NULL ,   vend_city    char(50) NULL ,   vend_state   char(5)  NULL ,   vend_zip     char(10) NULL ,   vend_country char(50) NULL  );

---------------------- -- Define primary keys ---------------------- ALTER TABLE Customers ADD PRIMARY KEY (cust_id); ALTER TABLE OrderItems ADD PRIMARY KEY (order_num, order_item); ALTER TABLE Orders ADD PRIMARY KEY (order_num); ALTER TABLE Products ADD PRIMARY KEY (prod_id); ALTER TABLE Vendors ADD PRIMARY KEY (vend_id);

---------------------- -- Define foreign keys ---------------------- ALTER TABLE OrderItems ADD CONSTRAINT FK_OrderItems_Orders FOREIGN KEY (order_num) REFERENCES Orders (order_num); ALTER TABLE OrderItems ADD CONSTRAINT FK_OrderItems_Products FOREIGN KEY (prod_id) REFERENCES Products (prod_id); ALTER TABLE Orders ADD CONSTRAINT FK_Orders_Customers FOREIGN KEY (cust_id) REFERENCES Customers (cust_id); ALTER TABLE Products ADD CONSTRAINT FK_Products_Vendors FOREIGN KEY (vend_id) REFERENCES Vendors (vend_id);
