下一節(jié)我們將會使用兩張新表——happyorder和happydetail。創(chuàng)建兩張表的代碼如下——

創(chuàng)建happyorder表：

CREATE TABLE happyorder (menu_num int NOT NULL AUTO_INCREMENT,order_time datetime NOT NULL ,tab_num int NOT NULL ,per_num int NOT NULL,new_client char(10) NULL,PRIMARY KEY (menu_num) ) ENGINE=InnoDB;

創(chuàng)建happydetail表：

CREATE TABLE happydetail (menu_num int NOT NULL ,menu_item int NOT NULL ,dishes char(10) NOT NULL ,quantity int NOT NULL ,price decimal(8,2) NOT NULL ,PRIMARY KEY (menu_num, menu_item) ) ENGINE=InnoDB;

往happyorder表中插入數(shù)據(jù)：

INSERT INTO happyorder(menu_num, order_time, tab_num, per_num, new_client) VALUES(1001, '2005-09-01 17:30:01','1', '4', null); INSERT INTO happyorder(menu_num, order_time, tab_num, per_num, new_client) VALUES(1002, '2005-09-01 18:31:41','2', '2', 'Yes'); INSERT INTO happyorder(menu_num, order_time, tab_num, per_num, new_client) VALUES(1003, '2005-09-01 18:35:51','3', '3', null); INSERT INTO happyorder(menu_num, order_time, tab_num, per_num, new_client) VALUES(1004, '2005-09-01 18:40:51','5', '8', 'Yes'); INSERT INTO happyorder(menu_num, order_time, tab_num, per_num, new_client) VALUES(1005, '2005-09-01 18:48:51','7', '1', null); INSERT INTO happyorder(menu_num, order_time, tab_num, per_num, new_client) VALUES(1006, '2005-09-01 19:35:51','1', '2', 'Yes'); INSERT INTO happyorder(menu_num, order_time, tab_num, per_num, new_client) VALUES(1007, '2005-09-01 19:40:51','2', '3', null); INSERT INTO happyorder(menu_num, order_time, tab_num, per_num, new_client) VALUES(1008, '2005-09-01 20:10:51','4', '3', 'Yes'); INSERT INTO happyorder(menu_num, order_time, tab_num, per_num, new_client) VALUES(1009, '2005-09-01 20:50:51','1', '1', null); INSERT INTO happyorder(menu_num, order_time, tab_num, per_num, new_client) VALUES(1010, '2005-09-01 20:30:51','2', '6', 'Yes'); INSERT INTO happyorder(menu_num, order_time, tab_num, per_num, new_client) VALUES(1011, '2005-09-01 20:30:51','3', '4', 'Yes'); INSERT INTO happyorder(menu_num, order_time, tab_num, per_num, new_client) VALUES(1012, '2005-09-01 21:00:51','6', '5', 'Yes');
