羅德興老師的教學歷程檔案 - 中華科技大學數位化學習歷程

-- 請建立一個資料庫 test_xxx，完成後請
-- (1) 在答案紙上寫下三個表格的欄位 (並標出關鍵值)，與表格之間的關係

-- (2) 展示給老師評分

-- 有三個表格 (tables) 如下，請寫出SQL解決下列問題 1-10：

supplier (s_id, s_name, address) 廠商 (廠商編號，廠商名稱，地址)	product (p_id, name, cost) 商品 (商品編號，商品名稱，單價)	ordering (s, p, qty) 訂購單 (廠商編號，商品編號，訂購數量)

DROP DATABASE IF EXISTS test_xxx; -- 刪除資料庫

CREATE DATABASE `test_xxx` CHARACTER SET utf8; -- 建立資料庫採 utf8 編碼

-- 新增 table

USE test_xxx;

-- 利用 AUTO_INCREMENT 自動累加，給該筆記錄一個獨一無二的編號，

-- 像是給它一個ID，或是一個Index等等，自動從一開始設定的值 (預設是1) 一直累加上去。

CREATE TABLE supplier_xxx (

s_id int NOT NULL AUTO_INCREMENT,

s_name char(100),

address char(120) NOT NULL,

PRIMARY KEY (s_id)

) CHARACTER SET=utf8, ENGINE=INNODB;

CREATE TABLE product_xxx (

p_id char(10) NOT NULL,

name char(50),

cost int NOT NULL,

PRIMARY KEY (p_id)

) CHARACTER SET=utf8, ENGINE=INNODB;

CREATE TABLE ordering_xxx (

s int NOT NULL,

p char(10) NOT NULL,

qty int,

PRIMARY KEY (s,p),

CONSTRAINT sp_fk2

FOREIGN KEY (s) REFERENCES supplier_xxx(s_id)

ON DELETE NO ACTION

ON UPDATE CASCADE,

CONSTRAINT sp_fk3

FOREIGN KEY (p) REFERENCES product_xxx(p_id)

ON DELETE NO ACTION

ON UPDATE CASCADE

) CHARACTER SET=utf8, ENGINE=INNODB;

-- type=innodb 相當於 engine=innodb

-- 新增 table 內的資料
