SQL – Assignment 1

Overview: Total 100 points.There are three tasks in this assignment: A) create tables, B) insert data, and C) query single table. For each task, you need to write SQL command and run it in Oracle SQLPlus Worksheet. What you need to submit are:

1. the SQL command;2. the results copy and paste from Oracle SQLPlus Worksheet result window.

A. Create Tables

5 points for each table. The logical schema is shown as below:

Hint: you have two ways to define foreign key, one is to define foreign key within the CREATE TABLE statement as in SQL Lab 1, for example:

CREATE TABLE products (product_id numeric(10) not null, supplier_id numeric(10),

1

CONSTRAINT fk_supplier FOREIGN KEY (supplier_id) REFERENCES supplier(supplier_id) ON DELETE SET NULL);

Another way is to create table without defining foreign key and add foreign key later using the ALTER TABLE statement (sometimes you might have to do like this), for example:

ALTER TABLE ProductsADD CONSTRAINT fk_supplier FOREIGN KEY (supplier_id) REFERENCES supplier(supplier_id) ON DELETE SET NULL;
