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.

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