2023 1 Project 2 Details Create Oracle database tables using SQL Data Definition Language DDL for each table listed in | Assignment Collections

1. Project 2 Details: Create Oracle database tables using SQL Data Definition Language (DDL) for each table listed in Project 1. Make sure that entity and referential integrity are enforced by declaring a primary key for each table (these may be composite keys) and declaring all appropriate foreign keys. Your CREATE TABLE statements must show integrity constraints, as appropriate, for NOT NULL, UNIQUE, PRIMARY KEY, FOREIGN KEY, REFERENCES, and CHECK constraints. You should test your script to make sure it runs without error. Capture the script output showing that all SQL in your SQL script file worked properly.

#2. Provide two examples of SQL DML (i.e., “INSERT”) commands that fail different table integrity constraints you set up in one of your table. Explain why the statements fail. You should include comments in the SQL script describing why the insert statements failed. Capture the script output showing that all SQL in your SQL script file worked properly.

#3.  Populate each of your tables with at least five valid rows of data each and show the SQL you used. Populate other tables in your database, as necessary, to satisfy referential integrity. You should test your script to make sure it runs without error. Capture the script output showing that all SQL in your SQL script file worked properly.

#4. Write SQL to perform the following queries and updates. You should test your script to make sure it runs without error:

Retrieve all of your customers’ names, account numbers, and addresses (street and zip code only), sorted by account number.

Retrieve all of the videos rented in the last 30 days and sort in chronological rental date order.

Produce a list of your distributors and all their information sorted in order by company name.

Update a customer name to change their maiden names to married names. You can choose which row to update. Make sure that you use the primary key column in your WHERE clause to affect only a specific row.

Delete customers from the database. You can choose which row to delete. Make sure that you use the primary key column in your WHERE clause to affect only a specific row.
