Persistence

Part 1: SQL

The following lab is to be completed using the H2 Console. Once you have figured out the correct queries for each step, save a copy in a file called src/main/resources/script.sql. This will be how you submit this assignment. If at any time you need to reset the database, you can restart your Spring Boot server.

Mini Movie Database

Add the following movies to the movies table using an insert statement:

Title Runtime Genre IMDB Score Rating
Howard the Duck 110 Sci-Fi 4.6 PG
Lavalantula 83 Horror 4.7 TV-14
Starship Troopers 129 Sci-Fi 7.2 PG-13
Waltz With Bashir 90 Documentary 8.0 R
Spaceballs 96 Comedy 7.1 PG
Monsters Inc. 92 Animation 8.1 G

Add a few more movies of your choosing.

Create a query to find all movies in the Sci-Fi genre.

Create a query to find all films that scored at least a 6.5 on IMDB

For parents who have young kids, but who don't want to sit through long children's movies, create a query to find all of the movies rated G or PG that are less than 100 minutes long.

Create a query to show the average runtimes of movies rated below a 7.5, grouped by their respective genres.

There's been a data entry mistake; Starship Troopers is actually rated R, not PG-13. Create a query that finds the movie by its title and changes its rating to R.

Show the ID number and rating of all of the Horror and Documentary movies in the database. Do this in only one query.

This time let's find the average, maximum, and minimum IMDB score for movies of each rating.

That last query isn't very informative for ratings that only have 1 entry. use a HAVING COUNT(*) > 1 clause to only show ratings with multiple movies showing.

Let's make our movie list more child-friendly. Delete all entries that have a rating of R. Remember to record your query in script.sql.
