+## 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.

+### Campy 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.
+
+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`.
