Cleanup

First, do Question 2. Then, come back and complete this part.
Write SQL statements that drop the tables you created in Question 2 if they already exist. This will
prepare the database for the CREATE TABLE commands in Question 2, so that the script will execute
without errors.
You have the permissions required to create tables in the CIS275Sandboxx database.
Hint: The syntax for dropping a table if it exists in SQL looks like this:
‘
/*
IF OBJECT_ID(‘ABC_RecipeIngredient’, ‘U’) IS NOT NULL
DROP TABLE ABC_RecipeIngredient;
*/
+ ‘
You will also need to drop the view you create for Question 5. The SQL for that looks like:
‘
/*
IF OBJECT_ID(‘ABC_all_data’, ‘V’) IS NOT NULL
DROP VIEW ABC_all_data;
*/
+ ‘
Hint 2: Foreign key constraints will cause errors unless you drop the tables in the right order.
Drop the tables with foreign keys before you drop the tables with the primary keys those tables
depend on.

Create Tables
————-
Using the ERD from the Lab 8 assignment document (see course shell), create the tables represented
in the ERD. For full credit, please pay attention to the following:
0. Examine the sample data in Question 3 first. You”ll want to make sure the data types you
pick for each column are compatible with the data we”re storing in the tables.
1. Prefix the table names with your initials (for example, name your table ABC_RecipeIngredient
ABC_RecipeIngredient instead of RecipeIngredient.
2. All primary key fields should be declared with PRIMARY KEY constraints.
3. Declare all non-composite primary keys using IDENTITY(1, 1).
4. Create the correct FOREIGN KEY constraints for all foreign keys.
5. The following values are all optional:
a. Preparation in Ingredient
b. Organization in Chef
c. FK_ChefID in Recipe
All other values are mandatory. Add the correct data integrity constraints for this.
6. Name in Recipe should be distinct. Add the correct data integrity constraint for this.
7. FK_IngredientID and FK_RecipeID form a composite primary key for the RecipeIngredient table
(as well as being foreign keys on their own).
8. If you have two tables with a primary key/foreign key relationship, you”ll need to create
the table with the primary key BEFORE you create the table with the foreign key constraint.

Adding another Recipe
———————
Write additional INSERT INTO statements to add the following recipe to the database:
Ree”s Simple Sesame Noodles
By Ree Drummond, Food Network
Quantity Units Ingredient Preparation
——– ———- ——————– ——————–
4 cloves garlic minced
4 whole green onion thinly sliced
1/4 cup soy sauce NULL
3 tbsp sesame oil NULL
2 tbsp rice vinegar NULL
2 tbsp sugar NULL
12 oz thin noodles NULL
1/4 cup canola oil NULL
1/2 tsp hot chili oil NULL
Bring a large pot of water to a boil. Cook the noodles according to the package instructions.
Meanwhile, whisk together the soy sauce, canola oil, sesame oil, sugar, vinegar, chili oil and
garlic in a bowl. Taste and adjust the ingredients as needed.
Drain the noodles. Pour the sauce over the warm noodles and toss to coat. Sprinkle with the
green onions and toss. Serve in a bowl with chopsticks. Yummy!
Note: Reuse existing ingredients instead of creating duplicates. E.g., minced garlic is already
in the database as IngredientID 4, so you don”t need to create a new row for that ingredient in
the Ingredient table.
Hint: Look at how the recipe data is structured in Question 3 and in the ERD.

create the view, go back to Question 1 and add a SQL command to drop the view if it exists. Then,
add a statement that SELECTs * from your view (you will need to add a GO before the SELECT statement).

After the UPDATEs in the previous question, there are now some ingredients that aren”t being
used in any recipes. Write a DELETE statement that deletes all unused ingredients. Use a SELECT
statement as a subquery in the WHERE clause of the DELETE statement that finds the correct
ingredients to delete (i.e., don”t hard-code the ingredient IDs for the ingredients to delete).
Then, SELECT * from all_data and from Ingredient to verify that your delete worked correctly.
