## Setup
|
|
|
|
1. Create a new database called `DogGroomer`, connect to it, and run the following code (given to you in the `schema.sql` file inside of the `groomer_seed_data` directory):
|
|
- Note: You can run this .sql file using `psql <db_name> -f <path_to_file>`
|
|
|
|
```sql
|
|
drop table if exists dogs;
|
|
drop table if exists owners;
|
|
drop table if exists groomers;
|
|
|
|
create table dogs(
|
|
id serial primary key,
|
|
name varchar(255) not null,
|
|
breed varchar(255) not null,
|
|
owner integer,
|
|
groomer integer
|
|
);
|
|
|
|
create table owners(
|
|
id serial primary key,
|
|
name varchar(255) not null,
|
|
groomer integer,
|
|
dogs integer[]
|
|
);
|
|
|
|
create table groomers(
|
|
id serial primary key,
|
|
name varchar(255) not null,
|
|
rate integer not null,
|
|
owners integer[],
|
|
dogs integer[]
|
|
);
|
|
```
|
|
1. In terminal, connect to your `DogGroomer` database
|
|
1. Once inside the psql database (you'll know you're in the right one if your terminal says `DogGroomer=#`), copy and paste the seed data from `dogs.sql`, `groomers.sql` and `owners.sql` into your terminal.
|
|
1. Query for `*` in each of the three tables to make sure the data was inputted correctly.
|
|
|
|
## Activity
|
|
|
|
- In the `answers.sql` file you will find a series of challenges. Below them, type the appropriate SQL command to access the data requested.
|
|
- You must complete at least 8 of the provided challenges for a completion on this assignment.

#### Heads Up!
|
|
|
|
Some of the Data in the tables is in the form of an array! Check out the [PostgreSQL Docs](https://www.postgresql.org/docs/9.1/arrays.html) about arrays before you start!
|
|
|
|
|
|
#### Hungry For More?
|
|
|
|
- Use joins to solve the appropriate questions.
