# Queries

## Setup

Create the database in the data explorer. If you're using a shared instance of RethinkDB, name space your database name with your GitHub handle. If you're running these queries locally, you don't need to name space your database name.
```
r.dbCreate('GITHUB_HANDLE_rethinkdb_workshop')
r.db('GITHUB_HANDLE_rethinkdb_workshop').tableCreate('reddit')
```
