It's only a game!

Research harder

Who's the custodian?

You have three tables in a PostgreSQL database.
  • users
  • roles
  • user_roles
Produce a query that generates two columns.

  1. "Custodian" : Contains boolean "true" when the person's role is "Janitor", "false" in all other instances.
  2. "Person" : Contains the user's name, sorted ascending.

The columns in your ResultSet MUST be named exactly, in this order:
  • Custodian
  • Person


Good Luck!
Enter your query below and click submit.
