This database contains a table called patients. Your task is to write an SQL query to extract specific information from the patients table. You need to retrieve the first_name, last_name, and allergies of patients who have allergies to either 'Penicillin' or 'Morphine'.

Ordering Criteria

Your query should return results ordered in ascending order, first by allergies, then by first_name, and finally by last_name.

Concepts to Know

  • SELECT: Used to select data from a database.
  • WHERE: Used to filter records based on specific conditions.
  • IN: The IN operator allows you to specify multiple values in a WHERE clause.
  • ORDER BY: Sorts the result-set in ascending or descending order based on one or more columns.
