Suppose I have a tasks table which contains tasks created by several people and where each task can be assigned to any other user,
with columns like these:

status - A string value, can be Open, In Progress or Closed
created_by - int value, stores the id of the user who created the task
assigned_to - int value, stores the id of the user assigned to a task

And I want to see only open tasks created by or assigned to me, i.e. the query:

SELECT * FROM tasks WHERE status = 'Open' AND (created_by = 3 OR assigned_to = 3)

How can I do this using CodeIgniter ActiveRecord?
