Question

I have two tables one with observers and another with animals.

Im trying to get the name of observers who have either seen more than 5 animals OR seen a bear.

I am able to get observers with more than 4 animals but not sure how to do the OR statement.

This is my code:

SELECT o.last_name, o.first_name, a.observer_id, count (a.observer_id) as Animals_Seen
from animals as a inner join observer as o 
on a.observer_id = o.observer_id
group by a.observer_id, o.last_name, o.first_name
having count (a.observer_id) > 4;

This is what I get:

Answer 1

Set a boolean value to 1 whenever a bear is spotted… then check whether the observer’s bear count > 0:

select
    o.last_name, o.first_name, a.observer_id, count(a.observer_id) as Animals_Seen,
    sum(iif(a.animal = "bear", 1, 0)) as BearCount
from 
    animals as a inner join observer as o 
on 
    a.observer_id = o.observer_id
group by 
    a.observer_id, o.last_name, o.first_name
having
    count(a.observer_id) > 4 or sum(iif(a.animal = "bear", 1, 0)) > 0
