SQL Query and DB Expert Needed

I am currently getting a 500 error on my website. I traced it back to an SQL query (SELECT XYZ FROM zip_code INNER JOIN city ON zip_code.city_id = city.city_id INNER JOIN region ON city.region_id = region.region_id INNER JOIN country ON region.country_id = country.country_id). The INNER JOIN country ON region.country_id = country.country_id part of it seems to be the issue. I need a quick solution for this problem. I am running a MySQL database on the backend. Goal here is to get rid of the 500 error so the program will run as desired. Please note, I do not consider running multiple queries a solution. Thanks!
