using count query in sql

Question

How could I write an SQL that will display authors and a total number of their publications with a sub query included in my SELECT STATEMENT but this is what I have

I believe you missed a sentence. Why do you need a subquery here? — ffflabs

Please don't insert screenshots of code or queries, insert them as text into the question and format as code (4 spaces indent) — fvu

SELECT a.auth_name,COUNT( p.pub_title ) AS count_of_publications 
  FROM Author a
LEFT JOIN
       Wrote w
    ON a.auth_id = w.auth_id
LEFT JOIN 
       Publication p
    ON w.pub_id = p.pub_id
GROUP BY a.auth_name;
