    INNER JOIN
     (
      SELECT 
            MAX(count)  as MaxCount,
            docName
      FROM 
            (SELECT 
                  COUNT(docname) 
             FROM 
                  doctor 
             GROUP BY 
                  docname
            )
      ) m ON m.DocName = author.DocName
