페이퍼의 아래 예제만 봐도 확실히 google sql이 읽기 편하긴 하네요.

standard sql

SELECT c_count, COUNT(*) AS custdist  
FROM  
    ( SELECT c_custkey, COUNT(o_orderkey) c_count  
      FROM customer  
      LEFT OUTER JOIN orders ON c_custkey = o_custkey  
           AND o_comment NOT LIKE '%unusual%packages%'  
      GROUP BY c_custkey  
    ) AS c_orders  
GROUP BY c_count  
ORDER BY custdist DESC, c_count DESC;  

google sql

   GROUP BY c_custkey
