Shorthand for group by all columns?

I have a table with 15 columns with customer info and I want to join the sum of their purchases onto the table. I am currently attempting the following join:

SELECT  A.*, SUM(B.SALES_AMT) AS SALES
FROM CUST_INFO A
LEFT JOIN SALES_TABLE B
ON A.Cust_ID = B.Cust_ID
GROUP BY fooa, foob, fooc, etc

Is there a way to group by where I can simply say GROUP BY A.* instead of having to write out all 15 or so columns?

>Solution :

You could move the sum into an apply:

select  A.*, Isnull(B.SALES, 0) SALES
from CUST_INFO A
outer apply (
  select Sum(B.SALES_AMT) SALES
  from SALES_TABLE B
  where B.Cust_ID = A.Cust_ID
)B;
