     Oracle:

 
Use the CUBE function
 
Your exercise is to extend the following SQL statements to provide aggregations.  This exercise is not graded, but we highly recommend that you take the time to fully understand the powerful functionality of CUBE.  We start with a report that shows each publisher, the types of books they publish, the number of titles for each book type, and the sum of all sales for each publisher-type pair:
 
PUB_NAME         BOOK_TYPE       NBR_TITLES SUM_SOLD                           
---------------- --------------- ---------- --------                           
big city         fiction                  6    1,800                           
                 miscellaneous            5    1,300                           
bookhouse        computer                14   29,780                           
                 miscellaneous            7    8,400                            
                 music                   11   16,290                           
desk top         management               7    9,200                           
learning works   computer                 5    1,400                            
                 management               5    2,250                           
mammoth house    computer                 7    4,500                           
                 fiction                  6    2,750                            
mountain         fiction                  5    9,880                           
nitpick and sons computer                 6    1,100                           
                 management               5    4,000                           
star books       management               5    1,500                           
                 miscellaneous            6   16,400                           
 
15 rows selected.
 
Here is the original SQL query that produced this report:
 
col pub_name   format a16
col book_type  format a15
col nbr_titles format 999,999
col sum_sold   format 999,999
 
break on pub_name
 
SELECT
   pub_name,
   book_type,
   count(*)      nbr_titles,
   sum(quantity) sum_sold
FROM
   publisher
natural join
   book
natural join
   sales
GROUP BY
   (pub_name, book_type)
;
 
 
Your exercise is to add the CUBE operator to calculate the aggregates and reproduce this report.  Note the aggregates for each publisher, and the grand total aggregates at the end of the report.
