Hello all,
New here and yes this is classwork. No I'm not looking for just the answer lol. I need to understand this, not just pass the class. Anyways, here is the ERD Im using, and just below it is the output I need. I can do each on its own but not together. Im sure I need the Group by, just haven't gotten it to work. I'm taking classes online and have emailed for help with no response, hence coming here. Any help appreciated Thanks
Create a customer report that lists all customer's names, the number of charters they have booked, and the total cost of all charters. Remember to include all customers, even customer’s that currently do not have any charters booked. |

SELECT TRIM(customer.cus_fname) ||
DECODE(customer.cus_initial,NULL, ' ',
' ' || customer.cus_initial || '. ')
|| TRIM(customer.cus_lname) "Customer Name",
COUNT(charter.char_trip) "# of Flights"
FROM xxx.customer
JOIN xxx.charter ON customer.cus_code = charter.cus_code
GROUP BY customer.cus_fname, customer.cus_initial, customer.cus_lname;
OUTPUTS this....
Customer Name # of Flights

James G. Brown 3

Olette K. Smith 1
Kathy W. Smith 2
Leona K. Dunne 4
Alfred A. Ramas 1

7 rows selected
So I got this part to work right after posting, but it does not list all customers. How could I add that? NULL I believe is what I want.... |

Use LEFT OUTER JOIN instead of INNER JOIN.
BTW, this forum is a Microsoft SQL Server forum, so expertise on other DBMSs are likely to be far and few in between. You will get better and faster responses for other DBMSs at a forum such as dbforums.com |
