Query Using Joins.Please Help

Question

Hi,
A Query please
I have a Customer table and an Order Table
The customer can place multiple orders
Create Table Customers
(Cust_id      number(2),
cust_name    varchar2(15),
constraint   pk_custid PRIMARY KEY(Cust_id)
Create Table Orders
(Order_no    number(2),
Cust_id     number(2),
order_status varchar2(1),
constraint  pk_orderno PRIMARY KEY(order_no),
constraint  fk_custid  FOREIGN KEY(cust_id)
REFERENCES  Customers(cust_id)
)Now,the Customer table has a single record
whereas the Order Table has multiple records
for the same customer.
SQL> Select * from Orders
ORDER_NO   CUST_ID ORDER_STATUS
        1         1 P
        2         1 PI'd like to view the different orders for that same customer
Using a simple Join DOES NOT give the right output:
SQL> Select C.cust_id,C.cust_name,
  2  O.order_no,O.order_status
  3  From Customers C,Orders O
  4  where C.cust_id = O.order_no;
  CUST_ID CUST_NAME        ORDER_NO O
        1 ABCD              1       PThere are 2 records in the Orders Table?
How to view both the records from Orders Table?
Do I need to use the EXISTS clause?
Can someone please help?

Answer 1

Well, I would have thought that you would join C.cust_id with the O.cust_id (and not O.order_no)???
SQL> Select C.cust_id,C.cust_name,
  2  O.order_no,O.order_status
  3  From Customers C,Orders O
  4  where C.cust_id = O.order_no;
