To create a view 'ordersview' by three tables 'orders', 'customer' and ' agents' with following conditions -

1. 'a' and 'b' and 'c' are the aliases of 'orders' and 'customer' and 'agents' table,

2. 'cust_code' of 'orders' and 'customer' table must be same,

3. 'agent_code' of 'orders' and 'agents' table must be same,

the following SQL statement can be used:

CREATE VIEW ordersview
AS SELECT ord_num, ord_amount, a.agent_code,
agent_name, cust_name
FROM orders a, customer b, agents c
WHERE a.cust_code=b.cust_code
