Обсуждение: create view problem

dear sir,
i am trying to create view with following query

create view salesQ as
select * from sales, customer where sales.customerkey
= customer.customerkey;

it is giving

ERROR:  column "customerkey" duplicated

create view salesQ as
select sales.*, customer.* from sales, customer where
sales.customerkey = customer.customerkey;

also giving same error.
i cannot change field names or specify field names in
view definition because many fields are there in both
tables. how to create this view?

thanks in advance,
-Simon Moses,
Bangalore, India.

This has nothing to do with JDBC or Java, so it should not be sent to the
JDBC list.

You need to use aliases in your SELECT...

SELECT sales.customerkey AS salescustomerkey, customer.customerkey AS
customercustomerkey, ... FROM sales, customer WHERE ...
