Creating views from tables that have types in Oracle SQL Developer

Question

I am working with the oe schema in oracle sql developer and I need to create a view that joins multiple tables, some of which have types or "nested" attributes.

Is there a way to put those nested attributes into a different table or eliminate them entirely? I am a relative beginner and I cant seem to find a way or similar problem online.

Here is my query and I don't even know where to start with this, any help is appreciated.

Answer 1

There is no magic flag to exclude nested tables.

What you need to do is replace the * with the names of the columns you want to include. Yes that is a lot of typing but the bonus is your view has a coherent projection. At the moment your view has multiple instances of CUSTOMER_ID, ORDER_ID, PRODUCT_ID and CATEGORY_ID. That's illegal and confusing.
