The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Properties of VIEW objects in Oracle

Asked by mmm03 in Oracle Database

Tags: , ,

I want to know the properties of VIEWS in Oracle.
How does it "select" the result?

Here is the scenario:

I have table TEMP with fields field_1, field_2.

I have a view that is defined by:
        CREATE VIEW TEMP_VW AS SELECT field_1, field_2, dummy_function('DUMMY') FROM TEMP;
where dummy_function(VARCHAR) is a URL Call (UTL_HTTP).

Now, what I did is turned off the URL being called. ( turned off in the sense that you would not be able to access it )
When I try to query:
                                               select field_1 from temp_vw;
it returns a successful result.

but when I select:
                                               select field_1, dummy_function('DUMMY') from temp_vw;
it returns a UTL_HTTP error that it can't access the URL.

Now my question is, why is it successful in the first scenario?

Thanks.
