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!

Cannot EXTEND Nested Table Collection in OBJECT

Asked by mjzalewski in Oracle Database

Tags: , ,

What is wrong with the following (Oracle 8i and Oracle 9.2)

CREATE OR REPLACE TYPE OrderDetail AS OBJECT(
  Line NUMBER,
  Description VARCHAR2( 35),
  Qty NUMBER,
  Price NUMBER
);
/
CREATE OR REPLACE TYPE OrderDetailTable AS TABLE OF OrderDetail;
/
CREATE OR REPLACE TYPE OrderDetails AS OBJECT(
  m_Details OrderDetailTable,
  MEMBER PROCEDURE clear,
  MEMBER FUNCTION addItem( p_Line IN NUMBER, p_Description IN VARCHAR2
        , p_Qty IN NUMBER, p_Price IN NUMBER)
    RETURN NUMBER
);
/
CREATE OR REPLACE TYPE BODY OrderDetails AS
  MEMBER PROCEDURE clear IS
  BEGIN
    m_Details := OrderDetailTable();
  END;
  MEMBER FUNCTION addItem( p_Line IN NUMBER, p_Description IN VARCHAR2
        , p_Qty IN NUMBER, p_Price IN NUMBER)
    RETURN NUMBER IS
    v_Size NUMBER;
  BEGIN
    m_Details.EXTEND; -- Error here
    v_Size := m_Details.LAST;
    RETURN v_Size;
  END;
END;
/

The TYPE BODY gives the following error

LINE/COL ERROR
-------- -----------------------------------------------------------------
11/5     PLS-00363: expression 'SELF.M_DETAILS' cannot be used as an
         assignment target

11/5     PL/SQL: Statement ignored


Line 11 is m_Details.EXTEND; -- it's not an assignment at all.

Is there another way to accomplish this (having a collection inside an object. It must work in Oracle 8i).
