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!

Before insert trigger still inserting

Asked by ShaunMarion in Oracle Database

Tags: insert, do, raise_application_error, trigger

I have a trigger that fires evertime rows are inserted into the db, if that record allready exists, it just adds one to a tall field.  This all works fine and dandy, however after the trigger is fired, it still inserts the new row, I want to stop this from happening.  Here is my code so far, I have tried several different methods and all produce the sam outcome:

CREATE OR REPLACE TRIGGER NEW_FIVEESS_MESSAGE
BEFORE INSERT
ON FIVEESS_MESSAGE_COUNT
REFERENCING NEW AS NEW OLD AS OLD
FOR EACH ROW
DECLARE
        ex EXCEPTION;
        PRAGMA EXCEPTION_INIT(ex, -20001);
BEGIN
        IF (:NEW.tally IS NULL) THEN
                INSERT_MESSAGE_COUNT(:NEW.occurrence, :NEW.hour, :NEW.message, :NEW.switch);
                dbms_output.put_line('new tally wasnt null');
        ELSE
                dbms_output.put_line('new tally was null');
        END IF;

        RAISE_APPLICATION_ERROR(-20001, 'Do Nothing With This');

        EXCEPTION
                WHEN ex THEN
                        dbms_output.put_line('Exception caught');
END;
/
show errors;
