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!

Evaluating variable from PL/SQL procedure in SQL*Plus

Asked by ThinkApps in Oracle 3rd Party Tools

Tags: oracle

Hi all,

I want to run an update script for my Oracle 8i database in SQL*Plus which checks some data and run other scripts. The code looks like the following:

CREATE OR REPLACE PROCEDURE check_table (RESULT OUT NUMBER)
AS
   invalid_data   EXCEPTION;

   CURSOR l_cur
   IS
      SELECT DISTINCT * FROM some_table WHERE some_column='x';
BEGIN
   RESULT := 0;
   FOR l_rec IN l_cur
   LOOP
      RESULT := RESULT + 1;
   END LOOP;

   IF RESULT > 0
   THEN
      DBMS_OUTPUT.put_line ('Invalid data.');
      RAISE invalid_data;
   ELSE
      DBMS_OUTPUT.put_line ('Ok.');
   END IF;
EXCEPTION
   WHEN invalid_data
   THEN
      NULL;
   WHEN OTHERS
   THEN
      DBMS_OUTPUT.put_line (   'Exception in procedure check_table(): '
                            || DBMS_UTILITY.format_error_stack ()
                           );
END;
/

VARIABLE ret_val char
EXEC check_table(:ret_val);


This runs fine so far. Now I need something like
 if ret_val > 0 then exit
else
@@the_next_script.sql

I.e. if the check data procedure finds invalid data, the script execution shall terminate. Otherwise it shall continue and run some other update scripts. I do not want to put all the code into one (this particular update) script as there is a lot code to execute and the other scripts are standard scripts which are run at periodical points of database updates, such as recompilation of objects etc..

Thanks for any help
