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!

Can this PL/SQL code be converted to just SQL?

Asked by shaynegw in Oracle Database

Tags: ,

Hi

I have the following Oracle PL/SQL update code that I would like to convert to regular SQL, is it possible? The intent is to add a surrogate unique key field (gis_seqno) that, for each record, represents the record number if the table were sorted differently, using three fields. I don't want to alter the table's current PK or physically alter the sort order of the base table, just add a new field.

---
declare
begin
for i in (select row_number() over (order by pco2.tx_ipy_acc_id,
                                                                pco2.tx_ipy_prt_id,
                                                                pco2.tx_prt_id) as row_number,
                        pco2.tx_ipy_acc_id,
                        pco2.tx_ipy_prt_id,
                        pco2.tx_prt_id
                   from pmo_customer_owner pco2
           ) loop
update pmo_customer_owner pco
   set pco.gis_seqno = i.row_number
 where pco.tx_ipy_acc_id = i.tx_ipy_acc_id
   and pco.tx_ipy_prt_id = i.tx_ipy_prt_id
   and pco.tx_prt_id = i.tx_prt_id;
end loop;
end;

Thanks and take care,
