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!

Selecting data from two consecutive rows.

Asked by awking00 in Oracle Database

Tags: consecutive

I have a table that is ordered by id and tax_period with the following structure:
 id varchar2
,tax_period date
,related_period date

My question is how can I select the related_period value from a given row and the related_period value of the subsequent (or previous) row simultaneously, when the id values are the same and the tax_period values are different by fewer than twelve months? I have been able to determine the values using a self join, but the table contains approximately 30 million rows and does not perform well. I appreciate any ideas.
