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!

Dynamic sql in a cursor

Asked by williampeck in Oracle CRM, PL / SQL

Tags: Oracle, PL*Sql

I have very similar sql and code and want to consolidate.

but to do so I need a dynamic cursor where the table is set based on a value.

If this can be done, it would cut the code by about 1/2, a reasonable goal.

But if there is too much hoop-jumping for a little bit of savings, it's not worth it. The current code base is table and basically never changes. I am making a change to make the code more efficient, but once done, this will also be rarely changed code.

In the cursors below, the only difference is the table name

In the code below, the only difference is the cursor name reference.
