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!

Oracle 9i reading an oracle 10g table and reciving End-of-file on communication channel error

Asked by Mike_Brinton in Oracle 9.x, Oracle 10.x, Oracle Database

Tags: oracle 9i, oracle 10g, sysdate, ora-03113, end-of-file on communication channel

Guidance please.  I am receiving an ORA-03113: end-of-file on communication channel when I run the first query listed below.  When I change the reference to 'SYSDATE' in the WHERE clause to a hard coded date, as in the second query, and the query executes correctly.  I am using 'SYSDATE' to build columns in both queries, and I am not having a problem when the WHERE clause has the hard coded date.  Also, I do not have a problem with the first query executing when I remove the condition in the warehouse clause with 'SYSDATE'.
Can someone please provide some suggestions at to what is causing the problem?
