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 Select (SQL) - Question about eliminating duplicates

Asked by ktylerconk in Oracle 10.x

I have to do a select where I am summarizing the the lost items by last name for a particular month.  When I do a straight SUM on LOST I get twice the number that I need because I have 2 recs for each SHIP_DATE since the item could be delivered the next day, or the folliwng day.  How can I code the SELCT so that I only pick up the first number on lost for a SHIP_DATE, LAST_NAME combination?

SHIP_DATE      LAST_NAME      CITY      STATE      ZIP       LOST       DT1_DOW      
Jan/29/2008      ROBINSON      BALTIMORE      MD      21230-4241       1.00      THU       
Jan/29/2008      ROBINSON      BALTIMORE      MD      21230-4241       1.00      FRI       Jan/30/2008      ROBINSON      BALTIMORE      MD      21230-4505       1.00      FRI       Jan/30/2008      ROBINSON      BALTIMORE      MD      21230-4505       1.00      SAT       Jan/31/2008      ROBINSON      BALTIMORE      MD      21230-4526       1.00      SAT       Jan/31/2008      ROBINSON      BALTIMORE      MD      21230-4526       1.00      SUN       

Also, the SHIP_DATE resides in the database in the format 'DD MON YYYY'.  I want to group by Month. How would I code this month field so that this is grouped my Month?
