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!

Grouping with Dates ~ Problem with Dupes in Query

Asked by Roxanne25 in SQL Server 2005, SQL Query Syntax

Hi, I am working with a large query and I'm having trouble with duplicates when doing grouping.

Data looks like this:

ORDER NUMBER              LINE NUMBER              PROMISE DATE             REVENUE                  COST
ORD123                          1                                 5/1/2007                      100.00                      50.00
ORD123                          2                                 NULL                             200.00                     100.00

Trying to group the data at the order header level.  However, this promise date field is causing me a lot of problems.  I tried doing MAX() on the promise date, but it yelled at me for having NULLs and it basically didn't do anything.

I then wrote a case statement to put 12/31/1900 as the date if the date was null.  Then I wrote a second query off that to pull the max() again...it still returned 2 rows...

What am I doing wrong and how do I get it to group this?
