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 multiple rows with Max value

Asked by rodgerthedodger in MS SQL Server

Tags: max, multiple, rows, value


My data table has duplicate values which have been extracted into a workfile. The ID column in the data table below is just a device to allow for subsequent grouping on the GROUP field; it doesn't matter which GROUP value is to be selected ie. top, middle or low as long as the update sets each of the three rows to the same GROUP value. Each of the three fields is in char format. Most of the 'duplicate' rows have only two GROUPS; none have more than three.

CODE      GROUP            ID

ABC             TOP                ABC123        
ABC               MIDDLE          ABC123    
ABC              LOW            ABC123    

I've tried using the MAX() function but this comes up against the problem of aggregating multiple values? How I can update the workfile so that I end up with only one row?
Thanks
