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!

Extract data from duplicate records before removing

Asked by WPHIT in Microsoft Access Database, SQL Query Syntax, Databases Miscellaneous

Tags: Microsoft, Access, 2003

Ok, I'll try and explain this so it makes sense!

I've been given a data extract to tidy up.  It contains records relating to our clients, each of whom has a 'Person Reference'.  However, the table has up to six duplicate records for each client.

The problem is that each duplicate record has a different entry in a field called 'Disability', since lots of clients have more than one disability.  What I need to do is 'move' these various entries into new fields ('Disability 1', 'Disability 2' etc.) in the first record before I delete the duplicates so that I'm left with one record for each client with each of their disabilities in a separate field within that record.

I know how to do this if I can design a query to extract just the second duplicate of each record, then another to extract just the third duplicate, just the fourth and so on, but so far I can't work out how to do this.
