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!

Clever SQL Query

Asked by troyholland in SQL Server 2005

Tags: sql, clever, query

Howdy,

I'm having trouble coming up with a 'clean' way of selecting some records. I have two tables. One is the user table, and the other is a list of books the user has read. I'm trying to find all the users that have read a list of books and rated each book 4 or more. The basic table looks like this:

CREATE TABLE BooksRead (
   UserId int NOT NULL,
   BookId int NOT NULL,
   Rating int NOT NULL
)

For example: Which users have read books 2, 8, 12, 35, 36 and rated all of them 4 or more.

I can get the script to work by having multiple joins to the BooksRead table, but I'm not going to have the same number of books in each query. The next query could have 8 books with a rating of 3 or more. I'd like the script to be a little more dynamic and flexible. There's got to be a clever way to write this.

Cheers,
Troy
