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!

How to join 2 SQL tables without primary key

Asked by Pharmica in SQL Query Syntax, SQL Server 2005

Tags:

Greetings Experts.

How do I join 2 tables where there is no primary key.  There is way to determine each record uniquely by using a combination of 2 fields, for example

Table1                                  
Study         Site        CRA <---column headings
INOT11       001        Ben
INOT11       002        Bill
INOT11       003       Jen
INOT20       001        Jeff

Table2
Study         Site      Category            Count
INOT11       001        Unreviewed        50
INOT11       001        Closed                21
INOT11       001        Pending              10
INOT11       001        Resolved            9

I am looking to combine both tables on Study and site, then determine the COUNT of unreviewed only.  So my output would look like this,

Study         Site        Category            Count       CRA
INOT11       001     Unreviewed             50         Ben

I cant figure it out.  Your help is greatly appreciated.  Thanks.
