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!

SQL Case statement in Where clause

Asked by clickclickbang in SQL Server 2005, MS SQL Server, SQL Query Syntax

Tags: , , , ,

Dear experts, I am trying to use Case logic to a where statement in my stored proc. I have a Messages table that has messages a user has sent to himself or other people. I need some kind of If statement to decide what type of blnDeleted column to use. Currently i have a blnSenderDeleted and blnRecipientDeleted column. if the user is the sender of the message then a i need to check for blnSenderDeleted if the user if the recipient then i need to check for blnRecipientDeleted
I am also using SQL to handle paging.

Exmaple script:
SELECT *
FROM
      (SELECT *, ROW_NUMBER() OVER(ORDER BY Message_ID) as RowNum, @Total as Total
       FROM Messages m
       Join LoggedInToken lt on m.Recipient_ID = lt.Member_ID
       WHERE lt.Token = @Token AND 0 = Case                                           When @MemberID = m.Sender_ID then                                      m.blnSenderDeleted                                          else                                                    m.blnRecipientDeleted                                          End
        blnSenderDeleted = 0 AND Type = 'Message'
) as MsgList
WHERE RowNum BETWEEN @startRowIndex AND (@startRowIndex + @maximumRows) - 1  order by dteCreated DescStart Free Trial
