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!

Nested Case Stmts

Asked by newbie46 in SQL Server 2008

I am writing an SQL function:
Returns Table
AS
Return
(
Select X AS Id,
   Max(Case When A = N'Apple' Then N'Apple' Else Null End) AS Apple,
   Max(Case When B = N'Bat' Then N'Bat' Else Null End) AS Bat
From ....
Where ...
Group By...
)

I want to add an If stmt or another case so that it will determine which Max Case to execute.
For example, conceptually it would look like:

Select X AS Id,
 IF Group1 = 'A' then
   Max(Case When A = N'Apple' Then N'Apple' Else Null End) AS Apple,
end if
IF Group1 = 'B' then
   Max(Case When A = N'Bat' Then N'Bat' Else Null End) AS Bat
end if
From ....
Where ...
Group By...

How can this be done?
Thanks.
