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!

Recursive SQL Functions (Syntax)

Asked by ApxMike in MS SQL Server, SQL Server 2005

Tags: SQL Recursive Functions

I have tried to create recursive fuctions with MS SQL 2000 and 2005, and have not been sucessfull.  I have tried numerous ways and examples from online, none of which have worked.

Below are two examples which do not work on either of my machines.  (the + sign doesnt show correctly).

If anyone has experience with recursive SQL procedures I would appreciate your assistance.

Thanks!

Attempt I wrote:
 
CREATE FUNCTION TestSum
(
	@i int,
	@sum int
)
RETURNS int
AS
BEGIN
	SET @sum = @sum + @i
 
	if (@i > 1) begin
		return TestSum(@i - 1, @sum)
	end
	else begin
		RETURN @sum
	end
END
 
 
 
 
 
Example from online:
create function RecursiveTest(@V int)
returns @t table (i int)
as
   begin
   set @v = @v - 1
   if @v<>0
     insert into @t 
     select @v union 
     select * from RecursiveTest(@v)
   else
     insert into @t values (0)
   return
   end
 
select * from RecursiveTest(10)
