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 trigger does not work.

Asked by PHD in MS SQL Server

Tags: microsoft, sql server 2000

Hello,

I have one table that point to themselve.
the PK is n_id and the FK is n_parent_id.

I have a trigger on that table after delete statement.
When a node is deleted I also delete childnode but if the child node have childnode I also need to delete them.

The trigger works fine for the first delete but if the first child have childnode the tigger is not fired.

I set the nested_trigger to 1 with sp_configure and when I execute sp_dboptions I see : "recursive triggers"

Did I forgot something ? Can you help me

             ALTER TRIGGER [dbo].[OnNodeDelete] 
   ON  [dbo].[syn_nodes] 
AFTER DELETE
as
BEGIN
	-- SET NOCOUNT ON added to prevent extra result sets from
	-- interfering with SELECT statements.
	SET NOCOUNT ON;
 
    declare @deleted_node_id int
    select @deleted_node_id = n_id from deleted
   
    delete from syn_nodes where syn_nodes.n_parent_id = @deleted_node_id //shoul trigger the samme trigger but does not
 
END
