SQL Server Stored Procedure (Menu System) - Microsoft SQL Server 2005 - sql-server

Question

Suppose - I have the following Table Structure
elementid, parentid, elementtitle, sortorder
160 0 Brand New Tutorial 1
161 160 Brand New Tutorial New Step 1
168 5 Tutorial Topic 1.1 1
171 168 Tutorial Topic 1.1.1 1
172 171 Tutorial Topic 1.1.1.1 1
I need to be able to setup a Stored Procedure that will allow me to Update the Elementid's, Parentid's relationship.
Here is my Normal SQL For Generating the tree:
WITH menu AS
(
SELECT parentid, elementid, elementtitle, sortorder FROM dbo.ta_tutorial_elements WHERE (elementid = #eid)
UNION ALL
SELECT e.parentid, e.elementid, e.elementtitle, e.sortorderFROM dbo.ta_tutorial_elements AS e INNER JOIN menu AS m ON e.parentid = m.elementid
)
SELECT * INTO [#tmpA] FROM menu
I believe it could be possible to use temp tables to copy the table over and then somehow use the identity of the insert into my standard table to start with the elementid and the root parent...however, after that I am pretty much lost on how to recursively udpate all parentid's, elementid's with their relationships...(is it possible in SQL Server?).
I am seeing something like the following:
CREATE PROCEDURE [dbo].[sp_ta_copy_tutorial_by_id]
#eid bigint
AS
SET nocount on
BEGIN
DECLARE #recid bigint
SET #recid = (SELECT IDENT_CURRENT('ta_tutorial_elements'));
WITH menu AS
(
SELECT parentid, elementid, elementtitle, sortorder, userid, createddate FROM dbo.ta_tutorial_elements WHERE (elementid = #eid)
UNION ALL
SELECT e.parentid, e.elementid, e.elementtitle, e.sortorder, e.userid, e.createddate FROM dbo.ta_tutorial_elements AS e INNER JOIN menu AS m ON e.parentid = m.elementid
)
SELECT * INTO [#tmpA] FROM menu
ALTER TABLE [#tmpA]
DROP COLUMN elementid
SELECT * INTO [#tmpB] FROM [#tmpA];
UPDATE b SET b.parentid =
CASE
WHEN b.parentid <> 0
THEN #recid
ELSE 0
END
FROM [#tmpB] as b
INSERT INTO [ta_tutorial_elements] SELECT * FROM [#tmpB]
DROP TABLE [#tmpA]
DROP TABLE [#tmpB]
END

Answer 1

Check out CTEs (common table expressions). You can use a CTE within the context of a stored procedure to yield your menu data after some recursion. Actually it looks like you already have a CTE; the link describes recursion within that context.
