Hi,
I have a web directory which allows sub-categories to an unlimited level.
This is done with a categories table, and assigning a parentid to each...
For example
ID ParentID Name
1 0 Products
2 1 Sub-Category of Products (Level 1)
3 1 Another Sub-Category (Level 1)
4 2 A sub-sub-category (Level 2)
What I need to do is return a list of an items parent categories. For
example, if we are in category 4, I want text outputted saying
Products \ Sub-Category\sub-sub Category
However, it does not seem possible to do this with a single SQL query. I
have succeeded in creating a recursive one below (in MS SQL):
CREATE PROCEDURE dbo.dir_recurse(@parentid INT) AS
--// List its parent categories
DECLARE @childid INT
DECLARE hC CURSOR LOCAL FOR SELECT parent FROM categories c WHERE id =
@parentid ORDER BY c.name FOR READ ONLY
OPEN hC
FETCH NEXT FROM hC INTO @childid
WHILE @@FETCH_STATUS = 0 AND @childid != 0
BEGIN
EXECUTE dir_recurse @childid
FETCH NEXT FROM hC INTO @childid
END
CLOSE hC
DEALLOCATE hC
RETURN 0
GO
However, this returns more than one result set, which neither ASP or PHP (so
therefore it's probably the ODBC driver...) seem to support. Help!
