i have this case using recursive query on Mysql to find lv 2 and lv3 child on one table... database structure i'm using: id name parent 1 A 0 2 B 0 3 C 0 4 D 1 5 E 1 6 F 2 7 G 2 8 H 3 9 I 3 10 J 4 11 K 4 The result i was expecting, when filtering the data, where id=1, it will generate the result i'm expecting. id name parent 4 D 1 5 E 1 10 J 4 11 K 4 or this is the illustration. i've been looking everywhere, and reading this http://mikehillyer.com/articles/managing-hierarchical-data-in-mysql/ , but i didn't find the result i was looking for.. any help would be appreciated, thanks SELECT * FROM

I am currently trying to figure out a good way to sort my elements with LINQ and C#, but I am kinda failing to do so. For the problem let assume you have the following Table ---TempTable ID (int) ParentID (int) Name (varchar) SortOrder (int) The ID and ParentID are related to each other and give me a self hierachical data structure. The root elements have a null in the ID Field. The SortOrder is only a portion of the whole table and based on the ParentID, so the elements that share the same ParentID do have 1, 2, 3 in it. Lets further assume the following data: ID = 1 ParentID = null Name =

I want to change the default template hierarchy behavior, and force all subcategory level pages that don't have their own category template file to refer to their parent category template file. In my other post, Richard M. gave an excellent answer that solved the problem for an individual subcategory. Does anyone know how to abstract it? function myTemplateSelect() { if (is_category()) { if (is_category(get_cat_id('projects')) || cat_is_ancestor_of(get_cat_id('projects'), get_query_var('cat'))) { load_template(TEMPLATEPATH . '/category-projects.php'); exit; } } } add_action('template_redirect'

I need to display a Treeview in my MVC3 application. There will be a self referencing hierarchical table (Folders) and another table linked to it (Documents.) (So Folders can have N-subFolders and any folder/sub folder can have many documents.) I have looked into using third party vendors such as Telerik, DJME and MVC Controls Toolkit. While all nice packages, I'm uneasy about the licences, and since i'm new to MVC (and programming in general,) I find their documentation lacking to get the right display working. I've also looked at the heavily referenced blogs on TreeViews: TreeViewHelper and

I have some json that I would like to parse in SQL Server 2016. There is a hierarchy structure of Projects->Structures->Properties. I would like to write a query that parses the whole hierarchy but I don't want to specify any elements by index number ie I don't want to do anything like this: openjson (@json, '$[0]') or openjson (@json, '$.structures[0]') I had this idea that I could read the values of the top level project objects along with the json string that represents the structures below it, which could then be parsed separately. The problem is that the following code does not work:

Basic deal is, we have a custom built "kickstart" for our projects. For this we are looking at redoing the user control. I know there are a lot of questions out there about general rbac, but I cannot find any on hierarchical rbac? Our requirements are: Roles can be assigned to group permissions If the role does not have a permission entry then it is automatically denied A user can be given overriding permissions A users overriding permissions is either a grant or deny If a user is explicitly denied a permission no matter what roles say "granted" the override wins. Users can have multiple roles
