HierarchyID Data type, sp_spaceused

HierarchyID Data type - enables a tree structure, modeling an organizational structure, representing of a file system, representing a set of tasks in a project, modeling a graph of links between web pages.

Methods
child.GetAncestors(n) - returns a hierarchyid representing the nth ancestors
parent.GetDescendant(child1, child2) - returns a child node
node.GetLevel() - returns an integer value representing the depth of the node in the tree.
HierarchyID::GetRoot() - returns the root of the herarchy
parent.IsDescendant(child) - is used to find out if a node is descendant of another node
HierarchyID::Parse(input) - converts a string representation of a herarchyid to a herarchyid value
node.Reparent(oldRoot, newRoot)
node.ToString()

create table tblFolders(OrgNode HierarchyID, FolderName VARCHAR(MAX))

--insert root
INSERT INTO tblFolders(OrgNode, FolderName) VALUES(HierarchyID::GetRoot(),'C:\')

--insert second row-child of root folder
DECLARE @Root HierarchyID;
SELECT @Root = HierarchyID::GetRoot() FROM tblFolders;
INSERT INTO tblFolders(OrgNode, FolderName) VALUES(@Root.GetDescendant(NULL, NULL),'C:\Program Files')

--insert third row-child of root folder
INSERT INTO tblFolders(OrgNode, FolderName) VALUES(@Root.GetDescendant(CAST('/1/' AS HierarchyID), NULL),'C:\windows')

--insert a child for the 'C:\Program Files' folder
DECLARE @Parent HierarchyID;
SELECT @Parent = CAST('/1/' AS HierarchyID)
INSERT INTO tblFolders(OrgNode, FolderName) VALUES(@Parent.GetDescendant(NULL, NULL),'C:\Program Files\Microsoft SQL Server')

Table-valued parameters

Table-valued parameters - allows you to use multiple rows of data in T-SQL statments or send a table as a parameter to functions and stored procedures. It benefits such as flexibility, better performance than other methods of passing list of parameters adn reduce round trips to the server.The user-defined table type used for the table-valued parameters.

ASP.NET Custom Errors(customErrors) and URL Mappings (urlMappings)

URL Mappings
  1. Open web.config file. (see MSDN)
  2. Create new urlMappings section within the system.web section.
  3. <urlMappings enabled="true">
    <add url="~/contactus.aspx" mappedUrl="~/index.aspx" />
    </urlMappings>
  4. If user types contactus.aspx, page mapped to the index.aspx.
  5. This approach won't work if you have 100 of pages to map.
  6. Best solution is to use regular expressions, but ASP.NET does not support. SEE

Debug Directive

If the code is only for development environment not in the live or release environment use Debug Directive or Conditional attribute For exmple, Some of the code only run while in debugggin mode, but you don't want to shift to production server or code to run while in live

If the application/compilation running in the debug mode, then the debug code will execute, but if you complied the same code in the release mode, then debug code will not execute.

In Debug environment, output is
If Debug
No If
Conditional Debug
No Conditional
