Recursive Stored Procedure

[fabiomoggi]

Hello Guys,

I am developing a web application to manage Active Directory resources, and one of my tasks is to map Organizational Units hierarchy into a SQL Server database. Let's suppose that I have the following OU hierarchy in my Active Direcoty:

1. NewYork
1.1 HR_Department
1.1.1 Computers
1.1.2 Users
1.2 SALES_Departmen t
1.1.1 Computers
1.1.2 Users
1.3 So on.....
2. Chicago
2.1 HR_Department
1.1.1 Computers
1.1.2 Users
2.2 SALES_Departmen t
2.1.1 Computers
2.1.2 Users
2.3 So on....

I designed the following table into SQL Server in order to reach the AD hierarchy:

OUId INT
// Just an integer ID to identify the row.

OUName VARCHAR(50)
// Name of OU that comes from AD.

ParentOUId INT
// Id of the parent OU to create as many levels as necessary.

The idea is to create a recursive table to store the hierarchy in a flexible way that there won't be any limitations in terms of creating as many sub OU as necessary. At this point goes my issue: I am having problems to create a store procedure to return whether a OU already exists or not.

Unfortunately Active Directory does not provide me a property that indicates who is parent OU. I can only identify the object structure by the distinguishedNa me property, which acording to my example returns something like:

OU=Computers,OU =HR_Deparment, OU=NewYork, DC=....

From this string, I convert it to an array:

[0] Computers
[1] HR_Department
[2] NewYork

From now on, I am stuck. I don't know how to create a recursive procedure or function in the context to return and create the AD Hierarchy.


Could anyone help with it?

Thank you very much for you attention!

I'd say use XML

Hi,

Thank you for the answer!

I don't know how to approach it using XML.

Could you help me on how to start it?
