Build directory structures using SQL Server 2005

(Tim Chapman) If you ever work with directory structures on the filing system, you know how challenging it can be to traverse through folders to find specific file(s). If you store this type of information structure in the database, you are even more aware of what it takes to retrieve the data. Writing queries to pull this information is sometimes difficult to achieve and inefficient. You can use the recursion and XML features in SQL Server 2005 to build a file location on the fly.
