SQL Server 2008 Hierarchy Data Type Performance? -
Which describes the hierarchy data of SQL Server 2008 as compared to the hierarchy implementation described by Selco:?
I have used the method of Selco in the past with great results - but as long as it is provided in SQL Server 2008, it is not better unless it applies to the new project Do not want to.
So far, I have found only an interesting article on the subject. The hierarchy is much faster than any self-made self-referenced table solution:
I remember a little more comparison than any other comparison (but now it can not be found) Who came on similar conclusions; Using hierarchy to build a hierarchy is a bit of a burden on the best, but query execution is stellar.
