Finding Physical Row Location

Wayne Sheffield shows how to find the physical location of a row in SQL Server:

Acquiring the physical location of a row

SQL Server 2008 introduced a new virtual system column: “%%physloc%%”. “%%physloc%%” returns the file_id, page_id and slot_id information for the current row, in a binary format.

Read on for two functions you can use to format this data more nicely, as well as a short re-write Wayne did to improve performance of one of them.
