I am a newbie in SQL Server 2008 and just got introduced to HierarchyId's.
I am learning from SQL Server 2008 - HIERARCHYID - PART I. So basically I am following the article line by line and while practicing in SSMS I found that for every ChildId some hexadecimal values are generated like 0x,0x58,0x5AC0 etc.
My questions are
- What are these hexadecimal values?
- Why are these generated and what is their use? I mean where can I use those hexa values?
- Do we have any control over those hexa values? I mean can we update etc.
- How to determine the hierarchy by looking into those hexa values.. I mean how can I determine which is the parent and which is the child?
Thanks in advance
