Hi All,
I would like to design a hierarchical table that is similar to a geography 
table.  The challenge is that for some region you need to skip a level.  
Geography table has Country>State>City as hierarchy, but for some countries 
State is not present.  For example, United States>Texas>Houston contains all 
three levels, but UK>London does not contain state.  How can I design a table 
that can address the missing level?  Please note that table should reflect 
London at Level 3 instead of Level 2.

Thanks!
