What are the basic that one should know about geometry datatype? How is it computed ? Why do we need geometry data type?
Edit: I wanted to know why there is a different datatype called geometry. Is geometry some basic data type plus location information or more! How to understand the data in this column?
From MSDN: The planar spatial data type, geometry, is implemented as a common language runtime (CLR) data type in SQL Server. This type represents data in a Euclidean (flat) coordinate system.
