title: What is SRID 0 for geometry columns?
body: <p>So I added geometry columns to a spatial table and using some of the msdn references I ended up specifying the SRID as 0 like so:</p>
  
  <pre><code>  update dbo.[geopoint] set GeomPoint = geometry::Point([Longitude], [Latitude], 0) 
  </code></pre>
  
  <p>However, I believe this was a mistake, but before having to update the column, is 0 actually the default = 4326?  The query works as long as I specify the SRID as 0 on the query, but I'm getting weird results in comparison to the geography field I have...  SRID 0 does not exist in sys.spatial_reference_systems and I haven't been able to dig up any information on it.  Any help would be appreciated.</p>
