Question

In the SQL Server 2012 there is methods to validate geography \'.IsValidDetailed()\' and to change orientation \'.ReorientObject (geography)\'.

I am working with SQ

Answer 1

This is working for me on SQL Server 2008. After loading the shape as a geometry, use MakeValid() to correct it, then reload into a geography.

declare @gt nvarchar(max)
declare @gm geometry
declare @gmvalid geometry

set @gmvalid = @gm.MakeValid()

  set @gt = @gmvalid.STAsText()

  --select @gt
  if LEFT(@gt,7 ) = 'POLYGON'
  begin
  set @gg = geography::STPolyFromText(@gt, 4326)
  end
  else
  begin
  set @gg = geography::STMPolyFromText(@gt, 4326)
  end
