Hi sa_84,  To convert to SqlGeometry you need to create a new Column in your table e.g

ALTER TABLE [schemaname].[tablename]
ADD [Geom] Geometry

then you can do (this assumes the database has mssqlspatial installed - mssqlspatial stores wkb with extra info):

UPDATE [schemaname].[columnname]
SET [Geom] = geometry::STGeomFromWKB(ST.AsBinary(WKB_Geometry), ST.Srid(WKB_Geometry))

or (if the database does not have mssqlspatial installed and WKB_Geometry is OGC standard):

DECLARE @epsgcode
SET @epsgcode = 4326 /* update to the correct epsg code for your data */

UPDATE [schemaname].[tablename]
SET [Geom] = geometry::STGeomFromWKB([WKB_Geometry], @epsgcode)
