When spatial tables are created directly in the database (outside of ArcGIS), each record in a spatial table can be assigned a different SRID and spatial reference. When data is pasted or imported into a database or enterprise geodatabase using ArcGIS, ArcGIS takes the well-known text description and ID of the coordinate system of the incoming data, along with the tolerance and resolution if present, and compares it to values in the spatial reference system table. The Attribute Filtering page is displayed. Making statements based on opinion; back them up with references or personal experience. Select Poll for New or Changed Records in a Table and click Next.
