Special notes on support and compliance

This section describes any special notes about SQL Anywhere support of spatial data including unsupported features and notable behavioral differences with other database products.

  • Geographies and geometries   Some vendors distinguish spatial objects by whether they are geographies (pertaining to objects on a round-Earth) or geometries (objects on a plane or a flat-Earth). In SQL Anywhere, all spatial objects are considered to be geometries, and the object's SRID indicates whether it is being operated on in a round-Earth or flat-Earth (planar) spatial reference system.

  • Unsupported methods  

    • ST_Buffer method
    • ST_LocateAlong method
    • ST_LocateBetween method
    • ST_Segmentize method
    • ST_Simplify method
    • ST_Distance_Spheroid method
    • ST_Length_Spheroid method
