SDO_TOPO_GEOMETRY

Some parts in the output code are omitted for clarity reasons.

Description

This type describes a topology geometry, which is stored in a single row, in a single column of object type SDO_TOPO_GEOMETRY in a user-defined table. (Oracle SQL Language Reference SDO_TOPO_GEOMETRY Data Type).

Definition of SDO_TOPO_GEOMETRY object:

CREATE TYPE SDO_TOPO_GEOMETRY AS OBJECT
  (tg_type        NUMBER, 
   tg_id          NUMBER,
   tg_layer_id    NUMBER,
   topology_id    NUMBER);
/

The SDO_TOPO_GEOMETRY object is not supported in Snowflake.
