3 SDO_TOPO Package Subprograms

The MDSYS.SDO_TOPO package contains subprograms (functions and procedures) that constitute part of the PL/SQL application programming interface (API) for the Spatial Topology Data Model feature. This package mainly contains subprograms for creating and managing topologies.

To use the subprograms in this chapter, you must understand the conceptual information about topology in Topology Data Model Overview.

Note:

SDO_TOPO subprograms are not supported in Oracle Autonomous Database Serverless deployments.

Another package, SDO_TOPO_MAP, mainly contains subprograms related to editing topologies. Reference information for the SDO_TOPO_MAP package is in SDO_TOPO_MAP Package Subprograms.

The rest of this chapter provides reference information about the SDO_TOPO subprograms, listed in alphabetical order.
