Sdo_topo_map.Validate_topology Does Not Detect Duplicate Nodes In Topology (Doc ID 1119449.1)

Last updated on FEBRUARY 08, 2017

Applies to:

Oracle Spatial - Version: 10.2.0.4 and later   [Release: 10.2 and later ]
Information in this document applies to any platform.

Symptoms


Procedure SDO_TOPO_MAP.VALIDATE_TOPOLOGY is not catching when there is a duplicate node.

We have the case where the topology has two nodes with the same GEOMETRY (duplicate nodes) and the validation of the topology does not report this problem.

The documentation for SDO_TOPO_MAP.VALIDATE_TOPOLOGY does not specify if this checking is done, however, it seems we should be checking for duplicates.
