4.44 SDO_TOPO_MAP.REMOVE_NODE
Format
SDO_TOPO_MAP.REMOVE_NODE( topology IN VARCHAR2, node_id IN NUMBER);
Description
Removes a node from a topology.
Parameters
- topology
-
Name of the topology from which to remove the node, or null if you are using an updatable TopoMap object (see Specifying the Editing Approach with the Topology Parameter). Must not exceed 20 characters.
- node_id
-
Node ID of the node to be removed.
Usage Notes
If topology
is not null, Spatial automatically updates the appropriate entries in the <topology-name>_NODE$ and <topology-name>_EDGE$ tables, and in the <topology-name>_FACE$ table if necessary. (If topology
is null, you can update these tables at any time by calling the SDO_TOPO_MAP.UPDATE_TOPO_MAP procedure.)
For information about removing a node from a topology, see Removing a Node.
Examples
The following example removes the node with node ID value 500 from the current updatable TopoMap object.
CALL SDO_TOPO_MAP.REMOVE_NODE(null, 500);
