Format

SDO_NET.TOPO_GEOMETRY_NETWORK(      
  network  IN VARCHAR2      
) RETURN VARCHAR2;

Description

Returns the string TRUE if the network is a spatial network containing SDO_TOPO_GEOMETRY (topology geometry) objects; returns the string FALSE if the network is not a spatial network containing SDO_TOPO_GEOMETRY objects.

Parameters

network

Network name.

Usage Notes

A network contains SDO_TOPO_GEOMETRY objects if the GEOMETRY_TYPE column in its entry in the USER_SDO_NETWORK_METADATA view contains the value TOPO_GEOMETRY. (The USER_SDO_NETWORK_METADATA view is explained in xxx_SDO_NETWORK_METADATA Views.)

Examples

The following example checks if the network named ROADS_NETWORK is a spatial network containing SDO_TOPO_GEOMETRY objects.

SELECT SDO_NET.TOPO_GEOMETRY_NETWORK('ROADS_NETWORK') FROM DUAL;
 
SDO_NET.TOPO_GEOMETRY_NETWORK('ROADS_NETWORK')
