6.100 SDO_NET.TOPO_GEOMETRY_NETWORK
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.
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') -------------------------------------------------------------------------------- FALSE
