Základní Spatial Operátory

Operator         Description

SDO_FILTER       Specifies which geometries may interact with a given geometry.
SDO_JOIN         Performs a spatial join based on one or more topological relationships.
SDO_NN           Determines the nearest neighbor geometries to a geometry.
SDO_NN_DISTANCE  Returns the distance of an object returned by the SDO_NN operator.
SDO_WITHIN_DISTANCE Determines if two geometries are within a specified distance from one another.
SDO_RELATE       Determines whether or not two geometries interact in a specified way. (See for convenient alternative operators for performing specific mask value operations.)
