Základní Spatial Operators
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.)
