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_RELATE

Determines whether or not two geometries interact in a specified way. (See also Table 19-2 for convenient alternative operators for performing specific mask value operations.)

SDO_WITHIN_DISTANCE

Determines if two geometries are within a specified distance from one another.
