in the package SDO_GEOM
supplies as a result the positional relationship between two objects. c2.feature_name, sdo_geom.relate (c2.geometry, 'Determine' - masking parameters c1.geometry, 0.05) select from topo_rel m_admin_area1 c1, c2 m_admin_area1 where c1.feature_name = 'GERMANY'; The value
DETERMINE determined for the masking parameters while those spatial relationship between two objects, which correspond to reality at the most.In the case of the above query is determined by the free sample data sets provided
NAVTEQ for Oracle the positional relationship between Germany and other countries.
