Figure 24–3 SDO_GEOM.SDO_INTERSECTION
SDO_GEOM.SDO_INTERSECTION
An exception is raised if geom1 and geom2 are based on different coordinate systems.
The following example returns a geometry object that is the topological intersection
(AND operation) of cola_a and cola_c. (The example uses the definitions and data
from Section 2.1.)
-- Return the topological intersection of two geometries.
SELECT SDO_GEOM.SDO_INTERSECTION(c_a.shape, c_c.shape, 0.005)
FROM cola_markets c_a, cola_markets c_c
WHERE c_a.name = 'cola_a' AND c_c.name = 'cola_c';

Note that in the returned polygon, the SDO_ORDINATE_ARRAY starts and ends at
the same point (4, 5).
