I have a table containing 2D object-relational geometries migrated from a
relational spatial schema
using SDO_MIGRATE.TO_81X - they look like this.
SDO_GEOMETRY(1, NULL, SDO_POINT_TYPE(2210633.78, 387061.732, NULL), NULL,
NULL)
SDO_GEOMETRY(2002, NULL, NULL, SDO_ELEM_INFO_ARRAY(1, 2, 1),
SDO_ORDINATE_ARRAY(2224432.27, 390604.128, 2224107.25, 390600.734))
Is there a procedure or function to convert to 3D points (All 0 Zs) so I can
combine these geometries with a table
having existing 3D geometries and rebuild the spatial index? My 3D
geometries look like this.
SDO_GEOMETRY(3001, NULL, SDO_POINT_TYPE(1880228.3, 687409.4, 0), NULL, NULL) SDO_GEOMETRY(3002, NULL, NULL, SDO_ELEM_INFO_ARRAY(1, 2, 1), SDO_ORDINATE_ARRAY(1883801.1, 685705.9, 0, 1883771, 685751.7, 0))
thanks,
steve
