SDO_LRS.SCALE_GEOM_SEGMENT
The following examples illustrate some SCALE_GEOM_ELEMENT uses. (These
examples use the definitions from the example in Section 7.7.)
-- Shift by 5 (for example, 5-mile segment added before original start)
SELECT SDO_LRS.SCALE_GEOM_SEGMENT(a.route_geometry, m.diminfo, 0, 27, 5)
FROM lrs_routes a, user_sdo_geom_metadata m
WHERE m.table_name = 'LRS_ROUTES' AND m.column_name = 'ROUTE_GEOMETRY'
AND a.route_id = 1;
