SDO_LRS.DYNAMIC_SEGMENT
Usage Notes
Examples
dim_array
Dimensional information array corresponding to geom_segment, usually selected
from one of the xxx_SDO_GEOM_METADATA views (described in Section 2.4).
start_measure
Start measure of the geometric segment.
end_measure
End measure of the geometric segment.
tolerance
Tolerance value (see Section 1.5.5 and Section 7.6).
An exception is raised if geom_segment, start_measure, or end_measure is
invalid.
The direction and measures of the resulting geometric segment are preserved.
For more information about clipping a geometric segment, see Section 7.5.3.
The following example clips the geometric segment representing Route 1, returning
the segment from measures 5 through 10. This segment might represent a
construction zone. (This example uses the definitions from the example in
Section 7.7.)
SELECT SDO_LRS.DYNAMIC_SEGMENT(route_geometry, 5, 10)
FROM lrs_routes WHERE route_id = 1;
SDO_LRS.DYNAMIC_SEGMENT(ROUTE_GEOMETRY,5,10)(SDO_GTYPE, SDO_SRID, SDO_POINT(X, Y
