26.16 SDO_LRS.GEOM_SEGMENT_END_PT

Format

SDO_LRS.GEOM_SEGMENT_END_PT(
     geom_segment IN SDO_GEOMETRY 
     [, dim_array IN SDO_DIM_ARRAY] 
     ) RETURN SDO_GEOMETRY;

Description

Returns the end point of a geometric segment.

Parameters

geom_segment

Geometric segment (LRS segment) containing measure information.

dim_array

Dimensional information array corresponding to geom_segment, usually selected from one of the xxx_SDO_GEOM_METADATA views (described in Geometry Metadata Views).

Usage Notes

This function returns the end point of geom_segment.

An exception is raised if geom_segment has an invalid geometry type or dimensionality.

The _3D format of this function (SDO_LRS.GEOM_SEGMENT_END_PT_3D) is available. For information about _3D formats of LRS functions, see 3D Formats of LRS Functions.

Examples

The following example returns the end point of the geometric segment representing Route 1. (This example uses the definitions from the example in Example of LRS Functions.)

SELECT  SDO_LRS.GEOM_SEGMENT_END_PT(route_geometry)
  FROM lrs_routes WHERE route_id = 1;
