SDO_LRS.TRANSLATE_MEASURE
This function adds translate_m to the start and end measures of geom_segment.
For example, if geom_segment has a start measure of 50 and an end measure of
100, and if translate_m is 10, the returned geometric segment has a start measure
of 60 and an end measure of 110, as shown in Figure 16–1.
Figure 16–1 Translating a Geometric Segment
M = 50 M = 100 M = 60 M = 110
Translate (10)
An exception is raised if geom_segment has an invalid geometry type or
dimensionality.
The _3D format of this function (SDO_LRS.TRANSLATE_MEASURE_3D) is
available. For information about _3D formats of LRS functions, see Section 7.4.
The following example translates (shifts) by 10 the geometric segment representing
Route 1. (This example uses the definitions from the example in Section 7.7.)
SELECT SDO_LRS.TRANSLATE_MEASURE(a.route_geometry, m.diminfo, 10)
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;
