SDO_LRS.IS_MEASURE_INCREASING Format Description Parameters Usage Notes Examples SDO_LRS.IS_MEASURE_INCREASING( geom_segment IN SDO_GEOMETRY [, dim_array IN SDO_DIM_ARRAY] ) RETURN VARCHAR2; SDO_LRS.IS_MEASURE_INCREASING Checks if the measure values along an LRS segment are increasing (that is, ascending in numerical value). geom_segment Geometric segment to be checked. 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). This function returns TRUE if the measure values along an LRS segment are increasing and FALSE if the measure values along an LRS segment are not increasing. The start and end measures of geom_segment must be defined (cannot be null). The _3D format of this function (SDO_LRS.IS_MEASURE_INCREASING_3D) is available. For information about _3D formats of LRS functions, see Section 7.4. See also the SDO_LRS.IS_MEASURE_DECREASING function. The following example checks if the measure values along the geometric segment representing Route 1 are increasing. (This example uses the definitions from the example in Section 7.7.)
