Definition

ST_IsMeasured takes an ST_Geometry as an input parameter and returns 1 if the given geometry has measures or 0 if it does not.

Syntax

Return type

Integer (Boolean)

Example

CREATE TABLE ism_test (id integer, geometry sde.st_geometry);

INSERT INTO ISM_TEST VALUES (
1902,
sde.st_geometry ('polygon ((40 120, 90 120, 90 150, 40 150, 40 120))', 0)
);

INSERT INTO ISM_TEST VALUES (
1903,
sde.st_geometry ('multipoint m(10 10 5, 50 10 6, 10 30 8)' , 0)
);

INSERT INTO ISM_TEST VALUES (
1904,
sde.st_geometry ('linestring z(10 10 166, 20 10 168)', 0)
);

INSERT INTO ISM_TEST VALUES (
1905, 
sde.st_geometry ('point zm(10 10 16 30)', 0)
);

SELECT id, sde.st_ismeasured (geometry) Has_Ms
FROM ISM_TEST;
