示例

Oracle

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

INSERT INTO MPOINT_TEST VALUES (
1110,
sde.st_multipoint ('multipoint (1 2, 3 4, 5 6)', 0)
);

SELECT id, sde.st_astext (geometry) MULTIPOINT
FROM MPOINT_TEST
WHERE id = 1110; 

    ID      MULTIPOINT

  1110      MULTIPOINT  (1.00000000 2.00000000, 3.00000000 4.00000000,   
              5.00000000 6.0000000)

PostgreSQL

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

INSERT INTO mpoint_test VALUES (
1110,
sde.st_multipoint ('multipoint (1 2, 3 4, 5 6)', 0)
);

SELECT id, sde.st_astext (geometry) 
AS MULTIPOINT
FROM mpoint_test
WHERE id = 1110; 

    id      multipoint

  1110      MULTIPOINT  (1 2, 3 4, 5 6)
