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;
