MultiPoint(pt1,pt2,...)

Description

Examples

SET @g = ST_GEOMFROMTEXT('MultiPoint( 1 1, 2 2, 5 3, 7 2, 9 3, 8 4, 6 6, 6 9, 4 9, 1 5 )');

CREATE TABLE gis_multi_point (g MULTIPOINT);
INSERT INTO gis_multi_point VALUES
    (MultiPointFromText('MULTIPOINT(0 0,10 10,10 20,20 20)')),
    (MPointFromText('MULTIPOINT(1 1,11 11,11 21,21 21)')),
    (MPointFromWKB(AsWKB(MultiPoint(Point(3, 6), Point(4, 10)))));

MultiPoint_Example:

CREATE TABLE multipoint_example (
  m MULTIPOINT
);
INSERT INTO multipoint_example VALUES
  (ST_MultiPointFromText('MULTIPOINT(0 0, 1 0, 1 1, 0 1)')),
  (ST_MPointFromText('MULTIPOINT(1 1, 2 2, 3 3, 4 4)')),
  (MultiPoint(Point(0, 0), Point(1, 1)));
INSERT INTO multipoint_example VALUES
  (MultiPointFromText('MULTIPOINT(0 0, 1 0, 1 1, 0 1)')),
  (MPointFromText('MULTIPOINT(1 1, 2 2, 3 3, 4 4)')),
  (MultiPoint(Point(0, 0), Point(1, 1)));
SELECT ST_AsWKT(m) FROM multipoint_example;
