ST_GeomCollFromShape

Note:

ST_Geometry in PostgreSQL only

Definition

ST_GeomCollFromShape constructs a geometry collection from an ESRI shape.

Syntax

sde.st_geomcollfromshape (esri_shape bytea, srid integer)

Return type

ST_GeomCollection

Example

Create a table, gcollection.

CREATE TABLE gcollection (pkey integer, shape sde.st_geomcollection );

Insert values in the gcollection table.

INSERT INTO gcollection VALUES
(1,
sde.st_geomcollfromshape (sde.st_asshape(sde.st_geomcollection
('multipoint(20 20, 30 30, 20 40,30 50)', 0))::bytea, 0));

INSERT INTO gcollection VALUES 
(2,
sde.st_geomcollfromshape (sde.st_asshape(sde.st_geomcollection
('multilinestring ((10.02 20.01, 10.32 23.98, 11.92 25.64),
(9.55 23.75, 15.36 30.11), (10 10, 20 20, 30 30, 40 40, 90 90))', 0))::bytea, 0));

INSERT INTO gcollection VALUES 
(3,
sde.st_geomcollfromshape (sde.st_asshape(sde.st_geomcollection
('multipolygon(((0 0, 4 0, 4 4, 0 4, 0 0),(1 1, 2 1, 2 2, 1 2, 1 1)), 
((-1 -1, -1 -2, -2 -2, -2 -1, -1 -1)))', 0))::bytea, 0));

Select the geometry from the gcollection table.

SELECT pkey, sde.st_astext(shape) 
FROM gcollection;

 pkey   st_astext
