ST_GeomCollFromShape
Remarque :
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 1 MULTIPOINT ( 20 20, 30 30, 20 40, 30 50) 2 MULTILINESTRING (( 10.02000000 20.01000000, 10.32000000 23.98000000, 11.92000000 25.64000000),( 9.55000000 23.75000000, 15.36000000 30.11000000), ( 10 10, 20 20, 30 30, 40 40, 90 90)) 3 MULTIPOLYGON ((( 0 0, 4 0, 4 4, 0 4, 0 0)( 1 1, 1 2, 2 2, 2 1, 1 1)), (( -1 -1, -2 -1, -2 -2, -1 -2, -1 -1)) (3 rows)
