ST_GeomFromShape
Remarque :
ST_Geometry in PostgreSQL only
Definition
ST_GeomFromShape constructs an ST_Geometry object from an ESRI shape.
Syntax
st_geomfromshape (esri_shape bytea, srid integer)
Return type
ST_Geometry
Example
The following example inserts a record into the geoshape table with an ID and two geometry columns.
CREATE TABLE geoshape (id integer, g1 sde.st_geometry, g2 bytea);
The INSERT statements insert the data into the columns of the geoshape table. The SELECT statement at the end ensures data was inserted into the g1 column.
INSERT INTO geoshape (id, g1) VALUES ( 1, sde.st_geometry ('point (10 10)', 0) ); INSERT INTO geoshape (id, g1) VALUES ( 2, sde.st_geometry ('linestring (10 10, 20 20, 30 30)', 0) ); UPDATE geoshape SET g2 = sde.st_asshape (g1) WHERE id = 1; UPDATE geoshape SET g2 = sde.st_asshape (g1) WHERE id = 2; SELECT id, sde.st_astext (sde.st_geomfromshape (g2, 0)) FROM geoshape; id st_astext 1 POINT ( 10 10) 2 LINESTRING ( 10 10, 20. 20, 3 30)
