Definition
The ST_Polygon accessor function takes a well-known text (WKT) representation and a spatial reference ID (SRID) and generates an ST_Polygon.
Syntax
Oracle
sde.st_polygon (wkt clob, srid integer)
PostgreSQL
sde.st_polygon (wkt clob, srid integer) sde.st_polygon (esri_shape bytea, srid integer)
SQLite
st_polygon (wkt text, srid int32)
Return type
ST_Polygon
Example
The following CREATE TABLE statement creates the polygon_test tables, which have a single column, p1. Then the INSERT statement converts a ring (a polygon that is both closed and simple) into an ST_Polygon and inserts it into the p1 column using the ST_Polygon function.
Oracle
CREATE TABLE polygon_test (p1 sde.st_geometry);
INSERT INTO polygon_test VALUES (
sde.st_polygon ('polygon ((10.01 20.03, 20.94 21.34, 35.93 10.04, 10.01 20.03))', 4326)
);
PostgreSQL
CREATE TABLE polygon_test (p1 sde.st_geometry);
INSERT INTO polygon_test VALUES (
sde.st_polygon ('polygon ((10.01 20.03, 20.94 21.34, 35.93 10.04, 10.01 20.03))', 4326)
);
SQLite
CREATE TABLE poly_test (id integerp1 geometryblob);
SELECT AddGeometryColumn(
NULL,
'poly_test',
'p1',
4326,
'polygon',
'xy',
'null'
);
INSERT INTO poly_test VALUES (
1,
st_polygon ('polygon ((10.01 20.03, 20.94 21.34, 35.93 10.04, 10.01 20.03))', 4326)
);
