Example

The polygon_test table is created with the single polygon column.

The INSERT statement inserts a polygon into the polygon column using the ST_PolyFromText function.

Oracle

CREATE TABLE polygon_test (pl1 sde.st_geometry);

INSERT INTO polygon_test VALUES (
 sde.st_polyfromtext ('polygon ((10.01 20.03, 10.52 40.11, 30.29 41.56, 31.78 10.74, 10.01 20.03))', 4326)
);

SQLite

CREATE TABLE polygon_test (id integer);

SELECT AddGeometryColumn(
 NULL,
 'polygon_test',
 'pl1',
 4326,
 'polygon',
 'xy',
 'null'
);

INSERT INTO polygon_test VALUES (
 1,
 st_polyfromtext ('polygon ((10.01 20.03, 10.52 40.11, 30.29 41.56, 31.78 10.74, 10.01 20.03))', 4326)
