ST_Geometry constructs a geometry from a well-known text representation.

Create a table, geoms, and insert values into it.

CREATE TABLE geoms (id integer, geometry sde.st_geometry);
INSERT INTO geoms (id, geometry) VALUES (

INSERT INTO geoms (id, geometry) VALUES (
1903,
sde.st_geometry ('polygon ((3 3, 4 6, 5 3, 3 3))', 0)
