ST_Geometry

Definition

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

When creating spatial tables that will be used with ArcGIS, it is best to create the column as the geometry supertype (for example, ST_Geometry) rather than specifying an ST_Geometry subtype, such as ST_LineString.

Syntax

Oracle

  • For linestrings, polygons, and points

    sde.st_geometry (wkt clob, srid integer)

  • For optimized points (which do not launch an extproc agent and, therefore, process the query more rapidly)

    sde.st_geometry (x, y, z, m, srid)

    Use optimized point construction when performing batch inserts of large numbers of point data.

  • For parametric circles

    sde.st_geometry (x, y, z, m, radius, number_of_points, srid)

  • For parametric ellipses

    sde.st_geometry (x, y, z, m, semi_major_axis, semi_minor_axis, angle, number_of_points, srid)

  • For parametric wedges

    sde.st_geometry (x, y, z, m, startangle, endangle, outerradius, innerradius, number_of_points, srid)

PostgreSQL

  • For linestrings, polygons, and points

    sde.st_geometry (wkt, srid integer)
    sde.st_geometry (esri_shape bytea, srid integer)

  • For parametric circles

    sde.st_geometry (x, y, z, m, radius, number_of_points, srid)

  • For parametric ellipses

    sde.st_geometry (x, y, z, m, semi_major_axis, semi_minor_axis, angle, number_of_points, srid)

  • For parametric wedges

    sde.st_geometry (x, y, z, m, startangle, endangle, outerradius, innerradius, number_of_points, srid)

SQLite

  • For linestrings, polygons, and points

    st_geometry (text  WKT_string,int32 srid)

  • For parametric circles

    st_geometry (x, y, z, m, radius, number_of_points, srid)

  • For parametric ellipses

    st_geometry (x, y, z, m, semi_major_axis, semi_minor_axis, angle_of_rotation, number_of_points, srid)

  • For parametric wedges

    st_geometry (x, y, z, m, start_angle, end_angle, outer_radius, inner_radius, number_of_points, srid)

Examples

Creating and querying point, linestring, and polygon features

These examples create a table (geoms) and insert point, linestring, and polygon values into it.

Oracle

CREATE TABLE geoms (
 id integer,
 geometry sde.st_geometry
);
INSERT INTO GEOMS (id, geometry) VALUES (
 1901,
 sde.st_geometry ('point (1 2)', 4326)
);

--To insert the same point using optimized point construction:
INSERT INTO GEOMS (id, geometry) VALUES (
 1901,
 sde.st_geometry (1,2,null,null,4326)
);

INSERT INTO GEOMS (id, geometry) VALUES (
 1902,
 sde.st_geometry ('linestring (33 2, 34 3, 35 6)', 4326)
);

INSERT INTO GEOMS (id, geometry) VALUES (
 1903,
 sde.st_geometry ('polygon ((3 3, 4 6, 5 3, 3 3))', 4326)
);

PostgreSQL

CREATE TABLE geoms (
 id serial,
 geometry sde.st_geometry
);
INSERT INTO geoms (geometry) VALUES (
 sde.st_geometry ('point (1 2)', 4326)
);

INSERT INTO geoms (geometry) VALUES (
 sde.st_geometry ('linestring (33 2, 34 3, 35 6)', 4326)
);

INSERT INTO geoms (geometry) VALUES (
 sde.st_geometry ('polygon ((3 3, 4 6, 5 3, 3 3))', 4326)
);

SQLite

CREATE TABLE geoms (
 id integer primary key autoincrement not null
);

SELECT AddGeometryColumn (
 NULL,
 'geoms',
 'geometry',
 4326,
 'geometry',
 'xy',
 'null'
);
INSERT INTO geoms (geometry) VALUES (
 st_geometry ('point (1 2)', 4326)
);

INSERT INTO geoms (geometry) VALUES (
 st_geometry ('linestring (33 2, 34 3, 35 6)', 4326)
);

INSERT INTO geoms (geometry) VALUES (
 st_geometry ('polygon ((3 3, 4 6, 5 3, 3 3))', 4326)
);

Creating and querying parametric circles

Create a table, radii, and insert circles into it.

Oracle

CREATE TABLE radii (
 id integer,
 geometry sde.st_geometry
);
INSERT INTO RADII (id, geometry) VALUES (
 1904,
 sde.st_geometry (10,10,NULL,NULL,25,50,4326)
