ST_PointFromText

Note:

Used in Oracle and SQLite only; for PostgreSQL, use ST_Point.

Definition

ST_PointFromText takes a well-known text representation of type point and a spatial reference ID and returns a point.

Syntax

Oracle

sde.st_pointfromtext (wkt varchar2, srid integer)

SQLite

st_pointfromtext (wkt text, srid int32)

Return type

ST_Point

Example

The point_test table is created with the single ST_Point column pt1.

The ST_PointFromText function converts the point text coordinates to the point format before the INSERT statement inserts the point into the pt1 column.

Oracle

CREATE TABLE point_test (pt1 sde.st_geometry);

INSERT INTO POINT_TEST VALUES (
 sde.st_pointfromtext ('point (10.01 20.03)', 4326)
);

SQLite

CREATE TABLE pt_test (id integer);

SELECT AddGeometryColumn(
 NULL,
 'pt_test',
 'pt1',
 4326,
 'point',
 'xy',
 'null'
);

INSERT INTO pt_test VALUES (
 1,
 st_pointfromtext ('point (10.01 20.03)', 4326)
);
