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)
);
