ST_PointFromText

Signature

GEOMETRY ST_PointFromText(VARCHAR wkt);
GEOMETRY ST_PointFromText(VARCHAR wkt, INT srid);

Description

Converts the Well Known Text wkt into a Geometry, optionally with spatial reference id srid. Verifies that wkt does in fact specify a POINT.

Note: If wkt specifies a Geometry with z-coordinates, they will be conserved in reality but suppressed when visualizing the Geometry as WKT.

Examples

SELECT ST_PointFromText('POINT(25 89)');
-- Answer: POINT(25 89)

SELECT ST_PointFromText('POINT(44 31)', 101);
-- Answer: POINT(44 31)

SELECT ST_PointFromText('MULTIPOINT((2 3), (4 5))', 2154);
-- Answer: The provided WKT Geometry is not a POINT.
