ST_LineFromWKB

Signatures

GEOMETRY ST_LineFromWKB(binary wkb);
GEOMETRY ST_LineFromWKB(binary wkb, INT srid);

Description

Converts the Well Known Binary wkb into a Geometry, optionally with spatial reference id srid. Verifies that wkb does in fact specify a LINESTRING.

Note

Implements the OpenGIS Simple Features Implementation Specification for SQL version 1.2.1

Examples
