ST_LineFromWKB — Makes a LINESTRING
from WKB with the given SRID
geometry ST_LineFromWKB(
bytea WKB)
;
geometry ST_LineFromWKB(
bytea WKB, integer srid)
;
The ST_LineFromWKB
function, takes a well-known binary
representation of geometry and a Spatial Reference System ID (SRID
)
and creates an instance of the appropriate geometry type - in this case, a
LINESTRING
geometry. This function plays the role of the Geometry
Factory in SQL.
If an SRID is not specified, it defaults to -1. NULL
is
returned if the input bytea
does not represent a LINESTRING
.
