ST_LineFromText — Makes a Geometry from WKT representation with the given SRID. If SRID is not given, it defaults to -1.
geometry ST_LineFromText(
text WKT)
;
geometry ST_LineFromText(
text WKT, integer srid)
;
Makes a Geometry from WKT with the given SRID. If SRID is not give, it defaults to -1. If WKT passed in is not a LINESTRING, then null is returned.
OGC SPEC 3.2.6.2 - option SRID is from the conformance suite. |
If you know all your geometries are LINESTRINGS, its more efficient to just use ST_GeomFromText. This just calls ST_GeomFromText and adds additional validation that it returns a linestring. |
