ST_MLineFromText

8.8.1. Well-Known Text (WKT)

Name

ST_MLineFromText — Return a specified ST_MultiLineString value from WKT representation.

Synopsis

+geometry +ST_MLineFromText(+`text `+WKT, integer srid`)`;

+geometry +ST_MLineFromText(+`text `+WKT`)`;

Description

Makes a Geometry from Well-Known-Text (WKT) with the given SRID. If SRID is not given, it defaults to 0.

OGC SPEC 3.2.6.2 - option SRID is from the conformance suite

Returns null if the WKT is not a MULTILINESTRING

If you are absolutely sure all your WKT geometries are points, don’t use this function. It is slower than ST_GeomFromText since it adds an additional validation step.
