Descrizione

Makes a Geometry from 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 MULTIPOINT

	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.

Questo metodo implementa le OGC Simple Features Implementation Specification for SQL 1.1.

3.2.6.2

Questo metodo implementa la specifica SQL/MM.

SQL-MM 3: 9.2.4
