A MultiPoint is a collection of zero or more points. The boundary of a MultiPoint instance is empty.
The following example creates a geometry MultiPoint instance with SRID 23 and two points: one point with the coordinates (2, 3), one point with the coordinates (7, 8), and a Z value of 9.5.
DECLARE @g geometry;
SET @g = geometry::STGeomFromText('MULTIPOINT((2 3), (7 8 9.5))', 23); The following example expresses the MultiPoint instance using STMPointFromText().
DECLARE @g geometry;
SET @g = geometry::STMPointFromText('MULTIPOINT((2 3), (7 8 9.5))', 23); The following example uses the method STGeometryN() to retrieve a description of the first point in the collection.
SELECT @g.STGeometryN(1).STAsText();
