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);
MultiPoint instance can also be expressed using
STMPointFromText() as shown below.
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.
