MultiPoint

Topic Status: Some information in this topic is preview and subject to change in future releases. Preview information describes new features or changes to existing features in Microsoft SQL Server 2016 Community Technology Preview 2 (CTP2).

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);

This 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.

SELECT @g.STGeometryN(1).STAsText();
