MultiPoint

Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance

A MultiPoint is a collection of zero or more points. The boundary of a MultiPoint instance is empty.

Examples

Example A.

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);  

Example B.

The following example expresses the MultiPoint instance using STMPointFromText().

DECLARE @g geometry;  
SET @g = geometry::STMPointFromText('MULTIPOINT((2 3), (7 8 9.5))', 23);  

Example C.

The following example uses the method STGeometryN() to retrieve a description of the first point in the collection.

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