STNumGeometries (geography Data Type)

[!INCLUDE SQL Server Azure SQL Database Azure SQL Managed Instance]

Returns the number of geometries that make up a geography instance.

Syntax

  
.STNumGeometries ( )  

[!INCLUDEsql-server-tsql-previous-offline-documentation]

Return Types

[!INCLUDEssNoVersion] return type: int

CLR return type: SqlInt32

Remarks

This method returns 1 if the geography instance is not a MultiPoint, MultiLineString, MultiPolygon, or GeometryCollection instance, or 0 if the geography instance is empty.

Examples

The following example creates a MultiPoint instance and uses STNumGeometries() to find out how many geometries the instance contains.

DECLARE @g geography;  
SET @g = geography::STGeomFromText('MULTIPOINT((-122.360 47.656), (-122.343 47.656))', 4326);  
SELECT @g.STNumGeometries();
