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

Returns a geometrycollection instance from an Open Geospatial Consortium (OGC) Well-Known Binary (WKB) representation.

Syntax

  
STGeomCollFromWKB ( 'WKB_geometrycollection' , SRID )  

Arguments

WKB_geometrycollection
Is the WKB representation of the geometrycollection instance you wish to return. WKB_geometrycollection is a varbinary(max) expression.

SRID
Is an int expression representing the spatial reference ID (SRID) of the geometry instance you wish to return.

Return Types

SQL Server return type: geometry

CLR return type: SqlGeometry

Remarks

The OGC type of the geometry instance returned by STGeomCollFromWKB() is set to GeomCollection, MultiPolygon, MultiLineString, or MultiPoint, depending on the corresponding WKB input.

This method will throw a FormatException exception if the input isn't well formatted.

Examples

The following example uses STGeomCollFromWKB() to create a geometry instance.

DECLARE @g geometry;  
SET @g = geometry::STGeomCollFromWKB(0x0107000000020000000103000000010000000400000000000000000014400000000000001440000000000000244000000000000014400000000000002440000000000000244000000000000014400000000000001440010100000000000000000024400000000000002440, 0);  
SELECT @g.STAsText();
