STPolyFromWKB (geometry Data Type)
Returns a geometryPolygon instance from an Open Geospatial Consortium (OGC) Well-Known Binary (WKB) representation.
Syntax
STPolyFromWKB ( 'WKB_polygon' , SRID)
Arguments
WKB_polygon
Is the WKB representation of the geometryPolygon instance you wish to return. WKB_polygon is a varbinary(max) expression.SRID
Is an int expression representing the spatial reference ID (SRID) of the geometryPolygon instance you wish to return.
Return Types
SQL Server return type: geometry
CLR return type: SqlGeometry
OGC type: Polygon
Remarks
This method will throw a FormatException if the input is not well-formatted.
Examples
The following example uses STPolyFromWKB() to create a geometry instance.
DECLARE @g geometry;
SET @g = geometry::STPolyFromWKB(0x0103000000010000000400000000000000000014400000000000001440000000000000244000000000000014400000000000002440000000000000244000000000000014400000000000001440, 0);
SELECT @g.STAsText();
