Dışbükey olan hull temsil eden bir nesnesi bir geometry Örnek.

.STConvexHull ( )

Dönüş Türleri

SQL Server döndürme türü: geometry

CLR dönüş türü: SqlGeometry

Remarks

STConvexHull() returns the smallest convex polygon that contains the given geometry instance.Points or co-linear LineString instances will produce an instance of the same type as that of the input.

Örnekler

The following example uses STConvexHull() to find the convex hull of a non-convex Polygongeometry instance.

DECLARE @g geometry;
SET @g = geometry::STGeomFromText('POLYGON((0 0, 0 2, 1 1, 2 2, 2 0, 0 0))', 0);
SELECT @g.STConvexHull().ToString();
