Valeur de retour
Type : Microsoft.SqlServer.Types. . :: . .SqlGeometry
A SqlGeometry value that represents the convex hull of the calling SqlGeometry.
Notes
STConvexHull returns the smallest convex polygon that contains the given SqlGeometry instance. Points or co-linear LineString instances will produce an instance of the same type as that of the input.
