Returns the convex hull of the ST_Geometry value.

Valid Data Types

All ST_Geometry types.

This method can be called on 3D geometries (those that include z coordinates). However, the z coordinate is ignored in method calculations. Consequently, any z coordinates returned by this method should be ignored. Teradata recommends using the Make_2D method to strip out the z coordinates of the return value.

Result Type

Returns an ST_Geometry value.
