Returns the area measurement of an ST_Polygon or ST_MultiPolygon. For ST_MultiPolygon, returns the sum of the area measurements of the component polygons.
Valid Data Types
ST_Polygon and ST_MultiPolygon
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.
Returns a FLOAT value.
