반환 값

유형: System.Data.SqlTypes.SqlDouble
A SqlDouble value specifying the total surface area. STArea will return 0 if a SqlGeography instance contains only 0- and 1-dimensional figures, or if it is empty.


Results for STArea are returned in the square of the unit of measure used by the spatial reference identifier of the geography instance; for example, if the SRID of the instance is 4326, STArea returns results in square meters.
