Spatial Function Reference •Functions that access qualitative or quantitative properties of a geometry •Functions that describe relations between two geometries •Functions that create new geometries from existing ones 2291 12.17.1 Spatial Function Reference For general background about MySQL support for using spatial data, see Section 11.4, “Spatial Data Types” . The following table lists each spatial function and provides a short description of each one. Table 12.21 Spatial Functions Name Description Introduced GeomCollection() Construct geometry collection from geometries GeometryCollection() Construct geometry collection from geometries LineString() Construct LineString from Point values MBRContains() Whether MBR of one geometry contains MBR of another MBRCoveredBy() Whether one MBR is covered by another MBRCovers() Whether one MBR covers another MBRDisjoint() Whether MBRs of two geometries are disjoint MBREquals() Whether MBRs of two geometries are equal MBRIntersects() Whether MBRs of two geometries intersect MBROverlaps() Whether MBRs of two geometries overlap MBRTouches() Whether MBRs of two geometries touch MBRWithin() Whether MBR of one geometry is within MBR of another MultiLineString() Contruct MultiLineString from LineString values MultiPoint() Construct MultiPoint from Point values MultiPolygon() Construct MultiPolygon from Polygon values Point() Construct Point from coordinates Polygon() Construct Polygon from LineString arguments
