MySQL-Specific Functions That Create Geometry Values INSERT INTO t1 (pt_col) VALUES(Point(1,2)); • GeomCollection( g  [,  g ] ...) • GeometryCollection( g  [,  g ] ...) • LineString( pt  [,  pt ] ...) • MultiLineString( ls  [,  ls ] ...) • MultiPoint( pt  [,  pt2 ] ...) • MultiPolygon( poly  [,  poly ] ...) • Point( x ,  y ) • Polygon( ls  [,  ls ] ...) Constructs a  GeomCollection  value from the geometry arguments. GeomCollection()  returns all the proper geometries contained in the arguments even if a nonsupported geometry is present. GeomCollection()  with no arguments is permitted as a way to create an empty geometry. Also, functions such as  ST_GeomFromText()  that accept WKT geometry collection arguments understand both OpenGIS  ’GEOMETRYCOLLECTION EMPTY’  standard syntax and MySQL ’GEOMETRYCOLLECTION()’  nonstandard syntax. GeomCollection()  and  GeometryCollection()  are synonymous, with  GeomCollection()  the preferred function. Constructs a  GeomCollection  value from the geometry arguments. GeometryCollection()  returns all the proper geometries contained in the arguments even if a nonsupported geometry is present. GeometryCollection()  with no arguments is permitted as a way to create an empty geometry. Also, functions such as  ST_GeomFromText()  that accept WKT geometry collection arguments understand both OpenGIS  ’GEOMETRYCOLLECTION EMPTY’  standard syntax and MySQL ’GEOMETRYCOLLECTION()’  nonstandard syntax. GeomCollection()  and  GeometryCollection()  are synonymous, with  GeomCollection()  the preferred function. Constructs a  LineString  value from a number of  Point  or WKB  Point  arguments. If the number of arguments is less than two, the return value is  NULL . Constructs a  MultiLineString  value using  LineString  or WKB  LineString  arguments. Constructs a  MultiPoint  value using  Point  or WKB  Point  arguments. Constructs a  MultiPolygon  value from a set of  Polygon  or WKB  Polygon  arguments. Constructs a  Point  using its coordinates. Constructs a  Polygon  value from a number of  LineString  or WKB  LineString  arguments. If any argument does not represent a  LinearRing  (that is, not a closed and simple  LineString ), the return value is  NULL . 2300
