Functions That Create Geometry Values from WKB Values 12.17.4 Functions That Create Geometry Values from WKB Values These functions take as arguments a  BLOB  containing a Well-Known Binary (WKB) representation and, optionally, a spatial reference system identifier (SRID). They return the corresponding geometry. For a description of WKB format, see Well-Known Binary (WKB) Format. Functions in this section detect arguments in either Cartesian or geographic spatial reference systems (SRSs), and return results appropriate to the SRS. ST_GeomFromWKB()  accepts a WKB value of any geometry type as its first argument. Other functions provide type-specific construction functions for construction of geometry values of each geometry type. Prior to MySQL 8.0, these functions also accepted geometry objects as returned by the functions in Section 12.17.5, “MySQL-Specific Functions That Create Geometry Values” . Geometry arguments are no longer permitted and produce an error. To migrate calls from using geometry arguments to using WKB arguments, follow these guidelines: Unless otherwise specified, functions in this section handle their geometry arguments as follows: If the  options  argument is  NULL , the return value is  NULL . If the  options  argument is invalid, an error occurs to indicate why. Ranges shown are in degrees. If an SRS uses another unit, the range uses the corresponding values in its unit. The exact range limits deviate slightly due to floating-point arithmetic. These functions are available for creating geometries from WKB values: 2298 Constructs a  GeometryCollection  value using its WKB representation and SRID. These functions handle their arguments as described in the introduction to this section. • ST_GeomCollFromWKB( wkb  [,  srid  [,  options ]]) ,  ST_GeometryCollectionFromWKB( wkb [,  srid  [,  options ]]) • If a latitude value is not in the range [ − 90, 90], an  ER_LATITUDE_OUT_OF_RANGE  error occurs. • If a longitude value is not in the range ( − 180, 180], an  ER_LONGITUDE_OUT_OF_RANGE  error occurs. •For geographic SRS geometry arguments, if any argument has a longitude or latitude that is out of range, an error occurs: •If an SRID argument refers to an undefined spatial reference system (SRS), an  ER_SRS_NOT_FOUND error occurs. •By default, geographic coordinates (latitude, longitude) are interpreted as in the order specified by the spatial reference system of geometry arguments. An optional  options  argument may be given to override the default axis order.  options  consists of a list of comma-separated  key = value . The only permitted  key  value is  axis-order , with permitted values of  lat-long ,  long-lat  and  srid- defined  (the default). •If the WKB or SRID argument is  NULL , the return value is  NULL . •Rewrite constructs such as  ST_GeomFromWKB(Point(0, 0), 4326)  as  ST_SRID(Point(0, 0), 4326)  or  ST_GeomFromWKB(ST_AsWKB(Point(0, 0)), 4326) . •Rewrite constructs such as  ST_GeomFromWKB(Point(0, 0))  as  Point(0, 0) .
