12.16.4 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.

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.

These functions also accept geometry objects as returned by the functions in Section 12.16.5, “MySQL-Specific Functions That Create Geometry Values”. Thus, those functions may be used to provide the first argument to the functions in this section. However, as of MySQL 5.7.19, use of geometry arguments is deprecated and generates a warning. Geometry arguments are not accepted in MySQL 8.0. To migrate calls from using geometry arguments to using WKB arguments, follow these guidelines:

For a description of WKB format, see Well-Known Binary (WKB) Format.

Rewrite constructs such as ST_GeomFromWKB(Point(0, 0)) as Point(0, 0).
Rewrite constructs such as ST_GeomFromWKB(Point(0, 0), 4326) as ST_GeomFromWKB(ST_AsWKB(Point(0, 0)), 4326). (Alternatively, in MySQL 8.0, you can use ST_SRID(Point(0, 0), 4326).)
