https://dev.mysql.com/doc/refman/8.0/en/gis-geometry-class-hierarchy.html
The geometry classes define a hierarchy as follows: Geometry (noninstantiable) Point (instantiable) Curve (noninstantiable) LineString (instantiable) Line LinearRing Surface (noninstantiable) Polygon (instantiable) GeometryCollection (instantiable) ...All classes have properties, and instantiable classes may also have assertions (rules that define valid class ...

https://dev.mysql.com/doc/refman/8.0/en/gis-class-geometry.html
Geometry values of types (LineString, MultiPoint, MultiLineString) are either simple or nonsimple. The dimensions of MultiPoint, MultiLineString, and MultiPolygon objects are the same as the dimensions of the elements they consist of. It is a ...
https://dev.mysql.com/doc/refman/8.0/en/information-schema-st-geometry-columns-table.html
Permitted values are: geometry, point, linestring, polygon, multipoint, multilinestring, multipolygon, geometrycollection. The ST_GEOMETRY_COLUMNS table provides information about table columns that store spatial data. This table is based on the ...
https://dev.mysql.com/doc/refman/8.0/en/keywords.html
Certain keywords, such as SELECT, DELETE, or BIGINT, are reserved and require special treatment for use as identifiers such as table and column names. This may also be true for the names of built-in functions. Some keywords which are otherwise ...
https://dev.mysql.com/doc/refman/8.0/en/gis-wkb-functions.html
ST_MPointFromWKB(wkb [, srid [, options]]), ST_MultiPointFromWKB(wkb [, srid [, options]]) Constructs a MultiPoint value using its WKB representation and SRID. These functions take as arguments a BLOB containing a Well-Known Binary (WKB) ...
https://dev.mysql.com/doc/refman/8.0/en/gis-polygon-property-functions.html
Such components are extracted and made into a single MultiPolygon, MultiLineString, or MultiPoint for centroid computation. Functions in this section return properties of Polygon or MultiPolygon values. Unless otherwise specified, functions in this ...
https://dev.mysql.com/doc/refman/8.0/en/gis-class-geometrycollection.html
Restrictions may be based on: Element type (for example, a MultiPoint may contain only Point elements) Dimension Constraints on the degree of spatial overlap between elements . A GeomCollection is a geometry that is a collection of zero or more ...
