All nonempty geometries include at least one pair of (X,Y) coordinates. It is a noninstantiable class but has a number of properties, described in the following list, that are common to all geometry values created from any of the Geometry subclasses. Geometry Properties A geometry value has the following properties: Its ...
https://dev.mysql.com/doc/refman/8.0/en/gis-geometry-class-hierarchy.html
The instantiable subclasses of Geometry are restricted to zero-, one-, and two-dimensional geometric objects that exist in two-dimensional coordinate space. All instantiable geometry classes are defined so that valid instances of a geometry class ...
https://dev.mysql.com/doc/refman/8.0/en/geometry-well-formedness-validity.html
For geometry values, MySQL distinguishes between the concepts of syntactically well-formed and geometrically valid. Syntactic well-formedness is also checked for attempts to store geometries into tables. It is permitted to insert, select, and ...
https://dev.mysql.com/doc/refman/8.0/en/opengis-geometry-model.html
In this model, each geometric object has the following general properties: It is associated with a spatial reference system, which describes the coordinate space in which the object is defined. The set of geometry types proposed by OGC's SQL with ...

OpenGIS proposes a number of functions that can produce geometries. In addition, Section 14.16.7, “Geometry Property Functions”, discusses several functions that construct new geometries from existing ones. If any geometry argument has an SRID ...These functions support all argument type combinations except those that are inapplicable according to the Open Geospatial Consortium ...

The descriptions of the instantiable geometric classes given under Section 13.4.2, “The OpenGIS Geometry Model” include the specific conditions that cause class instances to be classified as not simple. For example: SET @g1 = ... The functions ...
https://dev.mysql.com/doc/refman/8.0/en/gis-format-conversion-functions.html
MySQL supports the functions listed in this section for converting geometry values from internal geometry format to WKT or WKB format, or for swapping the order of X and Y coordinates. There are also functions to convert a string from WKT or WKB ...

The following table lists each built-in (native) function and operator and provides a short description of each one. For a table listing functions that are loadable at runtime, see Section 14.2, “Loadable Function Reference”. ->> Return value ...
