GEOMETRYCOLLECTION
(MULTIPOINT, MULTILINESTRING, MULTIPOLYGON, and GEOMETRYCOLLECTION) restrict collection
members to those having a particular geometry type.
12.16.4.2. Creating Spatial Values
This section describes how to create spatial values using Well-Known Text and Well-Known Binary
functions that are defined in the OpenGIS standard, and using MySQL-specific functions.
12.16.4.2.1. Creating Geometry Values Using WKT Functions
MySQL provides a number of functions that take as arguments a Well-Known Text representation and,
optionally, a spatial reference system identifier (SRID). They return the corresponding geometry.
GeomFromText()
implementation also provides type-specific construction functions for construction of geometry values of
each geometry type.
