MySQL provides a standard way of creating spatial columns for
geometry types, for example, with CREATE
TABLE or ALTER TABLE.
Spatial columns are supported for
MyISAM,
InnoDB,
NDB, and
ARCHIVE tables. See also the
notes about spatial indexes under
Section 11.5.3.6, “Creating Spatial Indexes”.
Use the CREATE TABLE
statement to create a table with a spatial column:
CREATE TABLE geom (g GEOMETRY);
Use the ALTER TABLE
statement to add or drop a spatial column to or from an
existing table:
ALTER TABLE geom ADD pt POINT; ALTER TABLE geom DROP pt;
