MySQL provides a standard way of creating spatial columns for
geometry types, for example, with CREATE
TABLE
or ALTER TABLE
.
Currently, spatial columns are supported for
MyISAM
, InnoDB
,
NDB
, and ARCHIVE
tables. See also the annotations about spatial indexes under
Section 11.17.6.1, “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;
