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
, BDB
, and
ARCHIVE
tables. (Support for storage engines
other than MyISAM
was added in MySQL 5.0.16.)
See also the annotations about spatial indexes under
Section 11.12.6.1, “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;
