real geometries available in modern MySQL versions. However, the spatial
functions are not as rich as other backends like PostGIS.
.. warning::
True spatial indexes (R-trees) are only supported with
MyISAM tables on MySQL. [#fnmysqlidx]_ In other words, when using
MySQL spatial extensions you have to choose between fast spatial
lookups and the integrity of your data -- MyISAM tables do
not support transactions or foreign key constraints.

For MyISAM tables, ``SPATIAL INDEX`` creates an R-tree index. For storage
engines that support nonspatial indexing of spatial columns, the engine
creates a B-tree index. A B-tree index on spatial values will be useful
for exact-value lookups, but not for range scans.

Spatial database

PostgreSQL (with PostGIS), MySQL (mostly with MyISAM engine), Oracle, and SQLite
(with SpatiaLite) are the spatial databases currently supported.
