# Geometry Types

## Description

MariaDB provides a standard way of creating spatial columns for geometry types, for example, with [CREATE TABLE](../../sql-statements/data-definition/create/create-table) or [ALTER TABLE](../../sql-statements/data-definition/alter/alter-table). Spatial columns are supported for [MyISAM](../../../server-usage/storage-engines/myisam-storage-engine), [InnoDB](../../../server-usage/storage-engines/innodb) and [ARCHIVE](../../../server-usage/storage-engines/archive)\
tables. See also [SPATIAL INDEX](spatial-index).

The basic geometry type is `GEOMETRY`, but the type can be more specific. The following types are supported:

* [POINT](../../sql-statements/geometry-constructors/geometry-constructors/point)
* [LINESTRING](../../sql-statements/geometry-constructors/geometry-constructors/linestring)
* [POLYGON](../../sql-statements/geometry-constructors/geometry-constructors/polygon)
* [MULTIPOINT](../../sql-statements/geometry-constructors/geometry-constructors/multipoint)
* [MULTILINESTRING](../../sql-statements/geometry-constructors/geometry-constructors/multilinestring)
* [MULTIPOLYGON](../../sql-statements/geometry-constructors/geometry-constructors/multipolygon)
* [GEOMETRYCOLLECTION](../../sql-statements/geometry-constructors/geometry-constructors/geometrycollection)
* GEOMETRY

## Examples

**Note:** For clarity, only one type is listed per table in the examples below, but a table row can contain multiple types.

```sql
CREATE TABLE object (shapeA POLYGON, shapeB LINESTRING);
```

```sql
INSERT INTO geometry_example VALUES
  (Point(0, 0)),
  (ST_PolygonFromText('POLYGON((0 0, 0 1, 1 1, 1 0, 0 0))')),
  (ST_LineFromText('LINESTRING(0 0, 1 1, 2 2)')),
  (ST_MultiLineStringFromText(
    'MULTILINESTRING((0 1, 0 2, 0 3),
    (1 0, 2 0, 3 0))')),
  (ST_MultiPointFromText('MULTIPOINT(0 0, 1 1, 0 1, 1 0)')),
  (ST_MultiPolygonFromText(
    'MULTIPOLYGON(((0 40, 0 20, 6 30, 12 20, 12 40, 0 40),
    (15 40, 15 20, 25 20, 30 25, 30 35, 25 40, 15 40)))'));
```

```sql
SELECT ST_AsWKT(g) FROM geometry_example;

+-----------------------------------------------------------------------------------------------+
| ST_AsWKT(g)                                                                                   |
+-----------------------------------------------------------------------------------------------+
| POINT(0 0)                                                                                    |
| POLYGON((0 0,0 1,1 1,1 0,0 0))                                                                |
| LINESTRING(0 0,1 1,2 2)                                                                       |
| MULTILINESTRING((0 1,0 2,0 3),(1 0,2 0,3 0))                                                  |
| MULTIPOINT(0 0,1 1,0 1,1 0)                                                                   |
| MULTIPOLYGON(((0 40,0 20,6 30,12 20,12 40,0 40),(15 40,15 20,25 20,30 25,30 35,25 40,15 40))) |
