# ST_Split

Split an input geometry by another geometry (called the blade).
Linear (LineString or MultiLineString) geometry can be split by a Point, MultiPoint, LineString, MultiLineString, Polygon, or MultiPolygon.
Polygonal (Polygon or MultiPolygon) geometry can be split by a LineString, MultiLineString, Polygon, or MultiPolygon.
In either case, when a polygonal blade is used then the boundary of the blade is what is actually split by.
ST\_Split will always return either a MultiLineString or MultiPolygon even if they only contain a single geometry.
Homogeneous GeometryCollections are treated as a multi-geometry of the type it contains.
For example, if a GeometryCollection of only Point geometries is passed as a blade it is the same as passing a MultiPoint of the same geometries.

## Return type

<ResponseField type="Geometry">
  The resulting geometry.
</ResponseField>

## Example

```sql theme={"system"}
SELECT ST_Split(
    ST_GeomFromWKT('LINESTRING (0 0, 1.5 1.5, 2 2)'),
    ST_GeomFromWKT('MULTIPOINT (0.5 0.5, 1 1)'))
```

```
MULTILINESTRING ((0 0, 0.5 0.5), (0.5 0.5, 1 1), (1 1, 1.5 1.5, 2 2))
```
