# ST_ForceCollection

Introduction: This function converts the input geometry into a GeometryCollection, regardless of the original geometry type. If the input is a multipart geometry, such as a MultiPolygon or MultiLineString, it will be decomposed into a GeometryCollection containing each individual Polygon or LineString element from the original multipart geometry.

![ST_ForceCollection](../../../image/ST_ForceCollection/ST_ForceCollection.svg "ST_ForceCollection")

Format: `ST_ForceCollection(geom: Geometry)`

Return type: `Geometry`

Since: `v1.6.1`

SQL Example

```sql
SELECT ST_ForceCollection(
            ST_GeomFromWKT(
                "MULTIPOINT (30 10, 40 40, 20 20, 10 30, 10 10, 20 50)"
    )
)
```

Output:

```
GEOMETRYCOLLECTION (POINT (30 10), POINT (40 40), POINT (20 20), POINT (10 30), POINT (10 10), POINT (20 50))
```
