## Signatures

```sql theme={"system"}
ST_GeneratePoints(geom: Geometry, numPoints: Integer, seed: Long = 0)
```

```sql theme={"system"}
ST_GeneratePoints(geom: Geometry, numPoints: Integer)
```

## Parameters

<ParamField body="geom" type="Geometry" required>
  The input geometry.
</ParamField>

<ParamField body="numPoints" type="Integer" required>
  The number of points.
</ParamField>

<ParamField body="seed" type="Long" default="0">
  The seed value.
</ParamField>

## Return type

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

## Example

```sql theme={"system"}
SELECT ST_GeneratePoints(
        ST_GeomFromWKT('POLYGON((0 0, 1 0, 1 1, 0 1, 0 0))'), 4
)
```

<Note>
  Due to the pseudo-random nature of point generation, the output of this function will vary between executions and may not match any provided examples.
