# ST_ShortestLine

Introduction: Returns the shortest LineString between two geometries. The line starts on geom1 and ends on geom2. If either geometry is empty, the function returns null.

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

Format: `ST_ShortestLine(geom1: Geometry, geom2: Geometry)`

Return type: `Geometry`

Since: `v1.9.0`

SQL Example:

![ST_ShortestLine Point to Point](../../../image/ST_ShortestLine/ST_ShortestLine_point_point.svg "ST_ShortestLine Point to Point")

```sql
SELECT ST_ShortestLine(
        ST_GeomFromText('POINT (0 0)'),
        ST_GeomFromText('POINT (3 4)')
)
```

Output:

```
LINESTRING (0 0, 3 4)
```

SQL Example:

![ST_ShortestLine Point to LineString](../../../image/ST_ShortestLine/ST_ShortestLine_point_linestring.svg "ST_ShortestLine Point to LineString")

```sql
SELECT ST_ShortestLine(
        ST_GeomFromText('POINT (0 1)'),
        ST_GeomFromText('LINESTRING (0 0, 1 0, 2 0, 3 0, 4 0, 5 0)')
)
```

Output:

```
LINESTRING (0 1, 0 0)
```
