# ST_ShortestLine
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.
## Signatures
```sql theme={"system"}
ST_ShortestLine(geom1: Geometry, geom2: Geometry)
```
## Parameters
The geometry where the shortest line starts.
The geometry where the shortest line ends.
## Return type
The shortest LineString connecting the two geometries.
## Example
```sql theme={"system"}
SELECT ST_ShortestLine(
ST_GeomFromText('POINT (0 0)'),
ST_GeomFromText('POINT (3 4)')
)
```
```
LINESTRING (0 0, 3 4)
```
Point to LineString:
```sql theme={"system"}
SELECT ST_ShortestLine(
ST_GeomFromText('POINT (0 1)'),
ST_GeomFromText('LINESTRING (0 0, 1 0, 2 0, 3 0, 4 0, 5 0)')
)
```
```
LINESTRING (0 1, 0 0)
```
