To delete an edge, use the match clause to find your edges, then add the
variable to the DELETE.
```
SELECT *
FROM cypher('graph_name', $$
MATCH (n {name: 'Andres'})-[r:KNOWS]->()
DELETE r
$$) as (v agtype);
```
The above query will just delete the relationship or edge while the vertex
will remain there.
But we use the detach delete command to delete the edges first associated
with a vertex and then the vertex would be deleted.
```
SELECT *
FROM cypher('graph_name', $$
MATCH (v:Useless)
DETACH DELETE v
$$) as (v agtype);
```
So, there is no chance that vertex will be deleted directly by deleting the
edges because vertex cannot be deleted if it has vertices attached with it
using the delete command only.
