Continuing the discussion from [Delete - Mutations](http://discuss.hypermode.com/t/delete-mutations/9791):

There are a lot of posts about deleting. The ones that I found and read deal with deleting through GraphQL, or JSON syntax, or some other client. What I want to do is delete an edge with the RDF triple syntax. `S P O .`

```auto
{
  delete {
    <0x2> <friend> <0x3> .
  }
}

```

Is this correct to delete the edge `friend` between uid `0x2` and `0x3`? There is no mention in this docs page concerning edges between nodes without the wildcard, which I don’t want in this case. I want to preserve the other existing friends. Not sure if I need to use an uid function here instead:

```auto
<0x2> <friend> uid("0x3") .

```

Or just use the uid as a string? All the other `SPO` methods are for predicates and not edges.

```auto
<0x2> <friend> "0x3" .

```

This should be right.

This syntax doesn’t exist in RDF. This is an especial function in the Upsert Block.

>
> `<0x2> <friend> "0x3" .`

Also, this isn’t related to an edge. As this is a scalar value.

> `<0x2> <friend> <0x3> .`

That’s the right syntax. I thought that this would be obvious in the docs. I mention that in the video. Maybe we should improve this @damian, @acarey in the docs.

Thanks for the confirmation. The doc page linked does not contain any Node to Node examples other than the wild cards. I was afraid of sending the wrong mutation with a production database.
