I have trouble when I try to delete a node using delete{ S \* \* .}

```auto
{
	delete { 
                <0x6> * * .
        }
}

```

When I run the commond above in Ratel, it returns “Message:Done”  
But I can still get all property the node using this uid.

and here’s my dgraph.type of \<0x6\>

```auto
type <人>{
    <ex_id>: String
    <身份证号>: String
    <ex_id>: String
    <性别>: String
    <地址>: String
     .....
     .....

```

The sample has the  
`_:node <dgraph.type> "人" . ` ?

I checked the schema and data Type, problem solved, thank you again!  
but if the node have many predicates, do I have to define all of the predicates in its Type so I can delete or expand the node ?  
What should I do if I dont know what kind of predicate a node would have ?  
And how can I get all the edge or predicate a node was connected if I don’t have the TYPE?

yep

Well, whoever is responsible for database administration has to define these things.

There’s a new feature now, which I’m not sure could be useful. That is “`expand(myDefinedType)`”. Maybe it could be used to a sort of debug the node and know which type it belongs to. But I don’t know yet if it would be useful for that.

As I said, Admin needs to define Types. You can find out what types there are by going to the “Schema” panel in Ratel UI. And every mutation you make must contain \<dgraph.type\>. Otherwise, it won’t work.

Also, if you need a “quick migration”. You can use the Upsert Block.

```auto
upsert {
  query {
    v as var(func: has(username)) #Make sure this predicate is used only by "Persons"
  }

  mutation {
  # Adding the dgraph.type based in the given Predicate.
    set {
       uid(v) <dgraph.type> "Person" .
    }

  }
}

```

You can also do combinations in the query to do precise upserts.

Cheers.

[According to the tour](https://dgraph.io/tour/schema/8/), you should be able to delete all triples for a node with something like this:

```auto
delete {
  <0x123> * * .
}

```

Is this something that was changed in more recent versions of Dgraph? I’m on v20.03.1.

For what it’s worth the node I’m trying to remove doesn’t have a type (it’s just a basic list with no index, e.g. `xyz [uid] .`) I can successfully delete nodes if I specify the predicate (`<0x123> <xyz> * .`).

No, you can combine bulk delete with “bulk migration” in upsert block.

I may need to open a different topic for this as it is distinct from the case here (where there was a type). I was basing my question on the title more than the context.
