Multiple query - one for predicates and one for shema - in one block?

graphpivot · October 13, 2019, 7:26pm

Hi! In the documentation in noted, than one can put multiple queries in one block.
Can I put one normal (predicate) query and one for the schema in one block?

This did not worked on play.dgraph.io:

  schema
{
  predicate
  type
}
{
  query(func: has(name), first:10){
    name
  }
}

Cheers!

Nope.

if res.Query != nil {
	return res, item.Errorf("Schema block is not allowed with query block")
}

          		switch item.Typ {
          		case itemOpType:
          			if item.Val == "mutation" {
          				return res, item.Errorf("Mutation block no longer allowed.")
          			}
          			if item.Val == "schema" {
          				if res.Schema != nil {
          					return res, item.Errorf("Only one schema block allowed ")
          				}
          				if res.Query != nil {
          					return res, item.Errorf("Schema block is not allowed with query block")
          				}
          				if res.Schema, rerr = getSchema(it); rerr != nil {
          					return res, rerr
          				}
          			} else if item.Val == "fragment" {
          				// TODO(jchiu0): This is to be done in ParseSchema once it is ready.
          				fnode, rerr := getFragment(it)
          				if rerr != nil {
          					return res, rerr
          				}

Thank your for your answer.

Maybe it’s not a bad idea to put a note to the documentation here and here that this kind of combining schema and predicate queries is not possible.

Cheers!

I agree, please fill up an issue for docs in Dgraph’s repo.
