We’re overhauling Dgraph’s docs to make them clearer and more approachable. If you notice any issues during this transition or have suggestions, please let us know.
Syntax Examples:
  • aliasName : predicate
  • aliasName : predicate { ... }
  • aliasName : varName as ...
  • aliasName : count(predicate)
  • aliasName : max(val(varName))
An alias provides an alternate name in results. Predicates, variables, and aggregates can be aliased by prefixing with the alias name and :. Aliases do not have to be different to the original predicate name, but, within a block, an alias must be distinct from predicate names and other aliases returned in the same block. Aliases can be used to return the same predicate multiple times within a block. Query Example: directors with name matching term Steven, their UID, English name, average number of actors per movie, total number of films, and the name of each film in English and French. 
{
  ID as var(func: allofterms(name@en, "Steven")) @filter(has(director.film)) {
    director.film {
      num_actors as count(starring)
      average as avg(val(num_actors))
    }
  }

films(func: uid(ID)) { director_id : uid english_name : name@en average_actors :
val(average) num_films : count(director.film)

    films : director.film {
      name : name@en
      english_name : name@en
      french_name : name@fr
    }
  }
}
