Count

In this section we'll learn how to count results

By definition:

• The form count(predicate) counts how many predicate edges lead out of a node.
• The form count(uid) counts the number of UIDs matched in the enclosing block.

Counting with dqlx

To count predicates we use the Count function within the Select statement.
We then pass as the argument the predicate we want to count

dqlx

db.QueryType("Actor").Select(

"uid",

"name",

dqlx.Count("films")

)

dql

{

rootQuery(func: type(Animal)) {

uid

name

count(films)

}

}

Alias

Use the Alias function to alias the count attribute

dqlx

db.QueryType("Actor").Select(

"uid",

"name",

dql.Alias("count", dqlx.Count("films"))

)

dql

{

rootQuery(func: type(Animal)) {

uid

name

count: count(films)

}

}
