`Count`

Cypher® COUNT subqueries can be created with new Cypher.Count(). To do this, a valid query needs to be passed to Count.

Note that count subqueries can also be used as predicates in WHERE clauses. For example:

const subquery = new Cypher.Match(new Cypher.Node({ labels: ["Movie"] })).return("*");

const countExpr = new Cypher.Count(subquery);
const match = new Cypher.Match(new Cypher.Node())
    .where(Cypher.gt(countExpr, new Cypher.Literal(10)))
    .return("*");

MATCH (this0)
WHERE COUNT {
    MATCH (this1:Movie)
    RETURN *
} > 10
RETURN *

Simple `Count` subqueries

Instead of a Clause, a Pattern can be passed directly to a Count subquery:

const countExpr = new Cypher.Count(new Cypher.Pattern(new Cypher.Node(), { labels: ["Movie"] }))

const match = new Cypher.Match(new Cypher.Node())
    .where(Cypher.gt(countExpr, new Cypher.Literal(10)))
    .return("*");

MATCH (this0)
WHERE COUNT {
    (this1:Movie)
} > 10
RETURN *
