Exists

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

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 existsExpression = new Cypher.Exists(subquery);
const match = new Cypher.Match(new Cypher.Node()).where(existsExpression).return("*");
MATCH (this0)
WHERE EXISTS {
    MATCH (this1:Movie)
    RETURN *
}
RETURN *
