      Value Query Expression

      The value query expression allows you to specify a scalar value derived from a nested query specification. The output of this expression is expected to be either a single value or null.

      <value query expression> ::= "VALUE" <nested query specification>
         
      <nested query specification> ::= "{" <query specification> "}"
      

      Details

      • The query specification must conclude with a result statement that adheres to the following requirements:
        • Must include a RETURN statement with a single return item, and must not contain a GROUP BY clause.
        • The return item in the RETURN statement must either utilize an aggregation function or explicitly include LIMIT 1. If neither is specified, LIMIT 1 will be implicitly applied to ensure only a single result is returned.

      Example Graph

      The following examples run against this graph:

      To create this graph, run the following query against an empty graph:

      INSERT (p1:Paper {_id:'P1', title:'Efficient Graph Search', score:6}),
             (p2:Paper {_id:'P2', title:'Optimizing Queries', score:9}),
             (p3:Paper {_id:'P3', title:'Path Patterns', score:7}),
             (p1)-[:Cites]->(p2),
             (p2)-[:Cites]->(p3)
      

      Examples

      LET avgScore = VALUE {MATCH (n) RETURN avg(n.score)}
      MATCH (n) WHERE n.score > avgScore
      RETURN n.title
      

      Result:

      n.title
