  const countProp = node.property("count");
  const query = new Cypher.Merge(node)
      .onCreateSet([countProp, new Cypher.Literal(1)])
      .onMatchSet([countProp, Cypher.plus(countProp, new Cypher.Literal(1))]);
  

  MERGE (this0:MyLabel)

1.7.4

Patch Changes

• #245 a63337d Thanks @angrykoala! - Deprecate Merge.onCreate in favor of Merge.onCreateSet to better reflect the resulting Cypher ON CREATE SET

• #244 347ae01 Thanks @angrykoala! - Fix clauses order when using Merge.onCreate along with .set

  For example:

  const query = new Cypher.Merge(node)
      .onCreate([node.property("age"), new Cypher.Param(23)])
      .set([node.property("age"), new Cypher.Param(10)]);
  

  MERGE (this0:MyLabel)
  ON CREATE SET
      this0.age = $param1
  SET
      this0.age = $param0
  

1.7.3

Patch Changes

• #236 34552dc Thanks @angrykoala! - Support for chained .yield:

  const customProcedure = new Cypher.Procedure("customProcedure", []).yield("result1").yield(["result2", "aliased"]);
  

  is equivalent to:

  const customProcedure = new Cypher.Procedure("customProcedure", []).yield("result1", ["result2", "aliased"]);
  

  and results in the Cypher:

  CALL customProcedure() YIELD result1, result2 AS aliased
  

1.7.2

Patch Changes

• #230 f37cc99 Thanks @angrykoala! - Support for passing undefined to .where:

  const n = new Cypher.Node();
  new Cypher.Match(n).where(undefined).return(n);
  

  This will generate the following Cypher:

  MATCH(n)
  RETURN n
  

  Note that the WHERE clause is omitted if the predicate is undefined
