apoc.any.isDeleted
Function

This function is not considered safe to run from multiple threads. It is therefore not supported by the parallel runtime. For more information, see the Cypher Manual → Parallel runtime.

Details
Syntax	`apoc.any.isDeleted(object)`
Description	Returns true if the given `NODE` or `RELATIONSHIP` no longer exists.
Arguments	Name	Type	Description
	`object`	`ANY`	The node or relationship to check the non-existence of.
Returns	`BOOLEAN`

Example

Given this dataset:

CREATE (:Person {name: 'Alice'})-[:KNOWS]->(:Person {name: 'Bob'})

The following query checks whether a node and relationship are deleted, both before and after a DETACH DELETE within the same transaction:

MATCH (a:Person {name: 'Alice'})-[r:KNOWS]->()
WITH
  a,
  r,
  apoc.any.isDeleted(a) AS beforeDeleteNode,
  apoc.any.isDeleted(r) AS beforeDeleteRel
DETACH DELETE a
RETURN
  beforeDeleteNode,
  beforeDeleteRel,
  apoc.any.isDeleted(a) AS afterDeleteNode,
  apoc.any.isDeleted(r) AS afterDeleteRel

Results
beforeDeleteNode	beforeDeleteRel	afterDeleteNode	afterDeleteRel
false	false	true	true

Before the delete, both the node and relationship still exist, so the function returns false. After DETACH DELETE a, both have been removed and the function returns true.
