Node Querying

Table 1. Functions
Qualified Name	Type
apoc.nodes.isDense `apoc.nodes.isDense(node NODE)` - returns true if the given `NODE` is a dense node.	`Function`
apoc.nodes.connected `apoc.nodes.connected(startNode NODE, endNode NODE, types STRING)` - returns true when a given `NODE` is directly connected to another given `NODE`. This function is optimized for dense nodes.	`Function`
apoc.node.relationship.exists `apoc.node.relationship.exists(node NODE, relTypes STRING)` - returns a `BOOLEAN` based on whether the given `NODE` has a connecting `RELATIONSHIP` (or whether the given `NODE` has a connecting `RELATIONSHIP` of the given type and direction).	`Function`
apoc.node.relationships.exist `apoc.node.relationships.exist(node NODE, relTypes STRING)` - returns a `BOOLEAN` based on whether the given `NODE` has connecting `RELATIONSHIP` values (or whether the given `NODE` has connecting `RELATIONSHIP` values of the given type and direction).	`Function`
apoc.nodes.relationships.exist `apoc.nodes.relationships.exist(nodes ANY, types STRING)` - returns a `BOOLEAN` based on whether or not the given `NODE` values have the given `RELATIONSHIP` values.	`Function`
apoc.node.relationship.types `apoc.node.relationship.types(node NODE, relTypes STRING)` - returns a `LIST<STRING>` of distinct `RELATIONSHIP` types for the given `NODE`.	`Function`
apoc.nodes.relationship.types `apoc.nodes.relationship.types(nodes ANY, types STRING)` - returns a `LIST<STRING>` of distinct `RELATIONSHIP` types from the given `LIST<NODE>` values.	`Function`
apoc.node.degree `apoc.node.degree(node NODE, relTypes STRING)` - returns the total degrees of the given `NODE`.	`Function Deprecated in Cypher 25`
apoc.node.id `apoc.node.id(node NODE)` - returns the id for the given virtual `NODE`.	`Function Deprecated in Cypher 25`
apoc.node.degree.in `apoc.node.degree.in(node NODE, relTypes STRING)` - returns the total number of incoming `RELATIONSHIP` values connected to the given `NODE`.	`Function Deprecated in Cypher 25`
apoc.node.degree.out `apoc.node.degree.out(node NODE, relTypes STRING)` - returns the total number of outgoing `RELATIONSHIP` values from the given `NODE`.	`Function`
apoc.node.labels `apoc.node.labels(node NODE)` - returns the labels for the given virtual `NODE`.	`Function`
apoc.any.properties `apoc.any.properties(object ANY, keys LIST<STRING>)` - returns all properties of the given object. The object can be a virtual `NODE`, a real `NODE`, a virtual `RELATIONSHIP`, a real `RELATIONSHIP`, or a `MAP`.	`Function`
apoc.any.property `apoc.any.property(object ANY, key STRING)` - returns the property for the given key from an object. The object can be a virtual `NODE`, a real `NODE`, a virtual `RELATIONSHIP`, a real `RELATIONSHIP`, or a `MAP`.	`Function`
apoc.label.exists `apoc.label.exists(node ANY, label STRING)` - returns true or false depending on whether or not the given label exists.	`Function`

Rel-direction-pattern Syntax:

[<]RELATIONSHIP_TYPE1[>]|[<]RELATIONSHIP_TYPE2[>]|…

Example: 'FRIEND|MENTORS>|<REPORTS_TO' will match to :FRIEND relationships in either direction, outgoing :MENTORS relationships, and incoming :REPORTS_TO relationships.

Table 2. Procedures
Qualified Name	Type
apoc.nodes.get `apoc.nodes.get(nodes ANY)` - returns all `NODE` values with the given ids.	`Procedure`
