[NOTE]
====
On a <<composite-databases, composite database>>, the `id()` function should be used with caution.
It is recommended to use <<functions-elementid, `elementId()`>> instead.

When called in database-specific subqueries, the resulting id value for a node or relationship is local to that database.
The local id for nodes or relationships from different databases may be the same.

When called from the root context of a query, the resulting value is an extended id for the node or relationship.
The extended id is likely different from the local id for the same node or relationship.
