 === Query a composite database constituent using elementId
 
-The `graph.byElementId()` function (introduced in Neo4j 5.13), can be used in the `USE` clause to resolve a constituent graph to which a given element id belongs.
-In the below example, it is assumed that the DBMS contains a composite database constituent, which contains the element id `4:c0a65d96-4993-4b0c-b036-e7ebd9174905:0`.
-If the constituent database is not a standard database in the DBMS an error will be thrown:
+The xref:functions/graph.adoc#functions-graph-by-elementid[`graph.byElementId()`] function can be used in the `USE` clause to resolve a constituent graph to which a given xref:functions/scalar.adoc#functions-elementid[element id] belongs.
+As of Neo4j 5.26, it is supported on both standard and composite databases (on previous versions it is only available on composite databases).
+
+[NOTE]
+On a standard database, a `USE` clause with `graph.byElementId()` cannot be combined with other `USE` clauses unless the subsequent `USE` clauses reference the same element id.
+
+In the below example, it is assumed that the DBMS contains the database corresponding to the given element id. If you are connected to a composite database it needs to be a element id to a constituent database, which is a standard database in the DBMS.
