CALL and procedures

Syntax only

The GQL parser accepts this form. The database does not currently execute it. The example below demonstrates grammar, not a runnable query feature.

CALL graph.expand($start) YIELD node AS n RETURN n;

Named calls, procedure reference parameters (CALL $proc(...)), OPTIONAL CALL and inline CALL [(bindings)] { ... } bodies are represented in the AST. There is no procedure registry or procedure execution API yet. YIELD here projects procedure outputs and is distinct from graph-pattern YIELD.

See supported features for executable alternatives.
