Hi Laurent – this sounds that generally operators do not have parenthesis at all – but the in list operator has parenthesis.
Greetings

note that connect_by_root is not a function but an operator, so the parentheses are meaningless.

select connect_by_root ename root from empconnect by mgr = prior empno;

nice piece of code!
