Solutions

1. The function takes no parameters, but arguments were supplied.
2. Call the function with no arguments, e.g. current_date() with no args.

When it happens

Trigger: A function call in a query supplies arguments that violate the function's signature.

Common situations: Passing the wrong number or types of arguments (e.g. untyped nulls, tuples) to HQL/SQL functions.
