I am read a documentation - and I am not sure. It is not part of SQL/PSM. It is part of Foundation (SQL/Foundation) - see CD 9075-2:200x(E) 11.50 <SQL-invoked routine>. Important is section 18.d. one parameter from all parameter list have to be unique (types are not compatible) Section 9.18 Data type identity speaking what are identity types, but I am missing definition what are not compatible types. so I if I respect 18.d, then I have not a functions foo(varchar(30)) and foo(varchar(40)). But i am not native speaker and SQL standard is cryptographic for me. Please, can somebody check it again.
