Обсуждение: what is the error in the function?

Dear Sirs:

Please I have a function as:

create function nr_renewLease(varchar(15),interval)
returns integer as '
DECLARE
 local_address ALIAS FOR $1;
 lease_duration ALIAS FOR $2;
BEGIN
  update nr_lease set expires=now()+lease_duration where
  address=local_address;
END;
return 1;
'
language 'plpgsql';

When I called this function so:

select nr_renewlease('111.111.111.111','50 seconds')

I get the follow error :

ERROR:  Function 'nr_renewlease(unknown, unknown)' does not
exist Unable to identify a function that satisfies the given
argument types You may need to add explicit typecasts.

I don't know where is the fail.

I will thank if you can help me to clarify this.

Regards,

Ernesto

As the error message suggests you may need to cast the types so that it knows what kind of data you are putting in,
perhapslike so: 

select nr_renewlease('111.111.111.111'::VARCHAR,'50 seconds'::TIMESTAMP)

I am not sure, look it up in the docs.

Aasmund.
