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.
