> Defining a column in the returned type as CHAR(10) requires that the returned value be
of length 10 characters.
> Defining a table function with a return type of:
>    returns TABLE  column0 char( 10 ), column1 char( 10 ))
> seems to just return whatever the Java ResultSet implementation handed it.
> My guess this is true for all variable length types, no casting of the value occurs when
it is returned to the SQL domain.
> Java single value functions and procedure out parameters do perform any required casting
to ensure the value is of the declared type.
