}
Derived[] v = new Derived[2];
Square (v);
By normal conversion rules, a Derived[] is convertible to a Base[] (for better or worse), so if you s/struct/class/g for the above example, it'll compile and run as expected, with no problems. But if Base and Derived are valu...
What is the difference between varchar and varchar2 in Oracle?
...
As for now, they are synonyms.
VARCHAR is reserved by Oracle to support distinction between NULL and empty string in future, as ANSI standard prescribes.
