how to store BigInteger values in oracle database

Question

I have connected Java program to Oracle database using JDBC. I want to store BigInteger values(512 bits) in the database. What should be the type of the column?

Answer 1

I'm not answering directly your question, but i only see one oracle datatype that can store a 512 bits number : varchar2(156) (156 = abs(log(2^512))+2)

So i would rather convert the biginteger to a string rather than a bigdecimal.
