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

Both BigInteger and BigDecimal extend java.lang.Number, however this does not mean that you can cast from BigInteger up to Number then down to BigDecimal.

There is a constructor in BigDecimal that takes a BigInteger, so try:

BigDecimal d = new BigDecimal(b);
