Describe your feedback
when you pass a very large number (larger than max long, but smaller than max UInt64) as a string in a simple insert, the client attempts to convert this value into a long using Long.parseLong, which will fail, as the string value is higher than the long boundary. something like BigInteger.longValue would be required for this translation.
Code example
preparedStatement.setString(1, bignumber);
preparedStatement.addBatch();
