Good point. java.math.BigInteger has unlimited precision, I dont think there is
a sql type equivalent to it. The close I think is decimal.
In JavaToSqlTypeConversionRules, we are mapping BigDecimal(unlimited precision)
to Sql.Decimal already, so I think we can convert BigInteger to Sql.Decimal as
well. Transact-SQL do conversion of integer to Decimal if it's outside the
integer range.
