如何在PreparedStatement中处理(可能)空值？

String value = null;
PreparedStatement ps = connection.prepareStatement("INSERT INTO table_name (column_name) VALUES (?)");
ps.setObject(1, value, java.sql.Types.VARCHAR);
ps.executeUpdate();

String value = null;
PreparedStatement ps = connection.prepareStatement("INSERT INTO table_name (column_name) VALUES (?)");
if (value == null) {
    ps.setNull(1, java.sql.Types.VARCHAR);
} else {
    ps.setString(1, value);
}
ps.executeUpdate();

Optional<String> value = Optional.ofNullable(null);
PreparedStatement ps = connection.prepareStatement("INSERT INTO table_name (column_name) VALUES (?)");
ps.setString(1, value.orElse(null));
ps.executeUpdate();
