Question

是否可以在openjpa切片上对createNativeQuery使用executeUpdate？我们尝试过类似的东西，但不会更新任何记录。我们正在使用 MySQL数据库。日志显示更新将转到两个切片并立即回滚。没有切片，一切都很好。

String updateQueryString = "update address set name = ?1 ";
 Query query = JPA.em().createNativeQuery(updateQueryString)
.setHint("openjpa.hint.slice.Target", “One”)
                .setParameter(1, "adr1");
query.executeUpdate();

我们的persistence.xml文件：
