我们正在使用 Boomi 在数据库和 MS Access 数据库之间进行集成。我们使用 uCanAccess 作为 JDBC，因此我们可以读/写 MS Access DB。
但是，如果我们的初始查询返回超过 49 行，我们会从 Boomi 收到以下错误，然后是 uCanAccess。我尝试使用流控制一次只处理 10 个文档，但这不起作用。同样的错误。我尝试更改批次计数。没有什么。
RYN-EMPDATA-BadgeDB 的测试执行完成但出现错误。嵌入消息：定时器已取消。
uCanAccess 站点 版本 3.0.6，带有推荐的 Jackcess 和 HSQLDB 版本
插入操作成功，但更新操作不成功。我们正在使用从访问文件导入的动态更新数据库配置文件。
一些新信息。事实证明，失败来自特定记录。我认为它在抱怨传递了一个 NULL 值，但我不能 100%
这是 Java 错误的顶部：

9/6 经过广泛的测试后，问题的原因与进入其中一个字段中包含二进制数据的字段有关。我们没有更新该字段，但由于某种原因，一旦 uCanAccess 遇到具有二进制数据（程序存储的照片）的行，它就会失败。
以下是尝试通过 uCanAccess 控制台更新同一记录的输出：
UCanAccess>update badgelisting set firstname="Test", lastname="stuff", active="false" where idnumber=58;
