Question

我们正在使用Boomi在DB和MS Access DB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，反过来又会收到uCanAccess。我尝试使用流量控制，以便一次只处理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。

完成RYN-EMPDATA-BadgeDB的测试执行时出错。嵌入消息：定时器已取消。

uCanAccess site 使用推荐的Jackcess和HSQLDB版本的3.0.6版

插入操作成功但更新操作没有。我们正在使用从Access文件导入的动态更新数据库配置文件。

一些新信息。事实证明失败来自一个特定的记录。我认为它抱怨通过了NULL值，但我不能100％

以下是Java错误的顶部：

9/6经过大量测试后，问题的原因与到达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的行（程序存储的照片），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>UCAExc:::3.0.6 null

Answer 1

其中很多都归结为计时。如果有人在处理之前就在数据库中，我会收到错误。此外，我不得不将处理分成30个项目。然后我必须设置一个在每次运行后运行紧凑/修复的进程，因为它使DB膨胀大约30％。

至于Boomi，写入AccessDB应该是一项简单的任务。我不应该回到UCanAccess来完成这项工作。

Boomi Timer中的uCanAccess错误已经取消
