我使用Box_caring功能插入三个表,插入正确,但如果在插入表格之间出现一些错误,则不会滚动数据。
我正在寻找以下挑战的解决方案:拥有一组相关的表格。它们与主/外键关系相关,需要更新/插入相关表中的对象。在迭代器中介内插入/更新。当其中一个更新/插入失败时会发生什么?是否会回滚所有插入/更新的对象?
请提供任何想法或链接或代码段以使其有效。
注意:我使用的是wso2 esb-4.8.1,wso2 dss-3.2.2和MSSQL数据库

在这里,您必须实现分布式XA事务。您能否参考文章[1],它将指导您完成此任务。

使用box_carring功能时,必须在所有操作调用中保持相同的会话。否则,它将作为单独的调用进行求值,并且不会是原子的。这是一个示例synapse配置,可用于维护相同的会话。

但是,您可以使用request_box功能,无需在整个操作过程中维护会话。
