SQL XML XMLELEMENT - 将更多内容放入根 header
SQL XML XMLELEMENT - puuting more into root header
我创建了一个 XML SQL 查询，但我发现很难找到在 XML 的 header 中添加更多内容的解决方案（请参阅以下）。对于从数据库 table 带回的每条生产记录，必须有一个 parent header <message> 标记，并且在该消息标记内 <messageSequenceId> 有一个记录计数（即数字，第一个生产记录为 1，第二个生产记录为 2，依此类推...）。
交付标签 <delivery> 只在顶部出现一次，并且在顶部也有一个完成标签 </delivery> .
还有一个<AV-XML>，它在输出的开始处有一个标签，在输出的结尾处有一个结束标签。
请参阅下面的输出示例。我只需要这些来完成程序。
提前感谢我收到的任何回复。

看起来 Message 是 Production 的外部元素，而 messageSequenceId 只是主查询的 rownum - 类似于您的方式在内部查询中重新获得 cueID。
因此您可以将查询修改为 XML消息上的 Agg 而不是生产；然后有一个顶级 AV-XML 节点，其中包含一个新的传递元素和消息聚合。

你还没有说 creationDateTime 和 deliveryNo 来自哪里，所以我猜他们都应该是提取时间（从 systimestamp 得到时区偏移量），但您可能有另一种方法来生成它们。
