文档解释

ORA-18119: XUDY0020 – Deleted node has no parent

Cause: Node was deleted that had no parent before execution of the query began.

Action: None

ORA-18119：XUDY0020-删除的节点没有父节点。

官方解释

ORA-18119的错误消息提供用户/管理员的指示，表明尝试删除的节点没有父节点。根据节点结构，必须存在父节点，否则删除操作将失败。

常见案例

ORA-18119是在尝试删除一个不存在父节点的节点时出现的。

一般处理方法及步骤

1.首先，检查尝试删除的节点是否具有父节点。

2.如果确实没有父节点，可以尝试级联删除并确保该节点有一个父节点。

3.如果级联删除也失败，尝试分离该节点，以便可以分别处理父节点和子节点。

4.分离子节点之后，可以选择将子节点重新连接到其他节点上，或者重新连接到原有父节点上。
