OrientDB使用 "DELETE VERTEX ..."SQL语句时不会一次删除所有顶点

Question

我在 VehicleHistoryGraph 数据库中创建了一个 Message 类型的顶点，并向其中加载了 50,000 个该类型的顶点。

当我尝试使用此 SQL 语句一次删除所有顶点时 -

DELETE VERTEX MESSAGE

我收到意外错误，指出某些顶点已被删除(但另一方面，我在加载后没有删除任何顶点)，并且顶点不会按预期一次性删除所有顶点(见下文)。

orientdb> connect remote:localhost/databases/VehicleHistoryGraph admin admin

 Connecting to database [remote:localhost/databases/VehicleHistoryGraph] with user 'admin'...OK
orientdb {db=VehicleHistoryGraph}> DELETE VERTEX MESSAGE

出了什么问题？为什么？这是一个错误吗？

Answer 1

问题还存在吗？如果您尝试使用最新版本(从 2.2.x 开始)，有 2 个有用的命令:

CHECK DATABASE (检查数据库的完整性。如果数据库包含图形，则检查其一致性)

REPAIR DATABASE (修复数据库)
