Question

我在VehicleHistoryGraph数据库中创建了一个Message类型的顶点，并为其加载了50,000个此类型的顶点。

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，说某些顶点已被删除（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

Error: com.orientechnologies.orient.core.exception.OCommandExecutionException: Error on execution of command: sql.select from Message

orientdb {db=VehicleHistoryGraph}> DELETE VERTEX MESSAGE

orientdb {db=VehicleHistoryGraph}> SELECT COUNT(@rid) FROM Message

1 item(s) found. Query executed in 0.167 sec(s).

orientdb {db=VehicleHistoryGraph}> DELETE VERTEX MESSAGE

Delete record(s) '1820' in 6.320000 sec(s).

orientdb {db=VehicleHistoryGraph}>

出了什么问题？为什么？这是一个错误吗？

Answer 1

问题仍然存在吗？如果您尝试使用最新版本（从2.2.x版开始），则有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（用于修复数据库）

使用＆＃34; DELETE VERTEX时，OrientDB不会立即删除所有顶点...＆＃34; SQL语句
