文档解释

ORA-22839: Direct updates on SYS_NC columns are disallowed

Cause: An attempt was made to update SYS_NC columns directly.

Action: Avoid direct updates on SYS_NC columns.

ORA-22839错误提示是：“Direct updates on SYS_NC columns are disallowed.”当在SYS_NC列上进行直接更新时会抛出此错误。

SYS_NC是Oracle系统引导表的列名。这些表包含了Oracle数据库引导所需的重要系统数据。在DBA_USERS或ALL_USERS表中查看OBJECT_TYPE列，如果取值为SYS_NC，则说明该表是一个系统引导表。

如果应用程序中直接向这些表中写数据，就会发生ORA-22839错误。应用程序应该避免直接向SYS_NC表写数据，尽量使用受控的数据库对象，如视图和存储过程，以便安全地更新系统表中的数据。
