You cannot import a dump file from PL/SQL developer.您不能从 PL/SQL 开发人员导入转储文件。 Instead, you have to do it from the command line.相反，您必须从命令行执行此操作。 Furthermore, you need access to the file system of the database server since you have to put the dump file in a directory directly accessible by Oracle.此外，您需要访问数据库服务器的文件系统，因为您必须将转储文件放在 Oracle 可直接访问的目录中。

The tool to import the dump file is called impdp (in earlier version, it was imp ).导入转储文件的工具称为impdp （在早期版本中，它是imp ）。

My experience is that you need information how the dump file was created so you can use the correct import mode:我的经验是，您需要了解如何创建转储文件，以便使用正确的导入模式：

Is it a dump of the full database or just a single user/schema?它是完整数据库的转储还是单个用户/模式？
Does it include the table schema or just the table data?它是否包含表模式或仅包含表数据？
What's the schema/user name if a single schema was exported?如果导出单个架构，架构/用户名是什么？
etc.等等

You'll find more information about impdp on this PSOUG web page .您可以在此PSOUG web 页面上找到有关impdp的更多信息。
