有没有办法使用文本编辑器查看用于导出 Oracle 转储 (dmp) 文件的字符集？
我知道我可以在 .dmp 文件中看到 Oracle 版本 - 它以明文形式显示。
但是，我可以看到字符集吗？它似乎在任何地方都不是明文，但我猜它在“某处”，也许是十六进制？
我问的原因是我收到一条消息，说明在尝试导入时，导入服务器字符集与 .dmp 文件中的字符集之间存在潜在冲突。但是，警告没有显示 export 字符集。它对两者都说 'Import'，我认为这是一个误导性消息 - 因此想要检查 .dmp 文件以获取信息。
谢谢。

这是出口：
E:\>exp scott/tiger@orcl file=scott.dmp
Export: Release 11.2.0.3.0 - Production on Wed Mar 11 11:49:56 2020

Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Productio
With the Partitioning, Real Application Clusters, Automatic Storage Management, OLAP,
Data Mining and Real Application Tes
Export done in WE8MSWIN1252 character set and AL16UTF16 NCHAR character set

. exporting pre-schema procedural objects and actions
. exporting foreign function library names for user SCOTT
EXP-00091: Exporting questionable statistics.
. . exporting table EMP 14 rows exported
<snip>
. exporting statistics
Export terminated successfully with warnings.
结果是scott.dmp 文件。如果您使用show=y import 的选项，则不会导入任何内容，但您会看到导出对象的列表。您对前几行感兴趣：
E:\>imp scott/tiger@orcl file=scott.dmp show=y
Import: Release 11.2.0.3.0 - Production on Wed Mar 11 11:50:17 2020

我猜你看到提到的字符集，不是吗？希望对您有所帮助。
【讨论】：
import done in WE8MSWIN1252 character set and AL16UTF16 NCHAR character set 或 import server uses EE8MSWIN1250 character set (possible charset conversion) 他们都指定“导入”
