如何在 pl/sql 中将 .dmp 文件转换为 .sql 文件答案

【问题标题】：How to convert .dmp file to .sql file in pl/sql如何在 pl/sql 中将 .dmp 文件转换为 .sql 文件
【发布时间】：2020-07-29 10:55:49
【问题描述】：

我无法将 .dmp 文件转换为 .sql。

Database username=chartindia
Database password=gaurav12

我正在使用的代码：

exp chartindia file=D:\\chartindia2020.dmp

我是 pl/sql 的新手。

【解决方案1】：

我认为你做不到。

DMP 扩展 - 在 Oracle 世界中 - 表示导出操作（由 original EXP 实用程序或 modern Export Data Pump）产生的文件。不管它是什么，file 都不是 textual 文件，您不能只是 读取它 并将其转换为 .SQL。此外，您想到了什么样的 .SQL？插入语句？创建这个和那个？

如果您想将 DMP 文件的内容导入数据库，您可以使用 IMP 实用程序（或 Import Data Pump）。这是正确的做法。

PL/SQL 与该操作无关。

【讨论】：

【解决方案2】：

要提取使用 Datapump 创建的 DMP 文件的 DDL，您可以使用带有选项 sqlfile 的导入实用程序

例子

impdp directory=yourdirectory dumpfile=yourdumpfile sqlfile=mysqlscript.sql

但是，请考虑到这一点

必须使用 Datapump expdp 创建原始 DMP 文件
SQLFILE 只检索转储文件中的 DDL 操作。它不会将任何 DML 脚本写入 sqlfile。

据我所知，您无法将使用 exp（旧实用程序）创建的原始 dmp 文件转换为 sqlfile，甚至对于 ddls 也不行。

更新

好吧，如果我没记错的话，在我以前的 9i 时代，Oracle Support 有一个名为 DUL 或 DataUnLoad 的内部实用程序，它能够读取二进制文件或数据库数据文件以提取数据。但这是一个非官方工具，仅由 Oracle 支持部门处理。

示例

假设我想在一个模式中获取对象的 DDLS

SQL> select object_name, object_type from dba_objects where owner = 'TEST_PERF' order by object_type, object_name ;

你首先（如果你没有的话）创建一个数据库目录

 SQL> CREATE OR REPLACE DIRECTORY MY_DIR AS '/mypath' ;

 SQL> GRANT READ,WRITE ON DIRECTORY MY_DIR to MY_SCHEMA ;

然后

$ expdp directory=DIR_DATAPUMP_EXPORT dumpfile=mytestfile.dmp schemas=test_perf

【讨论】：

你能给我一个使用上面代码的例子吗？
@GauravKumar，我举了一个例子，请接受并支持答案
但我仍然没有得到答案。
您就在那里找到了答案。当我向您展示如何使用数据泵导入选项 sqlfile 生成脚本时，我构建了一个测试用例
我放弃了投票，但弹出窗口显示感谢您的反馈，但数字没有改变
