-
-## orafce简介
-
-orafce是MogDB针对Oracle的兼容包，可以支持一些Oracle的表、函数和数据类型。orafce提供兼容Oracle RDBMS的函数和操作符。
-
-本插件包含一些实用功能，能够帮助将Oracle应用程序迁移到MogDB/PostgreSQL。内置Oracle日期函数已针对Oracle 10进行了一致性测试，支持从1960到2070的日期范围。由于Oracle内含的bug，目前无法验证1100-03-01之前的日期。
-
-所有函数与Oracle完全兼容，并支持所有已知格式的字符串。详细介绍参见[GitHub orafce页面](https://github.com/orafce/orafce)。
-
-> **注意**：orafce插件和whale插件不能同时使用，后续补丁版本将解决该问题。
-
- <br/>
-
-## orafce安装
-
-1. 访问[MogDB下载页面](https://www.mogdb.io/downloads/mogdb/)，下载所需版本的orafce插件。
-
-2. 解压插件包，例如：
-
-   ```SHELL
-   tar -xzvf orafce-3.17-3.1.0-01-CentOS-x86_64.tar.gz
-   ```
-
-3. 进入插件所在目录下，执行`make install`命令。
-
-   ```SHELL
-   cd orafce/
-   make install
-   ```
-
-4. 连接到数据库，执行`create extension orafce;`插件即可使用。

-
-## orafce简介
-
-orafce是MogDB针对Oracle的兼容包，可以支持一些Oracle的表、函数和数据类型。orafce提供兼容Oracle RDBMS的函数和操作符。
-
-本插件包含一些实用功能，能够帮助将Oracle应用程序迁移到MogDB/PostgreSQL。内置Oracle日期函数已针对Oracle 10进行了一致性测试，支持从1960到2070的日期范围。由于Oracle内含的bug，目前无法验证1100-03-01之前的日期。
-
-所有函数与Oracle完全兼容，并支持所有已知格式的字符串。详细介绍参见[GitHub orafce页面](https://github.com/orafce/orafce)。
-
-> **注意**：orafce插件和whale插件不能同时使用，后续补丁版本将解决该问题。
-
- <br/>
-
-## orafce安装
-
-1. 访问[MogDB下载页面](https://www.mogdb.io/downloads/mogdb/)，下载所需版本的orafce插件。
-
-2. 解压插件包，例如：
-
-   ```SHELL
-   tar -xzvf orafce-3.17-3.1.0-01-CentOS-x86_64.tar.gz
-   ```
-
-3. 进入插件所在目录下，执行`make install`命令。
-
-   ```SHELL
-   cd orafce/
-   make install
-   ```
-
-4. 连接到数据库，执行`create extension orafce;`插件即可使用。
-
-   ```sql
-   MogDB=# create extension orafce;
-   CREATE EXTENSION
-   ```
-
- <br/>
-
-## orafce创建及使用
-
-```sql
-create extension orafce;
-```
-
-检查所有模式：
-
-```sql
-\dn
-```
-
- <br/>
-
-### dbms_output 使用方法
-
-检查函数，其中函数分为有参数、无参数，参数类型为boolean。
-
-```sql
-\df dbms_output.*
-```
-
-无参：
-
-```sql
-select dbms_output.disable();
-```
-
-有参：
-
-```sql
-select dbms_output.put_line('sss');
-```
-
-boolean：（这里boolean值为0、1）
-
-```sql
-select dbms_output.serveroutput(0);
-```
-
-<br/>
-
-### dbms_random使用方法
-
-检查函数，函数分为有参、无参
-
-```sql
-\df
-```
-
-有参：
-
-```sql
-select dbms_random.initialize(1);
-select dbms_random.value(256.1243434351237831823812312,12333.3111);
-```
-
-value可以不传参数。

-
-### dbms_utility使用
-
-检查函数
-
-```sql
-\df
-```
-
-```sql
-select dbms_utility.format_call_stack();
-select dbms_utility.format_call_stack('o');

-
-（参数必须为'icnsmx'一个或多个组合，会把m转换为n，n转换为s，boolean为true，字符串后边会添加一个g，false不添加）
