Question

我尝试了以下链接的步骤：

https://slobaray.com/tag/execute-shell-script-from-plsql/

它包含在

中

使用

创建存储为BASH_OS函数的java对象

CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED "BASH_OS"..

然后用

执行java

 CREATE OR REPLACE PROCEDURE unix_command (p_command  IN  VARCHAR2)
 AS LANGUAGE JAVA 
 NAME 'BASH_OS.executeCommand (java.lang.String)';

但它显示

the object BASH_OS does not exist.

任何人都可以帮助我了解如何使用此方法从Toad执行shell脚本吗？

或者是否还有其他方法可以从Toad调用shell脚本？

引用您的链接，我发现第13行中的类名称对于创建BASH_OS是错误的。

类名称应为“ BASH_OS”，而不是“ Host”。由于博客上没有评论功能，因此我将固定代码复制到此处。

CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED "BASH_OS" AS
