oracle中写java代码,并调用

1.创建java source

create or replace and compile java source named tony as
public class tony
{
public static String getStrMsg(String str)
{
return str+"\t 共有字符:"+str.length()+"个";
}
}

2.创建调用函数

create or replace function javaTest(str varchar2)
return varchar2 as
LANGUAGE JAVA NAME 'tony.getStrMsg(java.lang.String) return java.lang.String';

3.执行测试

select javatest('abcd') from dual ;

4.结果

abcd 共有字符:4个
