Question

我有一个使用执行立即更改用户密码的过程。如果密码正确，则会将结果（带有一些附加文本的新密码）传递给OUT参数关键是如何将密码验证功能的结果错误（如下所示）传递给OUT参数：

ORA-28003: password verification for the specified password failed
ORA-20004: Password should contain at least one digit, one character and one
punctuation

你会给我一些提示/例子吗？

在我的程序代码下面：

CREATE OR REPLACE procedure SYS.SYSChangePassword(
  pUsername in varchar2, 
  pNewPassword in varchar2,
  pResult out varchar2(300))  as

begin
    execute immediate 'alter user '||pUsername||' identified by "' || pNewPassword || '";';
    pResult := 'New password for '|| pUsername||' has been set:  '|| pNewPassword ;
end;
/

Answer 1

在过程编译期间，不能为out变量varchar2(300)指定大小。

CREATE OR REPLACE procedure SYSChangePassword(
  pUsername in varchar2, 
  pNewPassword in varchar2,
  pResult out varchar2 )  as

begin
    execute immediate 'alter user '||pUsername||' identified by "' || pNewPassword || '";';
    pResult := 'New password for '|| pUsername||' has been set:  ' || pNewPassword ;

    EXCEPTION
    WHEN OTHERS THEN
    pResult := SQLERRM;
end;
/

现在，您可以调用该过程并显示错误消息。

DECLARE
vResult varchar2(400);
BEGIN
SYSChangePassword (pUsername=>'HR',pNewPassword=> 'hr',pResult=>vResult );

DBMS_OUTPUT.PUT_LINE(vResult);
END;
/

Answer 2

Somehing如：

b'name=test&password=tttt'
