Oracle 12c 一次性解锁所有锁定用户

Question

您好，我想从 Oracle 12C 的 dba_users 中解锁用户列表。

我尝试过：

ALTER USER (SELECT username FROM dba_users WHERE ACCOUNT_STATUS LIKE '%LOCKED%') ACCOUNT UNLOCK;

ERROR at line 1:
ORA-01935: missing user or role name

任何想法 ？或者我必须为每个用户手动执行？

一种选择是编写一个查询，它将为您编写查询。例如：

SQL> select 'alter user ' || username || ' account unlock;' from dba_users;

'ALTERUSER'||USERNAME||'ACCOUNTUNLOCK;'
---------------------------------------------------------
alter user SUPERUSER account unlock;
alter user C##TEST account unlock;
alter user SYS account unlock;
alter user SYSTEM account unlock;
alter user ANONYMOUS account unlock;
alter user SUSHANT account unlock;
alter user SCOTT account unlock;
<snip>

现在，复制/粘贴上面的一堆ALTER USER语句，您将解锁所有人。

另一个是使用动态 SQL 的简单 PL/SQL 块（我只解锁用户 SCOTT；您可以解锁任何您想要的人）。

SQL> begin
  2    for cur_r in (select username from dba_users where username in ('SCOTT')) loop
  3      execute immediate 'alter user ' || cur_r.username || ' account unlock';
  4    end loop;
  5  end;
  6  /

PL/SQL procedure successfully completed.
