Question

我有以下Select查询，它将生成删除语句以删除模式中的所有对象。

select 'DROP '||OBJECT_TYPE||' '||OWNER||'.'||OBJECT_NAME
       || case when OBJECT_TYPE = 'TABLE'
               then ' CASCADE CONSTRAINTS PURGE' else '' end
       ||';' 
  from all_objects
 where OWNER = 'RATOR_MONITORING';

我想创建批处理文件，并假设我可以创建可能是游标或其他内容而不是生成删除语句，并将其保存在批处理文件中并运行批处理文件以删除架构中的所有内容。怎么做？

Answer 1

这是脚本

begin
  for i in (select * from dba_objects where owner = 'SO' and object_type <> 'TABLE')
  loop
    execute immediate 'drop ' || i.object_type || ' ' || i.object_name;
  end loop;
  for j in (select * from dba_objects where owner = 'SO' and object_type = 'TABLE')
  loop
    execute immediate 'drop ' || j.object_type || ' ' || j.object_name || ' cascade constraints';
  end loop;
end;

您可以在Internet上找到许多脚本。它们都不是100％工作。我们可以有各种各样的陷阱。像调度程序链或物化视图组一样。

这是我使用的那个（它的灵感来自我在互联网上找到的那个）

set serveroutput on size unlimited
declare
  v_ItemCount integer;
begin
  SELECT count(*)
    INTO v_ItemCount
    FROM ALL_OBJECTS AO
   WHERE AO.OWNER = '&USER'
     AND AO.OBJECT_TYPE NOT IN ('INDEX', 'LOB')
     AND AO.OBJECT_NAME NOT LIKE 'BIN$%';
  while (v_ItemCount > 0) loop
    for v_Cmd in (SELECT 'drop ' || AO.OBJECT_TYPE || ' ' || '"'||AO.OWNER||'"'|| '.' || '"'||AO.OBJECT_NAME||'"' ||
                         DECODE(AO.OBJECT_TYPE,
                                'TABLE',
                                ' CASCADE CONSTRAINTS',
                                '') as DROPCMD,
                                AO.OWNER,
                                AO.OBJECT_TYPE,
                                AO.OBJECT_NAME
                    FROM ALL_OBJECTS AO
                   WHERE AO.OWNER = '&USER'
                     AND AO.OBJECT_TYPE NOT IN ('INDEX', 'LOB')
                     AND AO.OBJECT_NAME NOT LIKE 'BIN$%') 
    loop
      begin
        if v_Cmd.OBJECT_TYPE = 'SCHEDULE' then
          DBMS_SCHEDULER.DROP_SCHEDULE(v_Cmd.OWNER||'.'||v_Cmd.OBJECT_NAME, true);
        ELSIF v_Cmd.OBJECT_TYPE = 'JOB' then
          DBMS_SCHEDULER.DROP_JOB(v_Cmd.OWNER||'.'||v_Cmd.OBJECT_NAME, true);
        ELSIF v_Cmd.OBJECT_TYPE = 'PROGRAM' then
          DBMS_SCHEDULER.DROP_PROGRAM(v_Cmd.OWNER||'.'||v_Cmd.OBJECT_NAME, true);                              
        else
          execute immediate v_Cmd.dropcmd;
        end if;  
        dbms_output.put_line(v_Cmd.dropcmd);        
      exception
        when others then
          null; -- ignore errors
      end;
    end loop;
    SELECT count(*)
      INTO v_ItemCount
      FROM ALL_OBJECTS AO
     WHERE AO.OWNER = '&USER'     
       AND AO.OBJECT_TYPE NOT IN ('INDEX','LOB')
       AND AO.OBJECT_NAME NOT LIKE 'BIN$%';
  end loop;
  execute immediate 'purge dba_recyclebin';
end;

Here we go i have compiled a shell to perform the Purge Schema. Let me know if this helps.
