在Oracle中重编译所有无效的存储过程

SQL_PLUS中
spool ExecCompProc.sql
select 'alter procedure '||object_name||' compile;' From all_objects where status = 'INVALID' and object_type = 'PROCEDURE';
spool off
@ExecCompProc.Sql; 

整理成一个存储过程
Create Or Replace Procedure Zl_Compile_Invalid_Procedure As
 Strsql Varchar2(200);
Begin
 For x In (Select Object_Name From All_Objects Where Status = 'INVALID' And Object_Type = 'PROCEDURE') Loop
  Strsql := 'Alter Procedure ' || x.Object_Name || ' Compile';
  Begin
      Execute Immediate Strsql;
      Exception
          --When Others Then Null;     
     When OTHERS Then dbms_output.put_line(Sqlerrm);     
  End;
 End Loop;
End;

执行
exec Zl_Compile_Invalid_Procedure;
如果要看到无法重编译的过程的出错信息,需要执行前设置set serverout on
