處理PL/SQL錯誤：捕獲異常，不把它

Question

我有引發此異常

error_stack -> ORA-00030: El identificador de sesión del usuario no existe. 
error_backtrace -> ORA-06512: en "OF_OWNER.GET_INVOICES", línea 46 
call_stack -> ----- PL/SQL Call Stack ----- 
    object  line object 
    handle number name 
00000010DB020548  59 procedure OF_OWNER.GET_INVOICES 
000000112A537E58   2 anonymous block 

一個過程，但我不希望程序提出任何例外在這種情況下，我已經試過

... 
WHEN 'ORA-00030' THEN 
WHEN OTHERS 
... 

但我得到一個編譯錯誤

或者：

BEGIN 
    do something 
EXCEPTION WHEN OTHERS THEN 
    IF SQLCODE = -30 THEN 
    NULL; -- ignore this particular exception 
    ELSE 
    RAISE; -- but throw the others 
    END IF; 
END; 

或者：

DECLARE 
    ORA00030 EXCEPTION; -- or any other name you like instead of ORA00030 
    pragma EXCEPTION_INIT(ORA00030, -30); -- link your exception name to the code 
BEGIN 
    do something 
EXCEPTION WHEN ORA00030 THEN 
    NULL; -- ignore this particular exception 
END;
