FRM-41009: Function key not allowed. Press %s for list of valid keys

有时候在触发器WHEN-CLEAR-BLOCK里头去clear_block('另外一个块')，会报FRM-41009的错误。

可以用下面的方法来忽略这个错误。

Even though you cannot suppress it, you can create an on-error trigger to intercept it and prevent from displaying:

DECLARE

ERR_VAL NUMBER(5)     := ERROR_CODE;

MSG     VARCHAR2(150)

:= SUBSTR('   '||ERROR_TYPE||'-'||TO_CHAR(ERR_VAL)||': '

||ERROR_TEXT,1,150);

BEGIN

IF ERR_VAL=41009 THEN

null;

ELSE

MESSAGE(MSG);

RAISE FORM_TRIGGER_FAILURE;

END IF;

END;
