弹出“FRM-40400：事务完成：已应用和保存X条记录

每次成功退出保存修改或添加记录时窗体都会弹出“FRM-40400：事务完成：已应用和保存X条记录。"
的消息窗，可不可以在适当的触发器中改变它的属性？

1.

:system.message_level :=10;
commit;
:system.message_level :=10;

就不会有任何显示。
------------------------------------------

l_level := :system.message_level;

:system.message_level :=25;
commit;
:system.message_level :=l_level;

*提示信息如果小于20，系统隐藏消息。

*如果等于25，则有异常会产生报警。

*值越大，系统所能显示的提示信息越严重！（每个系统消息有一个严重等级），你可以使用这个变量来屏蔽一些你认为不需要的系统消息

SYSTEM.MESSAGE_LEVEL stores one of the following message severity levels: 0, 5, 10, 15, 20, or 25. The default value is 0.
SYSTEM.MESSAGE_LEVEL can be set to either a character string or a number. The values assigned can be any value between 0 and 25, but values lower than 0 or higher than 25 will generate an error.
During a Runform session, Form Builder suppresses all messages with a severity level that is the same or lower (less severe) than the indicated severity level.

Assign a value to the SYSTEM.MESSAGE_LEVEL system variable with standard PL/SQL syntax:

:System.Message_Level := value;

The legal values for SYSTEM.MESSAGE_LEVEL are 0, 5, 10, 15, 20,and 25.  Form Builder does not suppress prompts or vital error messages, no matter what severity level you select.

在ON-MESSAGE事件
begin
       if message_code in (40400,40401,40406,40407)   then
         clear_message;
end if;
end;
