我有一些应用程序使用以下程序:
I have the following procedure which is used by some applications:
procedure p1
is
begin
bla bla bla;
end;
但是没有异常处理块.所以应用程序就是根据这个特性编写的.
But there is no exception handling block. So applications were written according this feature.
现在我需要在 p1 中记录错误.但它不应该影响使用此过程的应用程序.
Now I need to log errors in p1. But it shouldn't affect applications that use this procedure.
像这样:
procedure p1
is
begin
bla bla bla;
exception when others then
log_error(sqlcode, sqlerrm);
raise_new_exception (sqlcode, sqlerrm);
end;
如果出现 raise_application_error,第一个参数应该在 [-20000, -20999] 范围内.因此,如果引发异常 no_data_found,则不会引发此错误.
In case of raise_application_error first parameter should be in range [-20000, -20999]. So if there raises exception no_data_found, it cannot raise this error.
在exception_init 的情况下,第二个参数不应是可变的.它必须是数字文字.
In case of exception_init, second parameter should not be variable. It must be numeric literal.
PS:作为临时解决方案,我使用立即执行
PS: As temporary solution, I'm using execute immediate
如果你的错误依旧,改成
If your error stays the same, change to
...
exception when others then
log_error(sqlcode, sqlerrm);
raise;
end;
/
这在文档中进行了解释.
