How to re-raise pl/sql exception in exception handling block?

oracleexception-handlingplsql

提问by user2090855

I have the following procedure which is used by some applications:

我有一些应用程序使用以下程序:

procedure p1
is
begin
  bla bla bla;  
end;

But there is no exception handling block. So applications were written according this feature.

但是没有异常处理块。所以应用程序是根据这个特性编写的。

Now I need to log errors in p1. But it shouldn't affect applications that use this procedure.

现在我需要在 p1 中记录错误。但它不应影响使用此过程的应用程序。

Something like this:

像这样的东西:

procedure p1
is
begin
  bla bla bla;

  exception when others then
    log_error(sqlcode, sqlerrm);
    raise_new_exception (sqlcode, sqlerrm);
end;

In case of raise_application_errorfirst parameter should be in range [-20000, -20999]. So if there raises exception no_data_found, it cannot raise this error.

如果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 exception_init, second parameter should not be variable. It must be numeric literal.

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。

PS: As temporary solution, I'm using execute immediate

PS:作为临时解决方案,我正在使用立即执行

If your error stays the same, change to

如果您的错误保持不变,请更改为

...
exception when others then
  log_error(sqlcode, sqlerrm);
  raise;
end;
/

This is explained in the documentation.

在文档中进行了解释。
