Like Alex mentioned, the ORA-01403 is not thrown by the UPDATE, but by the SELECT. Make sure that P3_filename has a value and there is matching data in the table.

就像Alex提到的那样,ORA-01403不是由UPDATE引发的,而是由SELECT引发的。确保P3_filename具有值,并且表中存在匹配的数据。

Simple to prove this, just enclose the SELECT in an exception block like this:

很容易证明这一点,只需将SELECT包含在一个异常块中,如下所示:

....
BEGIN

  SELECT
    blob_content
  INTO
    l_upload_blob
  FROM
    apex_application_temp_files
  WHERE
    name = :P3_filename;

EXCEPTION
  WHEN NO_DATA_FOUND THEN
     <<Add your troubleshooting code here, like display the variable>>
END
.....

Maybe you use the SQL%ROWCOUNT to check the number of rows affected. Here is a good example for it.

也许您使用SQL%ROWCOUNT来检查受影响的行数。这是一个很好的例子。
