【中文标题】PL/SQL 中的问题 = 错误堆栈：ORA-01403：Oracle Application Express (APEX) 中没有数据【英文标题】：Problem in PL/SQL = Error Stack: ORA-01403: No Data in Oracle Application Express (APEX) 【发布时间】：2020-07-31 10:58:09 【问题描述】：

我创建了一个带有 Web 服务的上传系统（上传到 Oracle 存储桶）。我已将页面和 Web 服务复制到我的新应用程序（从已经运行的应用程序），但上传功能出现问题。我得到的错误是 ORA-01403: No Data，在原始页面中没有问题，一切正常。有人可以帮我解决这个问题或给我一个好的方向。

PL/SQL 代码

begin declare
  l_request_url varchar2(32767);    
  l_content_length number;    
  l_response clob;    
  upload_failed_exception exception;    
begin    
  for file in (    
  select * from apex_application_temp_files    
  where name = :P101_FILE    
  ) loop    
  l_request_url := :G_BASE_URL || 'b/##BUCKETNAME##'    
  || '/o/' || apex_util.url_encode(file.filename);    
    
  apex_debug.info('File: %s', file.filename);    
  apex_debug.info('URL: %s', l_request_url);    
  apex_debug.info('Mime: %s', file.mime_type);    
    
  apex_web_service.g_request_headers(1).name :=    
  'Content-Type';    
  apex_web_service.g_request_headers(1).value :=    
  file.mime_type;    
  l_response := apex_web_service.make_rest_request(    
  p_url => l_request_url    
  , p_http_method => 'PUT'    
  , p_body_blob => file.blob_content    
  , p_credential_static_id => :G_OCI_WEB_CREDENTIAL    
  );    
  if apex_web_service.g_status_code != 200 then    
  raise upload_failed_exception;    
  end if;    
  end loop;    
end;  
end;

P101_FILE = 上传文件项

##BUCKETNAME## = 在原始代码中是存储桶的实际名称。

【问题讨论】：

您没有找到任何数据，只能在select * from apex_application_temp_files where name = :P101_FILE 中使用 APEX SQL Workshop 并检查该表中是否有数据 还要检查:P101_FILE是否是顶点页面中元素的实际名称 :g_base_url 和 :g_oci_web_credential 是否分配了正确的值？这是从哪里引发的“uploadFile”中的“异常”？ apex_application_temp_files 是 P101_FILE 文件上传项的临时存储。在 DEBUG 中，我得到了所有信息（文件名/mime 类型和构造的 URL）。 两个应用程序中的替换完全相同。 URL(l_request_url) 是按照应有的方式构建的。 【参考方案1】：

问题是 :G_OCI_WEB_CREDENTIAL 的替换中的空格。删除空间后，一切正常。感谢您的帮助！
