Question

我正在开发Oracle APEX（ Oracle APEX 5.03.00.03 on Oracle 11.2.0.1.0 ）项目，并希望在经典报告中添加BLOB下载字段。当我尝试实现内置BLOB函数时，当我尝试使用下载功能时出现以下错误：

在此服务器上找不到请求的网址/apex/apex_util.get_blob

当我只显示包含BLOB的表的ID时，它似乎工作正常。

有人可以建议我收到此错误消息的原因吗？

详细错误消息：

Answer 1

您需要将这些内容添加到您的页面

隐藏页面项目，例如 P60_DOC_ID
一个文件浏览页面项目，例如 P60_DOC
页面标题执行点之后的自动行提取过程，比方说 FETCH DOC

然后你可以用以下方式实现内置的BLOB功能，

APEX_UTIL.GET_BLOB_FILE_SRC('P60_DOC',DOC_ID,NULL,'inline')

项目和流程属性的屏幕截图供参考，

APEX 5 get_blob不起作用
