APEX

I have to store graphical documents in an Oracle Database using Apex. I have designed an application based on the Sample Application for Customers, Product, Orders Page 3 and 6 using apex_util.get_blob_file_src and a File Browse Item to store the document in a BLOB field. That works perfectly.

Now I had to change the application to store the BLOB content in a file and set a pointer in a BFILE column leaving the BLOB column empty. Therefore I wrote a view converting BFILE to BLOB and some instead of triggers to convert BLOB to BFILE.

Then I rewrote my Apex pages using the view instead of the table. It doesn’t work. I noticed that when using the table Apex is first executing an INSERT leaving the BLOB empty and after that an UPDATE to fill the BLOB column when creating a new record. When using the view instead of the table the INSERT is executed but not the UPDATE.

So I wanted to write a page process to update the table manually. But I found that there was no entry in the view APEX_APPLICATION_FILES generated by Apex. So I have no chance to obtain the BLOB value and use it to update my table.

What can I do to have the BLOB content written by Apex to the table the view APEX_APPLICATION_FILES is selecting from?
