Rechange the Process

Question

Hi friends,
im recently involved in uploading images in the report, and i have done it by following the below link....
http://apex.oracle.com/pls/apex/f?p=267:11
This is the page process that i found for uploading the images in the table a_images
BEGIN
IF (:P11_FILE IS NOT NULL) THEN
INSERT INTO A_IMAGES (FILE_NAME, BLOB_CONTENT, MIME_TYPE)
SELECT FILENAME, BLOB_CONTENT, MIME_TYPE
FROM APEX_APPLICATION_FILES WHERE NAME = :P11_FILE;
DELETE FROM APEX_APPLICATION_FILES WHERE NAME = :P11_FILE;
END IF;
END;I need a little change of the above page process for my scenario, since i dont want an image id that will be generated according to the sequence for the above example......
Instead i need an Employee_Number, but that is not generated in sequence......But it is of whoever the user who logs in to the application(i.e the APP_USER).......
For that i have recreated the table as my table consist of the following columns
*) employee_number--------->not null and it is the primary key column
*) file_name----------> not null column
*) mime_type
*) blob
so, in order to upload the image
I have created two page item
*)p2_employee_number----->which will appear in the default manner in the field for those whoever logsin to the application(APP_USER)
*)p2_blob_content------------>a filebrowse item(inorder to upload an image)
And also i have an UPLOAD button to upload the image.....
Inorder to insert an image according to the employee number in the table, for that how i can modify the above page process inorder to upload the image in my table with the corresponding employee number in the table.....
As i was confused with the above page process because the above process is referencing the apex_application_files table for the blob...
That is creating confusion for me inorder to alter the above page process....
Can you friends, help me with the page process alteration......
Thanks

Hi vee,
Thanks soon after the alteration according to the page process given by you i can able to insert a new image corresponding to an employee_number..
But vee, in my table i have taken employee_number has a primary key column as i doesnt allow duplication......so for that i have altered the page process to the below......
declare
l_count number(25);
begin
select count(*) into l_count
from a_images2
where employee_number = :P2_EMPLOYEE_NUMBER;
if l_count = 0 and :P2_BLOB_CONTENT IS NOT NULL
THEN
INSERT INTO A_IMAGES2 (EMPLOYEE_NUMBER, FILE_NAME, BLOB_CONTENT, MIME_TYPE)
SELECT :APP_USER,FILENAME, BLOB_CONTENT, MIME_TYPE
FROM APEX_APPLICATION_FILES WHERE NAME = :P2_BLOB_CONTENT;
DELETE FROM APEX_APPLICATION_FILES WHERE NAME = :P2_BLOB_CONTENT;
elsif
l_count=1 and :P2_BLOB_CONTENT IS NOT NULL
then
update a_images2
set BLOB_CONTENT=:P2_BLOB_CONTENT
where employee_number=:P2_EMPLOYEE_NUMBER;
END IF;
COMMIT;
END;so, for what logic i have framed the above process means,
Suppose if a employee wants to upload his photo for the first time means, he needs to insert newly into the table....For that i performed insertion into the table in the above query......If an employee needs to update his photo means, he needs to update for that i used update statement in the above query.......
I guess there is no any mistake in my above page process..........
if i tried to update a photo using the above page process query means, it is returning the error like........
ORA-01465: invalid hex numberi couldnt guess what might be the issue over here....
Whether my above page process logic is right, vee............
incase any mistakes, point it out vee.......
Thanks
Mini...
