Fantastic, I've been looking for something to do this exact same thing.
READ_IMAGE_FILE problems ...
Vladas, June 04, 2003 - 7:02 am UTC
I found one, but very bad thing, if in Oracle form I use READ_IMAGE_FILE for image insert in the table (in example foto.jpg and I don't use any compressions for this image item in my form, the Image format is JFIF) and later try to see this image, the image quality is badly than original my image. If I use BMP type of Image format the image quality is such as original but the image size too big. If I understood correctly the Oracle Forms READ_IMAGE_FILE function use some compression :(.
May be somebody know how insert image in JPEG format from Oracle forms and local PC to BLOB field in the server with image quality such as original.
Image retrieval using forms ver. 6.0
Archie Magnaye, June 24, 2003 - 9:39 pm UTC
The article came in very handy. But suppose I'd like to print that particular image, using reports ver 6.0, how do i retrieve the image from the image_table and print it on screen or on paper? Thank you and hope to hear for your prompt response..

sorry, haven't used forms since 1995 myself.
try otn.oracle.com -> discussion forums, lots of forms developers out there who have probably done this (or at least tried)
How to load and display images from database
Yong, June 25, 2003 - 5:12 pm UTC
Here is my way to do so
CREATE TABLE IMAGES
IMAGE_NAME VARCHAR2(30) primary key,
CREATE OR REPLACE PACKAGE BODY IMAGE AS
PROCEDURE load(filename VARCHAR2) AS
dot_pos := INSTR(filename,'.');
image_name := filename; --SUBSTR(filename,1,dot_pos-1);
mime_type := 'image/'||SUBSTR( filename,dot_pos+1,length(filename) );
INSERT INTO images values(image_name,mime_type,empty_blob() )
RETURN content INTO b_lob;
f_lob := BFILENAME('SOURCE_DIR',filename);
PROCEDURE get(name varchar2) AS
exception when others then
htp.p(sqlcode || sqlerrm);
SQL> create directory source_dir as '/mydir';
if you have an image file in /mydir/toolbar.gif
SQL> exec image.load('toolbar.gif');
create procedure test as

I have stores image in
e_id varchar2 (12);
e_salary contain a 'image item'
so that when some one enters
employee id it will display his/her picture .
How I can do that using form 6i?
July 19, 2004 - 8:00 am UTC
i haven't used forms since 1995 -- suggest you try otn.oracle.com, there are discussion forums there and one of them is centered around forms/developer
A reader, July 19, 2004 - 10:02 am UTC
Once the image is loaded, Oracle will query and display the image on the form. You don't have to do anything else. Try it out..
can you help
oracle, July 21, 2004 - 2:22 am UTC
"a reader' can you give a example.
It will be very helpful for me .

they are saying "create default block on table, it'll just happen"
Different blob format?
Alex, February 16, 2006 - 9:18 am UTC
I have about 2000 images in database (8.1.7) stored through forms application. I can see them in forms applications, and download them using pl/sql as well. But, I can not see them using java swing client (application build using bc4j, JDeveloper). However, images uploaded using java swing client are visible by both: forms and java swing.
Is there something specific with blobs and forms?
February 16, 2006 - 12:10 pm UTC
define what you mean by "not see them", they are just data in the database?
A reader, February 16, 2006 - 11:13 pm UTC
Its such a same after numerous postings by Tom mentioning error message or a small demo still people dont get it, too many post mentioning "does not work" :-(
blobs, forms, jdeveloper
Alex, February 17, 2006 - 3:57 am UTC
Well, I start to believe that blobs are not just data in database :)
Gifs are stored in blob column through Forms application. Fields in this column are not empty, I can see that using pl/sql (blob fields could be exported in regular gif files through PL/SQL Developer for example), and I can display them through Forms application.
I have problem with displaying gifs in java/swing application. To display gifs I use JUImageControl, and it doesn't work with ones stored by Forms application. If I use JTextField instead of JUImageControl, I can see that bc4j returns data (not very meaningful character/byte array representing contents of a gif file).
If the very same files are stored through java/swing client they are visible in both swing and forms application.
In thread </code> http://forums.oracle.com/forums/thread.jspa?messageID=801811
<code>I saw that the reason for irregular blob behaviour could be its "forms background".
What is exactly problem?
Is it possible to update blob column in database somehow (reloading over 2000 gifs will be pretty uncomfortable and slow) ?
I am using JDev 220.127.116.11 build 1605, DB 8.1.7., Forms 6i.
February 17, 2006 - 1:46 pm UTC
I have no idea what JUImageControl is or does, sorry.
blobs stored through forms are different than ones stored through Java
Alex, February 24, 2006 - 2:36 am UTC
Surprise! Forms uses compression (apparantly unhandled by JUImageControl) when storing gif files into blobs. That way, same gifs are not same blobs if they are stored through Forms and Java/swing client. More about possible workaround would be soon on metalink.
DISPLAYING JPG FILE STORE IN THE DATABASE ON FORMS
Jim, December 18, 2006 - 5:08 pm UTC
I have loaded various images into the database.
Normally I can just goto the block and execute the query and the image (blob) field will appear.
There are various JPG files that do not show up and no error is given. The orginal jpg files that seem to cause the problem are from digital camera. The file has lots of extra infon on it (camera type, f-stop, iso, etc). If I take the same image and load it up in Microsoft photo editor and then re-save it (changing nothing) it loads and displays just fine.
The end users do not have time to re-save every image they wish to load into the database.
I am running: Forms Version 18.104.22.168.0
Oracle9i Enterprise Edition Release 22.214.171.124.0 - 64bit Production
With the OLAP and Oracle Data Mining options
JServer Release 126.96.36.199.0 - Production
December 18, 2006 - 7:11 pm UTC
you can use the forums on otn.oracle.com for forms - I haven't used it in over ten years.

Displaying BLOBS on Oracle Forms
Frank T, November 06, 2007 - 10:13 am UTC
Our DBA has an oracle table with BLOB/image column, however, the BLOB/image column is defined as ORDIMAGE data type. I am trying to display this BLOB/image on my Form data block item of type Image.
I have queried the table blob/image column within the when-button-pressed and have the blob/image readily available in variable of type ORDIMAGE as defined in the database, but I am wondering if I can use "Read_Image_File" or some other built-in function to display this on my Form. Your assistance in this is greatly appreciated, Tom. Frank
P.S. I am using Forms 10.1.2 and Oracle Database 10.2

query to save image into db

storing documents in the database
Boris, March 12, 2012 - 4:33 pm UTC
I have been asked to design the best way to manage the documents for one of our business requirements.
As per your suggestion , I will go for secure LOB to store the ocuments in the database itself rather than storing the documents in the file system, but I am a bit confused about storage and retrieval of the file from the database.
I have a table called doc_detail with the following details
create table doc_detail
document_id number primary key, -- system generated key
document_type varchar2(10) not null, -- doc,pdf,xls
document_content blob not null
lob(document_content) store as securefile slob
1 doc test.doc
2 pdf test.pdf
DB version :Oracle 11g Release 1
My queries are
1. How to load the above doc,pdf files into the oracle database without using sql loader?
2. What is the best way to do capacity planning for these documents. Let's say the average size of each file is 50k max.
3. How to download the data from the table with proper format? I heard that we can not download the documents from database without java interface. Is that true?
4. Are there significant overhead in storing the file in the database?
Could you please shed me some lights on this? It would be great if you give an example, if possible.
Thanks for excellent service to oracle community.
March 13, 2012 - 7:33 am UTC
what programming environment are you using? If you used something as simple as APEX, you wouldn't even have to create a table (we already have one for documents) and the file upload is rather trivial, you just include a button basically.
as for capacity planning - you'd have to tell us how many documents you plan on having over what period of time. Then, for storage capacity, we just multiply.
you can download documents easily - for example, click on the files tab on this page (upper right) and click on a link and start downloading files. You want to know how many lines of java code that took? Zero. In fact, it took pretty much zero lines of code - it is built in with APEX ( http://apex.oracle.com/
to test drive it, you already own it, it comes with every Oracle database)
there are no overheads as far as I'm concerned, only benefits to storing it in the database - like backup, recovery, universal access (what happens if you decide to have more than one app server and you were using file systems?), security, integrity, searchability and so on.
