Images in the database

hi friends,
please help me with sql statements to insert a image into a database using blob or longraw datatype.
suppose i have a image in c:\images\image.jpg.
thanks in advance.
Mohan.

Hi Mohan Kumar,
Did you try inserting an
image using any frontend such
as Java?
Will get back to you if I get
anything concrete on your
problem.

Is it better to store the image in the database or to use BFile

Hi all,
I've a doubt regarding the handling of the image. For example i've the images of the persons amounting to 50,000(the number will be increased in future). So i just want to know which is the better menthod. is it better to store all the images in the database or to store in local OS and use Bfile concept. I'm using Forms 6i and Forms 10g(10.1.2.0.2). OS: Windows XP

But the total number (i.e.., 50,000) is scaring me to use the BlobI don't think the database will cause problem just due to the amount of data stored in blobs. Of coure you would have to check which parameters to set for the blobs to make storage efficient. If
You didn't mention your db-version, in 11G you could also think of using compression and deduplication to deal with the data amount.
In general i agree with Francois, the best way depends, but in terms of data consistency and easy backup/restore there might be some advantages in using the blob-version.
hope this helps.

How do i store and fetch image from the Database(Access)

i am facing one problem in inserting the image into the database.the steps i followed as
1)i have created one database(access) as "Image" and into that one table as "Image" and field as "image"
type of the field is ole object.
2)i have inserted one image into the image field through "database.vi"
3)now i am trying to get the image from the database by "Fetching Example.vi"
4)it will succesfully retrieve the image from that field .
5)but when i close the both programs and reopen those that time i am unable to get retrieve the image.

I would like to suggest different approach for saving the images in the database.
I was working on Medical Imaging Company. The way we save the images in real-time was by writing the name and path of the images to database.
The images themselves where saved directly to disk.
I don�t think that access is very good in taking care of GBytes of data.
It happens some time that the database gets damage. If you have the images separately you can create fix procedure. (We had one).
Good Lack,

Storing images inside the database

hi,
we are running oracle 9ir2 on Solaris and would like to know how to go about achiving the following:
would like to be able to read/write/create/delete bitmap image files in a file share on the same server as the database which would be stored in a table within our schema in the form <filename varchar2>,<image-file-contents blob>
Is this possible?! If so - any pointers in the right direction would be great!
thanks,
p

To some extent, this was covered a few days ago in the PL/SQL forum. There are some examples of uploading image files to blobs in the database here.
upload any file (like .DOC,.JDG) to oracle database?
If you want the images to be visible on a file system, you may want to use BFILE's, rather than BLOB's. BFILE's are essentially pointers in the database to file system objects, while BLOB's are stored completely in the database. The major disadvantages of BFILE's are that
- the file may be deleted or moved, leaving the Oracle BFILE pointing at nothing
- the file won't be backed up with the rest of the database
Going up a level of sophistication, you could store the images using interMedia. This gives you significantly more options for manipulating the images within the database.
Finally, you can use Oracle iFS (or whatever it's been renamed to today) to provide a file system interface to an Oracle database. This is the most robust of the options, but is also the most work to configure.

Can BI Publisher read the images from the Database?

Hi All,
Can BI Publisher read the images from the Database?
if yes how it can be achieved?
Thanks
Aravind

Hi,
There is an example in oracle db. Use the schema PM (Print Media).
Select the corresponding table that contains the column AD_PHOTO.
In your RTF template simply to print the image stored in the db use:
<fo:instream-foreign-object content-type="image/jpg"> <xsl:value-of select="AD_PHOTO"/>
</fo:instream-foreign-object>
RUn the RTF template and it should show you all.
Cheers

Loading an Image from the database and display it on browser

I do not know if this is even possible.
At the moment, to load an image inside an Html page you need to use the <img src=""> tag. and in the src you put the path of the image. Now I would like to save an image inside the database.
An option to still display the image on the browser would be that my service object, would load the object from the database (saved as blob) then save it somewhere on the Server, and the still use the <img> tag to load the image from that location.
However I was wondering wheather there is another way to do it without saving this image on the server. that is loading the bytes from the database (or a location on the server) and provided these bytes to the jsp page to display the image.
Is this possible? or?
regards,
sim085

hmm ... ok .. that sounds good .. but that means that
a servlet must exsist at all time to display the
required image.Servlets are usually instantiated by the servlet container upon an incoming request.

Uploading of image to the database?

Display Image from the database but prevent it from refreshing on every pages

Hi there,
I can see there are many discussions around this but my query is slightly different. I'm writing this on behalf of one of my developers. (sorry for my ignorance on techie stuff.. :-))
A logo is being displayed on a few pages, which is called from the database. However, the problem is that - this logo refreshes every time when you traverse to each page causing a performance issue or sometimes slow loading of the image.
My question is - how do we stop it from loading on each page from the database?. I would rather load once when the main page loads initially and then maintain this on other pages too.
We can keep this logo on a file system (FS) and display it via CSS/HTML/frame but since we want to keep it flexible/dynamic where a user can upload a new one whenever it changes and hence DB seems to be the suitable option (in my opinion).
Can someone please help?
If you need any further info around the coding how it is being done at present, pls let me know.
Thank you

read this http://docs.oracle.com/cd/B28359_01/appdev.111/b28393/adlob_tables.htm#g1017777
you can cache lobs in the database too
you can also upload the pic in your file system using utl_file package and then put the image in the working directory mentioned in i.war
you can then reference the image and it will not be stored in the database and will be cached

Reference images outside the database

Hi,
I tried to return html content from a pl/sql procedure but the images referenced were missing. Attached please see the part of the coding in the pl/sql procedure. Everything worked except the images. When I specified something like <img src="" />, the image would come up. Whenever I included an inline (or external) stylesheet in the pl/sql procedure, the images were not picked up.
Thanks.

Please help to load image in the database

Hi to all. ....
I need to save image file in the database thru forms ...
I have some image file in the application server and I need to load it in the database in a Blob col..
Any help ... ??
Thank's in advance

Hi!
Your forms version is very important.
If you use forms 10g and you want to load the image on the client, you need webutil.
If you use forms 6 or you want to load the image from the application server to
a image item in your form, you can use the read_image_file forms build-in:
read_image_file ( 'x:\path\image.jpg.', 'JPG', 'block.image_item' );On forms 10g this will be executed on the server and the filename and path has to be
a physical place on your servers harddisk.
The image item has to be an item of type image and must be assinged to a blob colum in your table.

How to upload files/images to the database from a form.

I'm making a custom user profile form.
The users can update their profile in this form.
I cannot use the standard profile form, because the customer got very specific
demands about the context of the profile form.
In this custom profile form the user must be able to upload an image
from their hard disk(just like in the standard profile form).
I've got the following questions about uploading pictures:
- How do I make a button to show the explorer window.
- how do I get the chooses file-name in a field.
- how do I get the new file in the database.
- how do I get rid of an old file in the database.
- how do I get the image on the form.
Or is there a special portal way to upload images/files in a form.
Does anyone have a clue?
regards
arny

Hi,
Regular Portal forms will support upload of images/documents to the database. Just identify your column as a blob, and the 'Browse' button will automatically show up in the form and the users will get to choose the file they want to upload from their desktop.
The thing is, I haven't been able to figure out how to get that document/image back out of the database (e.g. in a report), once it's put in. Maybe someone else can answer that.

Loading an Image to the Database

Hello
I have a requirement to load 1000's of images to a database.
In the pass we have successfully loaded images from a screen using
select blob_content, id into image, apex_id from apex_application_files where name = :P120_LOAD for update;
I now tried to use apex_application_file to do the same in a background PL/SQL procedure
COMPANY_ID_FILE:= 'E:\' || COMAPANY_ID || '.jpg';
select blob_content, id into image, apex_id from apex_application_files where name = COMPANY_ID_FILE for update;
This does not seam to work!?
I believe apex_application_files is not the right function to used in this case
Any comments or recommendation very welcome
Thanks

Hello
I pleased to report it is all working now.
My thanks to the people above, Harm ten Hapel from Oracle support and the link below
http://www.psoug.org/reference/dbms_lob.html
This is what I did:
Created a directory within Oracle which linked the directory on the Oracle server. It does not create a directory on the server. This need to done manually.
create directory data as 'c:\data';
To show that you created the directory correctly
select directory_path from all_directories;
To delete a directory
drop directory data;
The code I used is
begin
TEMP:= data ||'.jpg'; -- file name on the server
dbms_lob.createtemporary(l_blob,true); -- initialise the Blob field
l_bfile := BFILENAME('HOTEL',TEMP); -- Assigns file
DBMS_LOB.fileopen (l_bfile, DBMS_LOB.file_readonly); -- open file
lgh_file := dbms_lob.getlength(l_bfile); -- collects file length
dbms_lob.loadfromfile(l_blob, l_bfile, lgh_file); -- reads file
DBMS_LOB.fileclose (l_bfile); -- closes file
--- Extracts the information about the blob data
DBMS_LOB.CREATETEMPORARY(attributes, TRUE, DBMS_LOB.CALL);
ORDSYS.ORDImage.getProperties(l_blob,
attributes,
img_mimeType,
img_width,
img_height,
fileFormat,
compressionFormat,
contentFormat,
img_contentLength);
image:= l_blob;
RECORD_FOUND:= 0;
--- This is important as the system will only let you open a small number of file at open. If the file open fails it still counts as an open file and find the load programming failing with too many file open error
EXCEPTION
WHEN OTHERS THEN -- catches all 'no data found' errors
DBMS_OUTPUT.PUT_LINE('DATA_FOUND - file = ' || TEMP);
DBMS_LOB.fileclose (l_bfile);
record_found:= 1;
end;
I hope it is of help
Thanks to all

Hi, I'd like to display a dynamic image from the web inside a JLabel or any other swing component it could work in. I've been looking on the Swing tutorials and others forums, all I can have is that a JLabel can load an Icon object, defined by an image URL, but can this URL be like "http://xxxxx/image.jpg" somehow or can it only be a local image URL?>
I do not know why you start talking about an image on the web then go on to show concerns about whether it will work for a 'local' URL.
But perhaps this answer will cover the possibilities.
So long as you can from an URL to the image, and the bytes are available for download (e.g. some web sites wrap a direct call to an image in HTML that embeds the image), the URL based icon constructors will successfully load it.
It does not matter if that URL points to
- a web site,
- a local server ('localhost'),
- an URL representation of a File on the local file system, or
- it is inside a Jar file that is on the application's run-time classpath.
How you go about forming a valid URL to a 'local resources' (or indeed what you regard as local resources) is another matter, depending on the form of the project, and how the resources are stored (see list above).
Probably the main reason that examples use images at a hard coded URL on the net is that it makes an 'image example' self contained. As soon as we compile and run it, we can see the result. I have posted a few examples like that on these forums.

Displaying images from the database.

Hi,
I use standard portal forms in the locally built provider area to upload images into a blob field in a table. Then a dynamic page to output the image onto the screen.
I use the following code. This works for all images on our old system. db version 10.1.0.4 and apps server version 9.0.4.2. Installed on a windows machine.
This code also works for gif images on our new system. DB version 10.1.0.5 and apps server version 10.1.4. Installed on a Linux machine. But it does not work for jpg images.
Has anyone got any ideas?
Thanks,
Michelle
