Displaying image from BLOB from DB in Browser

I have a PL/SQL procedure to create a table with a BLOB image, mime type, key, etc. I can use another PL/SQL to load the images into the table. I have a PL/SQL procedure to get an image. I would like to call this procedure and pass the key parameter to display an image in a browser using HTML. Does anyone know how to do this?
Thanks.

Use a java servlet to call your stored procedure (using jdbc), this will return the image as a java blob class. You can then write the java blob bytestream to the servlet response object, this should then appear in the browser.

 <IMAGE_NAME>mlish</IMAGE_NAME>
 <IMAGE>Lots of characters that represents the BLOB</IMAGE>

Flex can create an AIR application.
But a swf file can't read from the local drive.

Apex 4.0 display image item :BLOB column returned by SQL statement

Hello
I'm creating an display image item in apex 4.0. The source is a BLOB column returned by SQL statement.
When I'm issuing an sql statement like this:
   select lado.blob_content
   from   large_documents      lado
   ,        large_doc_headers    ladh
   where lado.ladh_nr = ladh.nr
   more criteriait works fine.
When I create a function inside a package with the same query (in a cursor)
function get_image(some parameters in) return blob
Following in apex by:
select get_image(some parameters) from dualI get a
ORA-06502: PL/SQL: numeric or value error: character string buffer too smallAnybody any idea why this does not work?
Regards Erik

Hi Eric,
the environment assumes varchar2-output by default, which will be limited to 32767 characters and may have problems with binary formats. You could define a blob-variable to select the value into.
DECLARE
l_blob BLOB;
BEGIN
SELECT get_image(some parameters)
    INTO l_blob
    FROM dual;
END;
/If you expect the BLOB-Content to be text (you should consider CLOB then), you may use UTL_RAW.CAST_TO_VARCHAR2 to convert the content. If your object is larger than the maximum varchar2 size, or you want to convert BLOB to CLOB, you might be interested in some converter like described here: {message:id=559749}
Hope this is what you were searching for.

Displaying image in BLOB via pl/sql cartridge

Hi gurus ,
I have a oracle web site. I am dynamically putting links in the page using pl/sql cartridge and procedures. I have loaded all my pictures for the catalog in the BLOB columns. Can anyone help me or direct me how to display these images using plsql cartridge dynamically from BLOB columns instead of from image files ???

Since this is the interMedia forum my suggestion would be to store the image data in an ORDImage column and use the interMedia WebAgent to retrieve the data.
The interMedia WebAgent can be used with "naked" blobs but you'll need to code your own pl/sql routines (the code wizard won't do it for you).
The code wizard does generate procedures for OrdImages but due to some reasons the GET_XX procedures don't work and give the error "ORA-04043 Object Get_Image does not Exist "

Display image file - BLOB on Report

Hello there,
Has anyone knew how to display an image file (BLOB) on Report using Application Express?
You prompt reply would be appreciated.

Once htmldb.oracle.com is available again, you may have a look in my demo application:

In the tab section II, you will find an image display example and the corresponding

Can't display image on TV from MacBookPro (using DVI to video adaptor)

I purchased the apple "DVI to Video Adapter" to be able to use my TV as a display, but it isn't working despite help from the Apple help desk.
I'm using a standard TV video cable that plugs into the yellow video input jack, with is a Hitachi full multi-system C2578FS that works anywhere in the world. Before my iBook died last year, I used to watch movies from it on the same television using a similar setup (just VGA instead of DVI adaptor).
The television is not receiving the signal in any way. My MacBookPro is: the 'detect displays' when activated in my MacBook Pro's menu bar shows a display it calls "NTSC/PAL" which is the television, and I've tried each of the different settings to no avail.
Any ideas on how I might finally watch a movie or slideshow on my television?
Kind regards in advance,
-ck-

After much fiddling with display resolutions and TV setting, and several calls to Apple help, problem was found to have a really basic solution: replace the RCA connector cable. The old one was shot.

Display image in Report from File Server

Hi
As the logo of the company is changing every 3 - 4 months, i need a solution for this..
my approach is to replace the new logo in file server
call the logo in the oracle reports... using oracle reports 6i...
but i am not able to do so ( which objects to be used like formula column, link file, ole) ... any help from your side will be good.
Regards
Yram

You may put the logo into db as a blob column and retrieve it onto report. One update in db would update all calling reports.

Detecting and displaying images inside SWF from same web page its embedded in

Great forum and appreciate the great help I've been getting
here. I am getting a bit more used to Flex now - the collection of
controls is pretty amazing.
I am trying to create an ImabeBrowse.SWF which when embedded
on a web page, it would then automatically show thumbnails of all
the images from that same page. Has anyone done anything like this
in AS3?
From documentation, it sounds like I would need to write some
Javascript which would traverse the HTML's DOM to get all image
URL's, and then pass these into the SWF?
If one of you experts could share some code, that'd be
greatly appreciated!!

Asking for more.........
Yes, I do agree there is no need to create an additional DAD when we want to call a procedure from infrastructure database (iasdb) because giving grant to public or portal_public schema is enough.
But why is it that even after following the right way to create a DAD for HR schema in infrastucture database fails to call a procedure?
The error which I get is:-
Database Log In Failed
TNS is unable to connect to destination. Invalid TNS address supplied or destination is not listening. This error can also occur because of underlying network transport problems.
Verify that the TNS name in the connectstring entry of the DAD for this URL is valid and the database listener is running.
The details for rajhr DAD
Database Connectivity Information
Database Username : HR
Database Password : hr
Databse Connection String : <blank>
I have left database connection string blank as the infrastructure database is local.
Is it that I cannot have two DAD for a local database eventhough they point to two different users?

BlackBerry NOT displaying images which are from an SSI

Hi all - hoping someone knows the answer to the following, or where I may be able to go to get the answer.
I'm working on a website that has SSI (Server Side Includes) and CSS.....we have an SSI for the header, footer, and navigation sections of the site, and some of our images are referenced within the CSS. Our BlackBerry is configured to read CSS as a handheld, but it doesn't seem to understand how to pull in an image which is referenced within an SSI or CSS.......is there another oprion/setting/download that we need in order for it to display the images?
Thanks for any info you can provide!

How to display image in blob field in ResultSet in SiteStudio?

I am running Site Studio 10gR4. For a custom page, I created a component that basically runs a query. The structure of the underlying data is a combination of Varchar2, Date and a single BLOB field. The blob field either contains a simple jpeg image, or nothing.
In my Page where I am looping through the data, how do I display the blob as an image?
Currently the code looks like this:
 
 <tr>
 <td></td>
 <td></td>
 <td></td>
 <td></td>
 <td></td>
 <td></td>
 <td></td>
 </tr>
 Field 1 is a blob and fields 5 and 6 are dates.
So really two questions:
1. How do I display field1 as an image?
Example:
doesn't do it. Is there a different function then getValue() that I should be using to get the blob contents?
2. I want to compare the date fields to todays date, and either change the color or conditionally display the fields. I could do this with basic taglibs from jsp. How do I do this with IDocScript?
Example:


Thanks, Ken

I actually don't know the answer to #1. If I were to guess, there's nothing out-of-the-box to handle blobs, so your best option is to write your own idoc function. Take a look at the How To component if you don't know how.
For #2, you almost have it right. Insert bold:

Display image for BLOB Download link in Interactive Report

I have a table containing BLOB data and am displaying the table in an interactive report. I would like to replace the "Download" text link with an icon that represents the MIME type of the BLOB, but can't seem to find a way to make the substitution. Does anyone know how to do this? Thanks.
-Jeff

Hey Ben,
Thanks for the suggestion. I understand what you are saying, the problem is that when you have an interactive report that includes a BLOB and you use the built-in method for displaying a download link, it only gives you the option of using a text link. The method is outlined in the online help under:
Home > Advanced Programming Techniques> About BLOB Support in Forms and Reports > About BLOB Support in Reports
This is done by using the following syntax in the Number/Date Format of the column attribute of the BLOB:
DOWNLOAD:CC_DOCUMENTS:CONTENTS:ID::MIME_TYPE:FILENAME:UPDATED_ON::attachment:View
Where the last parameter is the link text. The only problem is that there is no option for substituting an image rather than the link text. That's what I'm trying to work around. Sorry if you new all of this already, but I wanted to explain what I've already done. Thanks for any help you can offer.
