How to display a blob??

i have a table with a column as a blob (pic file), is there a way to get the blob to display, without having to use the content area...
i've tried reports but blobs are not supported...
thanks

You can build a Form component to insert/upload, query, and open a file as a BLOB and/or leverage the PL/SQL Gateway features within Oracle9iAS. See: http://technet.oracle.com/docs/products/ias/doc_library/ias102/comm.102/a86263/feature.htm#1004906

MAX: How to display icons (blob) in VB

Hi!
I've written a VB application which gets some information from MAX. It works very well, but I was wondering how to display the icons (stored as blob). Who can help me? Thank you in advance!!
here is a piece of my code:
Dim maxConf As mxConfiguration
Dim maxItems As mxItems
Dim maxItemAttribute As ImxItemAttribute
Set maxConf = New MXCTRLLib.mxConfiguration
maxConf.Initialize ("Local")
Set maxItems = maxConf.EnumItems("CAT=Software,ALL")
Set maxItemAttribute = maxItems.Item(ItemsListBox.ListIndex).EnumItemAttributes.Item(AttributesListBox.ListIndex)
Select Case maxItemAttribute.AttributeType
Case "Blob"
'here, I want to display the icon and I need your help!
Case Else
ListBox1.AddItem (maxItemAttribute.AttributeValue)
end select

I will try this when I get back home - travelling at the moment.
A bit more background....... I have a Function that is called to produce a yearly calendar view of rentals for a home, along with the rental prices - this has already been written using the as_pdf3 package, which can either physically create the report on the server (using utl_file), or it can return the blob direct.
On the screen, the user can select the years that they wish to see in the report, push a button which will pass the parameters into the above said function, and then launch the "blob" in another window (as the blob is PDF format, it would launch the users PDF reader) - if the user then wants to save the report, they can do (using PDF reader) - this avoids me a) saving and housekeeping a file(s) on the server, b) I don't have to enable utl_file for the schema

How to display a BLOB (Image) in a EBS Report?

User requested to add a Logo image to a report which is called from E-Business Suite (EBS).
The image is currently stores in a BLOB column.
How can I make the image to display on the report?
Thanks!

I was trying to use the BLOB and display the image in a report.
Per your suggestion:
"Select the column in your query.
Create an item in the layout editor and set the source to this column.
Set File Format to Image."
My question was I dont know how to "set the source to this column" as you described above.
So, to work around it, I moved the image file phyically to the UNIX file system.
Then, created an item in the layout editor which required a valid "image file path" the property palette.
Since, the report was created under windows, it did not validate with UNIX file path.
That's why i need to perform extra steps to get the file path correct to work in UNIX.
EDIT:
I guess when you said "set the source to this column", you mean to map the "Field source" attribute in the property palette to the database column from query.
But depends on what item you want me to create (I created a "Link File" item) and it does not have the "Field source" attribute available to map to a database column.

How to display a blob as an image

I am working on an application which stores images in a database as blobs. I need to extract these images and display them from a web page. How do I go about this using JSP or JSF?
Werner

Thanks for the quick response, matlas. I should have included more info in my original post. I am familiar with reading/writing blobs from the database. The part I am stuck on is how does the java servlet return the blob (dPhoto below), to the web page?
i.e. from <img src="employeePhoto.jsp&empId=123">
ImageIcon dPhoto = null;
// open connection
Connection photoConnection = startup.openSQLConnection(SQLDriver, SQLConnectionString);
// setup select string
String sqlStatement = "select Binary_Photo from employeephoto where Employee_ID = '"+employeeID+"'";
try {
// perform select
ResultSet rs = photoConnection.createStatement().executeQuery(sqlStatement);
// if record found process blob
if (rs.next()) {
// get blob
Blob image = rs.getBlob("Binary_Photo");
// setup the streams to process blob
InputStream input = image.getBinaryStream();
ByteArrayOutputStream output = new ByteArrayOutputStream();
// set read buffer size
byte[] rb = new byte[1024];
int ch = 0;
// process blob
while ((ch=input.read(rb)) != -1) {
output.write(rb, 0, ch);
// transfer to byte buffer
byte[] b = output.toByteArray();
input.close();
output.close();
// load final buffer to image icon
dPhoto = new ImageIcon(b);
catch (Exception exc) {/ do your exception processing}
// close connection
startup.closeSQLConnection(photoConnection);
// dPhoto holds image or is null at this point.

SOLUTION - How to display a BLOB content in Portal Report

Courtesy of Kelly Wong:
1. Every time a record of the file information is inserted into the
PORTAL30.WWDOC_DOCUMENT table while you inserted a record to the blob
field in a portal form that you created.
[The fact that a file uploaded appears in the WWDOC_DOCUMENT table is actually a side-effect of Forms file upload, this may change in a future version. However this example gives a pretty good solution to the problem - Dmitry]
2. If you describe the PORTAL30.WWDOC_DOCUMENT table, you will find
that a few of the columns are: NAME, FILENAME, MIME_TYPE, BLOB_CONTENT,
CREATOR, etc.
3. I created a pl/sql procedure that takes a NAME parameter.
The code of the procedure is as follows:
CREATE OR REPLACE Procedure get_url
(V_FILENAME IN VARCHAR2)
IS
url varchar2(100);
BEGIN
url := '/pls/portal30/docs/'| |v_filename;
portal30.wwv_redirect.url(p_url =>url);
END;
4. I then created a portal report, select NAME, FILENAME, MIMETYPE,
CREATOR fields from PORTAL30.WWDOC_DOCUMENT. (remember, no BLOB_CONTENT
field is selected!) My select statement is:
SELECT '<A
HREF="scott.get_url?v_filename='| |name| |'">'| |filename| |'</A>' filename,
name,mime_type,creator
from portal30.wwdoc_document
where creator = 'KELLY'
You can see that I am passing in "NAME" instead of "FILENAME" into the
get_url procedure because the it needs the "NAME" info to display the
file.
Actually, the content in the NAME column is something like:"563.TXT",
and the content in the FILENAME column is "F15675/IPORTAL_LOCAL.TXT".
The hyperlink can be either on the NAME or FILENAME field, as long as
you pass in the content of "NAME" into the procedure.
And it should be fairly easily to substring the FILENAME to show only
"IPORTAL_LOCAL.TXT" if the client doesn't like to see the number
portion.
That is, when I click on the link, I am able to see my file in a new
browser window.The only drawback in this scenario is if there is a link
from your document to a portal component (form/report), it may not link
to the form/report. If there are links in the document link to other
document (html, txt, etc.), it will be no problem. It just open the
document in another browser window.
Please feel free to give me any comment on this and post it to the forum
if needed. I just don't want to search for the original questions in
the forum and attach the reply to it.
Regards;
Kelly.

Is this method working also for portal 3.0.9?
I can't get it to work.
Is there a way do put a link to download the content of a blob field inside a report in version 3.0.9 that comes with iAS 1.0.2.2?
Thank's in advance

How to display clob/blob in the web layout using Reports9i

Hi,
I've created a report that selects both a clob and blob datatype in the query. However, when I run the report using the 'Run Web Layout' tool no data is displayed for these columns. Does the <rw:field> tag support such datatypes ?.
Regards,
Chris

Hi Chris,
Reports9i supports both BLOB and CLOB in both paper as well as web layout. Pl make sure that in the column properties that you want to display, you have selected the "File Format" correctly (to do this, go to data model > column > property inspector > file format). Eg, you can select "text", "image" etc depending on what you have stored in the column. Also, when you want to display an image in the web layout, you will have to write containsHtml="yes" inside your <re:field> tag.

How to display a blob in a new window (without saving as file)

Hi,
I have been using the excellent as_pdf3 PLSql utility to create a pdf at run time. The result works great if I save the blob to file, however, I don't want to clutter up the "server", so I would like to send the blob down to the user by opening a new window (pdf reader) and then give the user the option to save where they wish.
I am running Apex 4.1.1, Oracle 11GXE with Apex Listener under Glassfish opensource on Ubuntu Server 11.2.
I've hunted left right and centre, and either I've not got the correct combination of words in the search, or the question has never been raised.
Can anyone give me some pointers and/or code to assist ?

I will try this when I get back home - travelling at the moment.

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:

How to display image using Carousel in ADF using BLOB column DB

Hello everyone ,
I tried creating a Carousel component in ADF do display an image , but it seems to be not working .
This is what i tried .
1 ) Created an empty page .
2) From data control drag and drop view object ( one of the column in DB is blob which saves the image ) as Carousel .
3 ) Drag and drop the image over Carousel component ,
Now what should be the source for the image ?? from expression builderi tried giving #{item.Image} images are not picking up .
Could you please advice .
--Keerthi

Keerthi,
You cannot display a BLOB as image as it is. You need to convert them to display in your UI.
Check out this blog on how to use a servlet to convert the blob into image and display in the page.
