It depends on what you use as a front end for uploading your images.
Oracle Forms has a certain way of doing this, while Application Express has a totally different approach. You can even upload your images using SQLDeveloper

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 load images from BLOB to javascript?

hi, Guys:
I need to load thumbnail images from BLOB to multiple markers' infowindow in Google map . I have implemented Google map in APEX. I load the data suchas text for every marker's infowindow from Oracle database table with PL/JSON, and infowindow works fine. Could anyone give me a suggestion or example so I know how to load images to javascript?
Thanks a lot.
Database: Oracle 11g R2
APEX: APEX 4.1
Thanks.

hi, VC:
Thanks for your kind reply. I need to render these images out of APEX session, actually in javascript that is related to Google map markers' infowindow.
I checked the documents of APEX_UTIL.GET_BLOB_FILE_SRC, but my impression is I need to use it in APEX instead of javascript if my understanding is correct. I already implemented a procedure with PL/SQL to load images from a BLOB column in Oracle database. But the problem is, how can I pass it to javascript code out of APEX to javascript (I could pass text or number from APEX to javascript with PL/JSON though,But I assume that still google map will be within a valid apex session? if so you should be able to use the above api.
Basically what this api does is generates a kind of url to each blob in the database, not sure how google api's deal with this though. Why don't you give it a try?
The other option is to make your pl/sql procedure public and then you can generate the json to include the images urls such as:
     "employees" : [{
               "firstName" : "John",
               "lastName" : "Doe",
               "imgSrc" : "http://somewhere/db_schema.your_download_proc?p_file=#ID#",
               "firstName" : "Anna",
               "lastName" : "Smith"
               "imgSrc" : "http://somewhere/db_schema.your_download_proc?p_file=#ID#",
               "firstName" : "Peter",
               "lastName" : "Jones"
               "imgSrc" : "http://somewhere/db_schema.your_download_proc?p_file=#ID#",
}And then you can use this new attribute to populate the images in javascript using standard img tag
See this tutorial http://docs.oracle.com/cd/E14373_01/appdev.32/e13363/up_dn_files.htm
I did not find any method in PL/JSON to pass image object)? So far I only found example to load images from local files to javascript.Hmm..I don't think you should load image objects.

How to display image that's in a table (BLOB datatype) in apex 4.0 report

I have an image that is in a table and I'm trying to get it to display in a report. The upload takes place on 1 page and the report is on another page. The source for the report page is as follows:
select firstname,
lastname,
decode(nvl(dbms_lob.getlength(IMAGE),0),0,null,
'<img '||
'src="'||
apex_util.get_blob_file_src('P1_PHOTO',username)||
'" height="75" width="75" alt="Product Image" title="Product Image" />')
detail_img
from user_image
P1_PHOTO is the upload item on page 1. My report is on another page. The image is not displayed in the report. Any ideas would be appreciated.

Hi Charlie69,
Go the Report Attributes -> BLOB Column -> Number / Date Format. Below this attribute you will find
the link BLOB Download Format Mask which will open a dialog to fill in following information:
1) Format Mask: IMAGE
2) BLOB Table: Name of the table where to find the required BLOB
3) BLOB Column: Table column name where you stored the actual BLOB
4) Primary Key Column 1: Primary key of the table where BLOB is stored
5) Primary Key Column 2:
6) MIME Type Column: (Table column name where you stored the required information about BLOB)(Type: VARCHAR2)
7) Filename Column: (Table column name where you stored the required information about BLOB)(Type: VARCHAR2)
8) BLOB Last Updated Column: (Table column name where you stored the required information about BLOB)(Type: DATE)
9) Character Set Column: (Table column name where you stored the required information about BLOB)(Type: VARCHAR2)
10) Content Disposition: Inline(If you want to show it in the browser)
11) Download Link Text: (Not necessary when you want to show image)
I have set the format mask accordingly and the image is displayed in my report.
Hope it helps!

Kiran

How to import images into BLOB datatypes

I know your original pl/sql routine contained a COMMIT, but did you use the same code with the COMMIT? If not, are you checking the table from a different session?
I ran your same code and it worked without issues. Are saying if you do a SELECT COUNT(*) from test007 it returns zero rows?

How to display images from BLOB column via APEX 4.0

Hello,
I did the following in order to display images of two Oracle records on the APEX page. I am using APEX Version : 4.0.1.00.03 , Oracle DB Version : 10.2.0.4.0.
1. Created An oracle table TEST_FORM
with 3 columns
( ID number, MIME_TYPE varchar2(255) , Image BLOB )
2. Inserted two records
10001, image/gif, ( actual image1)
10002, image/gif, ( actual image2)
3. created an Oracle procedure
CREATE OR REPLACE PROCEDURE show_my_form ( p_image_id IN test_form.id%type) AS
l_mime test_form.mime_type%type;
l_length NUMBER;
l_file_name VARCHAR2 (2000);
lob_loc test_form.IMAGE%type;
BEGIN
SELECT mime_type, IMAGE
, DBMS_LOB.getlength (IMAGE)
INTO l_mime, lob_loc, l_length
FROM test_form
WHERE id = p_image_id;
owa_util.mime_header(l_mime, false);
htp.p ('Content-length: ' || l_length);
owa_util.http_header_close;
wpg_docload.download_file (lob_loc);
END show_my_form ;
4. In Apex 4.0
step1. Created an interactive report on a new APEX page
step2. Specified the following in the Region Source
select id, mime_type, '<img src="#OWNER#.show_my_form ?p_image_id=#ID#" />' photo
from TEST_FORM
The column result shows as <img src="CCS.show_my_form?p_image_id=#ID#" />
I am unable to display the column image as a link to a proper image photo.
Could you please advise me if I missed anything ?
Thanks a lot.
Regards
Susanna

Maybe the space you have before the ? is causing issues. there shouldn't be any space.
Your procedure looks to be much the same of one that I have.
Have you granted execute on your procedure?
Also, what version DB are you running? This could be another issue: http://daust.blogspot.com/2006/04/xe-calling-stored-procedures.html
But anyway, you don't need to create your own procedure these days. You could do the following:
in your query, have a column: dbms_lob.getlength(blob) photo ; save, then in column attributes for that column, apply a format mask. There is usually a link below the text box for the format mask - BLOB Download Format Mask, which will help you build the format mask. But it is documented here: http://download.oracle.com/docs/cd/E17556_01/doc/user.40/e15517/advnc.htm#BCGGJHEF

How to attach image, screen shot or excel table to master vendor copy.

Hi,
Please let me know how to attach an image or excel table into "header text" table. This has to be printed and sent to the customer. We use SAP GUI to create purchase orders.
Thanks in advance.
Kushal

Past the code into the post and then click on the post preview tab to check to see if the image rendered...it should show, if not, then either the code wasn't copied properly or the wrong embedding code was used.
That will provide a link to the image in separate browser window or tab. But if you place a "!" (an exclamation mark) at either end of the link (with no spaces or quotation marks), the image will then be displayed inline, within your post.

How can I Insert a BLOB into a Table from Java?

I have a Java class that creates an xml file from data in a non-sql data source. After it successfully creates and saves the file it inserts a record into an Oracle table to log the fact that an xml file was created.
Now the guy in the warehouse wants to get an email with the file attached. I have been looking into the apex_mail package, because we already have a procedure using htmldb_mail. However, that procedure is on our old server with HTMLDB 1.6 and it is not sending any attachments.
I think I have most of the apex_mail worked out, but I'm stuck on the blob thing. This is what I have so far:
* The Java program creates a String object called xmlDoc
* After xmlDoc is fully constructed, the file is written to the (Linux) server. This is accomplished with the following:
// writing the xmlDoc
fileDest = "/home/ewh/XMLOUT/";
fileName = "OrderEW_"\+orderNbr\+"_"\+ticketNbr\+".xml";
FileWriter fstream = new FileWriter(fileDest+fileName);
BufferedWriter out = new BufferedWriter(fstream);
out.write(xmlDoc);
out.close();
* Next I insert a record into the log file with:
// Add a record to the Oracle order_email table to let the mail process know that
// a new xml file is ready to be e-mailed to operations.
emailLogInsertQuery = " insert into ewh.order_email ( file_name, create_date ) ";
emailLogInsertQuery += " values ('"\+fileName\+"', sysdate)";
oraAction = oraStmt.executeUpdate( emailLogInsertQuery );
All of this is working fine so far. Now, I have added a blob type field to the order_email table, but I have no idea what to stick in there so that I have everything that apex_mail.add_attachment needs.
Here's a description of the order_email table:
SQL> desc ewh.order_email;
Name Type Nullable Default Comments
FILE_NAME VARCHAR2(30) Y
FILE_BLOB BLOB Y
CREATE_DATE DATE Y
SEND_DATE DATE Y
Thanks ever so much,
Gregory

Hi,
From within APEX one can enter blob data in database tables, view the data and also update the data. Also one can send a blob attachment in an email.
May be you can follow a combination of the following OBEs to insert BLOB data and send BLOB data from APEX:

" here ls_z_if_test_cv has the image in XSTRING format which has beeen retrived using METHOD get_bds_graphic_as_bmp of CLASS cl_ssf_xsf_utilities
" In your case you need to just use the select query n fetch it from your table; ( provided your image is store in XSTRING format )
How is your image stored in your database table ?
