Retreving Image from Blob Columns in forms 6i

Hi
I inserted image into oracle database in an BLOB column Using Form6i. The table has only two columns, One is varchar2 and other is BLOB. The time it take for inserting image is very little, but retrieving from database to form is taking time. Can anybody suggest tips to improve the speed of retrieving?
Thanks in advance

What are you doing exactly?
select blob_column
from my_tablewithout a WHERE clause retrieves all images. Yes, that may take some time. Be sure to add a WHERE clause.

Retreving Image from Blob in forms 6

I am using forms 6 and oracle 9i.i have an image item and on when_button_press trigger i insert an image into the image_item by calling the read_image_file function and then save that image into the database.it gives me a message that 1 transactoion applied and saved. now i want to to retrived that image from database into form.how should i do it.also how will i know whether my image has been saved or not.when i tried to execute query i got message query caused no records to be retreived.
my table name is test_images and i have one column image(blob)

your test_image table better to have another primary key item like file_id number with table trigger to sequence generating its value for IF INSERTING event, or it will have no handle to get the image back.

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

Hello,
It is very difficult for us to "guess" what images you can read and what others you cannot.
Maybe you could provide more information on images that are not displayed ?
What is their native format ?

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.

Display image from BLOB field (png image)

Hello,
On my database i have a function which return BLOB (png image from a webservice)..
Is there some tutorial or sample code how to display a image froma blob field in oracle reports?
thank you

You can create a view and base your report on that view. The view would be something like:
create or replace view my_view as
select my_blob_function() image
from ...In your Report it would just be:
select image
from my_viewNow, I'm not sure if Reports supports png format, though.
There are many examples to be found, e.g.
http://download.oracle.com/docs/html/B10602_01/orbr_dyngraph.htm

How to upload/download file into/from blob column in ADF/JDev 11g.

Hello to all.
I found demo from Kuba user on that page: http://kuba.zilp.pl/?id=1
But that demo is for release 10g and too complicated for me for this time (I'm fish in Jdeveloper).
I can create some simple table view (of form view) with oracle connection with table with blob data.
Blob column will content doc/xls/pdf ...etc.
Now I can add two buttons for download and upload.
What I have to do in next time?
Is it possible to use some component or something?
Thank you
Ben

I was able to accomplish downloading from a blob, but I'm trying to dynamically set the ContentType.
As the table may contain different types of files, I'm setting the ContentType to #{row.Fileext}, where Fileext is set in SQL select as follows:
pseudocode: get file extension, and set the content type based on file extension.
sql select :decode(substr(fdv.file_name,instr(fdv.file_name,'.',-1,1)+1),'log','text/plain; charset=utf-8','xml','text/xml','xls','application/vnd.ms-excel','tif','image/tiff','jpg','image/jpeg','unknown')
I rather use a fuction/method, and tried the following instead:
ContentType = #{backingBeanScope.backing_processReqs.FileAttachContType}
where FileAttachContType =
public class ProcessReqs {
public String FileAttachContType() {
// code to substring filename for extension and decode values
return strContType
But I get the following error:
Error 500--Internal Server Error
          javax.el.PropertyNotFoundException: The class 'sunrider.reqpoportal.view.backing.ProcessReqs' does not have the property 'FileAttachContType'.
               at javax.el.BeanELResolver.getBeanProperty(BeanELResolver.java:547)
               at javax.el.BeanELResolver.getValue(BeanELResolver.java:249)
               at javax.el.CompositeELResolver.getValue(CompositeELResolver.java:143)
Ideas?
PS: Kuba, I've been trying to get to your blog all day, and it would just time out.
Thanks everyone in advance!

Display data from BLOB column.

Hi All,
I want to display data from blob datatype field, which contains HTML and GIF both files.
If I set it's property from file format IMAGE then i get data only gif.
if anybody have answer plz revert back...
awaiting...
Juned

Hi Juned
What I suggest is that you may have overlapping fields. One to show HTML and other to show GIF. You need to add one more column to your table in order identify if the BLOB is GIF or HTML.
In the Format Trigger of each of these two fields, inspect the value of flag column and hide one field if the datatype is not its type.
For instance, if flag field is 0 then hide Image field and show HTML field. If flag field is 1 then show Image field and hide HTML field.

How can I open different binary files from BLOB column ?

If we store some type of binary file (XLS, DOC, PDF, EML and so on, not only pictures) in BLOB column how can I show the different contents? We use designer and forms 9i with PL/SQL.
How can I copy the files from BLOB to file in a directory or how can I pass BLOB's content to the proper application directly to open it?

The mime type is just a string as explained above (e.g. application/pdf...). There are lot of samples here and on metalink.
E.g. add a column mime_type varchar(30) to your blob table. Create a procedure similar to the following:
PROCEDURE getblob
(P_FILE IN VARCHAR2
IS
vblob blob;
vmime_type myblobs.mime_type%type;
length number;
begin
     select document, mime_type into vblob,vmime_type from myblobs where docname = p_file;
     length := dbms_lob.getlength(vblob);
     if length = 0 or vblob is null then
     htp.p('Document not available yet.');
     else
     owa_util.mime_header(vmime_type);
     htp.p('Content-Length: ' || dbms_lob.getlength(vblob));
     owa_util.http_header_close;
     wpg_docload.download_file(vblob);
     end if;
exception
     when others then
     htp.p(sqlerrm);
END;
Create a DAD on your application server (refer to documentation on how to create a DAD).
Display the blob from forms (e.g. on a when-button-pressed trigger):
web.show_document('http://myserver:port/DAD/getblob?p_file=myfilename','_blank');
For storing blobs in a directory on your db server take a look at the dbms_lob package.
For storing blobs in a directory on your app server take a look at WebUtil available on OTN.

Insert Image to BLOB column

Hi,
How can i insert a image/largefile into table (having BLOB column) from sql plus?
Thanks

Hi!
Do this with PL/SQL.
CREATE TABLE image_tbl
filename VARCHAR2(4000),
image   BLOB
DECLARE
      v_blob       BLOB;
      v_srcfile    BFILE;

      DBMS_LOB.FileOpen (v_srcfile, dbms_lob.File_ReadOnly);
      DBMS_LOB.LoadFromFile(v_blob, v_srcfile, DBMS_LOB.GetLength(v_srcfile));
      INSERT INTO image_tbl (filename, image)
      VALUES ('image.gif', EMPTY_BLOB());
      UPDATE image_tbl
      SET image = v_blob
      WHERE filename LIKE 'image.gif';
      DBMS_LOB.FileClose(v_srcfile);
      COMMIT;
END;I hope that one will help you.

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.
