BLOB column's image is not showing up in Forms

Hi All,
I am using Forms 10g. I created a default form (using wizard) for a table that has a BLOB column. Form builder automatically created an image item that corresponds to the BLOB column. The problem is that when I run the, the image item is always blank, and is not showing any image. Although I know that the BLOB column contains valid images, which I can see using PL/SQL developer tool.
The form is compiling without error, and also, there is no runtime error message. So without reporting a compile time/runtime error, the Form is not showing the image. Can anybody help me plz??? this is urgent, any help will be greatly appreciated.
Thanks in Advance.

Hi,
I am simply using the Forms default "EnterQuery" and "ExecuteQuery" buttons. I have not written a single line of code. That is, just using the forms default funcionality.
Thanks.

Insert picture in a blob column and show in oracle forms

I am using version 10g for both database and forms .
Please tell me how to insert a picture in a blob column that is stored in my 'c:\test' folder

To populate the Image Item you have to use the Webutil Client_Read_Image_File() built-in.

To add an Image Item to your block based on the table that contains the BLOB column, then give this Image Item the BLOB column name.
So that, all you have to do is to execute query on that block.

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
Ahamed Rafeeque CH

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.

Anyone have face the same problem..?? and how to fixed it..??

There is a known issue that sounds like the problem you are experiencing
10358200 - If a formula column exists in a data form, selecting the Suppress missing option does not hide rows that do not contain data.

How to open a file form a blob column?

I'm storing some files in oracle 9.2 in a blob column, although i can't open them using php 4, I'm using this script :
<?php
     $SQL="SELECT ID_ARCHIVO,CONTENT";
          $SQL=$SQL." FROM ARCHIVOS_PRUEBAS ";
          $SQL=$SQL." WHERE ID_ARCHIVO =".$v_ID_ARCHIVO ;
          $c=OCILogon("$v_USER" , "$v_PASS" ,"$v_CONEXION" );
          $s = OCIParse($c,$SQL );
          if (!OCIExecute($s)) { print "execution failed"; exit(); }
     OCIFetchInto($s,&$arr,OCI_RETURN_LOBS);
     echo $arr["CONTENT"]->load();
          ?>
it shows this error
Fatal error: Call to a member function on a non-object in ov_archivo_detail_test.php on [echo $arr["CONTENT"]->load(); ].
I know the data is stored correctly since i used toad to save and open the blob file and it was ok, but i still can't find a right way to show the file from the web.

If you are using version 9 or 10 use webutil.... Look in webutil.pll.
Use either one these two fuctions...

How to view PDF files strored in a BLOB column

Hi all,
I want to display a PDF file, stored in a BLOB column, in a form or through a JavaBean.
But the problem is more complicated then that. I do not want to retrieve the PDF file in the application server that show it through a browser.
Actually, I do not want users to get the entire file, I just want them to see it or print it.
I want, in fact, to display a "stream" of bytes through Oracle Forms. Not a file.
This one, sounded to be a good solution, but actually not. When the file was too big (multiple pages), the application was blocked until the entire file was loaded. And when you try to print it, it wasn't printed right. The advantage of this solution is that it is open-source so we can add methods to connect to the DB, retrieve the content of the BLOB column and displays it without downloading the file.
Here is a good solution. Really good, files are loaded quickly, the rendering is really good and the file is printed perfectly (as it was printed from Adobe Acrobat). The disadvantage of this solution is that it is not open-source and is really expansive.
As you can see, both solutions uses PJC.
So any help, any idea to solve my problem will be highly appreciated.
Thanks to all of you,
Amine
PS : I am using F&R 11gR2

Not entirely. At least we came to the conclusion it doesn't make (much) sense to block the save option of PDFs if you want to allow printing them
Anyway; there is of course another possibilty: you could always write your own java bean PDF reader; there are plenty of java PDF libraries available:
Open Source PDF Libraries in Java
The easiest way would be to choose one which can open a PDF from a URL and render it; I would retrieve the image via mod_plsql using WPG_DOCLOAD and simply use the PDF library to render the PDF. No tempfiles anyway, and if you don't implement it there is also no save button.
cheers

How to generate a .pdf output for a BLOB column?

Hi friends,
(Forms 6i)
I have a .pdf into a blob column and I want to show that .pdf as my report output...
Example-> The report only have this query:
select myblob_ column
from mytable
the column in database has the .pdf ... but when I execute the report, it only appears some information when I put the item to show as Text... But obviously it's not the ofriginal pdf...
If I try to put as OLE2 doesn't appear either anything and if I try to put it as an Image, it appears a message error.
Any ideas?
Thanks.
Jose.

How to show pdf or word icons for a BLOB column in a report?

Hi,
I am getting interested for the blob columns, I have created some columns for storing some pdf drawings and pictures for specific items in a table, it is ok to show a text like 'download' or any other text in the report by setting the following blob attribute:
DOWNLOAD:TICKET_DETAILS:ATTACHMENT:TICKET_DETAILS_ID::MIME_TYPE:FILE_NAME:::inline:Download
but instead of texts, I would like to show a small pdf image for my Blob file, or a word image or Excel image, according to the different file type.
how to do that?
and instead of inline or attachment this two options, I would like when the user click the image of the file, the browser will show the image in a new window, or a new browser tab.
I tried the inline option for my file at Google Chrome, but when it showed the pdf file within the browser, I cannot get back to my app by clicking the 'backward' icon at the browser menu, it will stuck there and I have to close the broswer and then login to the app again, instead of simply returning back to the previous page within the app.
Please help me out.
Thanks
Peter Yawei . Zhang

Please try using a query like below for your report.
SELECT ticket_details_id,
CASE
   WHEN NVL(dbms_lob.getlength(attachment),0) = 0 THEN NULL
   ELSE
      CASE
         WHEN mime_type LIKE 'image%'
            THEN '<a href="'||apex_util.get_blob_file_src('P101_ATTACHMENT',ticket_details_id)||'" target="_blank"><img src="/i/image_icon.gif" /></a>'
         WHEN mime_type = 'application/pdf'
            THEN '<a href="'||apex_util.get_blob_file_src('P101_ATTACHMENT',ticket_details_id)||'" target="_blank"><img src="#IMAGE_PREFIX#menu/pdf_32.gif" /></a>'
         WHEN mime_type like '%ms-excel%'
            THEN '<a href="'||apex_util.get_blob_file_src('P101_ATTACHMENT',ticket_details_id)||'" target="_blank"><img src="/i/excel_icon.gif" /></a>'
         WHEN mime_type like '%msword%'
            THEN '<a href="'||apex_util.get_blob_file_src('P101_ATTACHMENT',ticket_details_id)||'" target="_blank"><img src="/i/word_icon.gif" /></a>'
         WHEN mime_type like '%ms-powerpoint%'
            THEN '<a href="'||apex_util.get_blob_file_src('P101_ATTACHMENT',ticket_details_id)||'" target="_blank"><img src="/i/powerpoint_icon.gif" /></a>'
         ELSE '<a href="'||apex_util.get_blob_file_src('P101_ATTACHMENT',ticket_details_id)||'" target="_blank"><img src="/i/office_icon.gif" /></a>'
      END
END attachment
FROM ticket_details
WHERE ticket_details_id = :P102_TICKET_DETAILS_IDPlease note that I am using APEX_UTIL.GET_BLOB_FILE_SRC function to download the BLOB files. The first parameter of this function in my example query is P101_ATTACHMENT, which refers to page item of type "File Browse" on page 101, which is a DML form on table TICKET_DETAILS. Replace it with the appropriate page number. Please refer to "Working With BLOBs Procedurally" section of this APEX 3.2 documentation for more: [url http://download.oracle.com/docs/cd/E14373_01/appdev.32/e11838/advnc.htm#sthref2199]http://download.oracle.com/docs/cd/E14373_01/appdev.32/e11838/advnc.htm#sthref2199
Also I have the gif images representing various MIME types on my file server. For e.g., /i/excel_icon.gif. You can use #WORKSPACE_IMAGES# if you want to.

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.

How to insert a pdf or jpeg image into a blob column of a table

How to insert a pdf or jpeg image into a blob column of a table

Hi,
Try This
Loading an image into a BLOB column and displaying it via OAS
The steps are as follows:
Step 1.
Create a table to store the blobs:
create table blobs
( id varchar2(255),
blob_col blob
Step 2.
Create a logical directory in the database to the physical file system:
create or replace directory MY_FILES as 'c:\images';
Step 3.
Create a procedure to load the blobs from the file system using the logical
directory. The gif "aria.gif" must exist in c:\images.
create or replace procedure insert_img as
f_lob bfile;
b_lob blob;
begin
insert into blobs values ( 'MyGif', empty_blob() )
return blob_col into b_lob;
f_lob := bfilename( 'MY_FILES', 'aria.gif' );
dbms_lob.fileopen(f_lob, dbms_lob.file_readonly);
dbms_lob.loadfromfile( b_lob, f_lob, dbms_lob.getlength(f_lob) );
dbms_lob.fileclose(f_lob);
commit;
end;
Step 4.
Create a procedure that is called via Oracle Application Server to display the
image.
create or replace procedure get_img as
vblob blob;
buffer raw(32000);
buffer_size integer := 32000;
offset integer := 1;
length number;
begin
owa_util.mime_header('image/gif');
select blob_col into vblob from blobs where id = 'MyGif';
length := dbms_lob.getlength(vblob);
while offset < length loop
dbms_lob.read(vblob, buffer_size, offset, buffer);
htp.prn(utl_raw.cast_to_varchar2(buffer));
offset := offset + buffer_size;
end loop;
exception
when others then
htp.p(sqlerrm);
end;
Step 5.
Use the PL/SQL cartridge to call the get_img procedure
OR
Create that procedure as a function and invoke it within your PL/SQL code to
place the images appropriately on your HTML page via the PL/SQL toolkit.
from a html form
1. Create an HTML form where the image field will be <input type="file">. You also
need the file MIME type .
2. Create a procedure receiving the form parameters. The file field will be a Varchar2
parameter, because you receive the image path not the image itself.
3. Insert the image file into table using "Create directory NAME as IMAGE_PATH" and
then use "Insert into TABLE (consecutive, BLOB_OBJECT, MIME_OBJECT) values (sequence.nextval,
EMPTY_BLOB(), 'GIF' or 'JPEG') returning BLOB_OBJECT, consecutive into variable_blob,
variable_consecutive.
4. Load the file into table using:
dbms_lob.loadfromfile(variable_blob, variable_file_name, dbms_lob.getlength(variable_file_name));
dbms_lob.fileclose(variable_file_name);
commit.
