Images in Blob Column..

Hi
I have a function that retrieves the blob column which has the image data. I cannot view this from Toad and get the value {hugeBLOB} when I query via Toad.
I used it in a VB.Net app, but I'm unable to reterive the image there also. Can you please suggest how I can retrieve blob column (which has images) into a .jpg format? I need to retreive the images based on the query.
Thanks for all suggestions.

Hi,
Your question is not according to Forum. You must post your thread (for immediate response) on Oracle Forum for Dot Net/VB Forum.
But i'm going to accept your request.
I've inserted/ saved image in oracle 9i database. And As well i've read/displayed image into Picture Control from Oracle9i database.
But i've used C# Dot Net (Visual Studio 2005 Professional) as front hand tool.
Sorry for VB. One thing IMPORTANT:
I'm going mention code in C# you can Covert into VB Dot Net. Through Online FREE Compiler(www.developerfusion.co.uk/ and click on utilities.)
--------------------------------Here Below is C# Code ----------------------------------------------------
Con.Open();
string myquery = "Select Form_id,Emp_image From Employee where Form_id=2840";
OracleCommand cmd = new OracleCommand(myquery, con);
OracleDataReader dr = cmd.ExecuteReader();
Boolean recordExist = dr.Read();
if (recordExist)
//Now displaying Picture.
MessageBox.Show("Pic is being loaded by C#. Now");
OracleLob blob = dr.GetOracleLob(1); //Column #, Emp_image
Byte[] BLOBData = new Byte[blob.Length];
//Read blob data into byte array
int i = blob.Read(BLOBData, 0, System.Convert.ToInt32(blob.Length));
//Get the primitive byte data into in-memory data stream
MemoryStream stmBLOBData = new MemoryStream(BLOBData);
//LOADING INTO PICBOX1
Picbox1.Image = Image.FromStream(stmBLOBData);
MessageBox.Show("Now i'm reseting it.");
Picbox1.SizeMode = PictureBoxSizeMode.StretchImage;
Else
MessageBox.Show("Reocrd not found against this id.");
Hopefully it helps you. If it is still difficult to understand don't shy to make query.

Insert Image to BLOB column

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

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

      DBMS_LOB.Open(v_blob, dbms_lob.Lob_ReadWrite);
      v_srcfile := Bfilename('IMAGE_DIR', 'image.gif');
      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';

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.

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.

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.

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 ?

POL-3314 with BLOB columns

When trying to import images into BLOB columns, or read them back we get this error on WIN32 (surprisingly there is no problem at all on any of the windows mobile platforms like mobile 5 or ppc2003)
Does anyone have a fix/work around for this?
There is a bug 5880088 with a staus of 'Closed, not feasible to fix' on metalink, with reference to a note (waiting for this from Oracle as not accessible), but would be surprised if we are the only people wanting to store images in the database

work around is to select the data for update, rather than just select the data when wanting to retrieve BLOB data

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.

How can I insert a image into a BLOB column in a table?

I am using forms6i against a 10gR2 database and I have one table with a BLOB column and I try to insert a image into this column. I get ORA-01461 error.
The curious case is that in another table with a BLOB column it works very fine.
What happens with the first table? How can I avoid the error?
Thanks in advance.

Displaying images stored in blob columns

I've seen discussions on how to upload and download blob columns but I want to store a blob in the database and be able to display the blob (which is a jpg) as I would any other <img> on my web page. Instead of having to store the jpg on a file system somewhere, and use the data in the database to formulate a link to the image on the file share, I want to pull it right out of the blob. Does someone have a sample of how to do this? Can I do this?
Thanks

Laurence,
If you uploaded the image via the Application Builder, you can use an image tag like so:
<img src="#WORKSPACE_IMAGES#my_image.jpg" />If you followed the upload/download how to, you should be able to reference an image like this:
<img src="download_my_file?p_file=1232897645" />Where 1232897645 is the unique ID of the uploaded image. To make referencing images easier, you could write a version of the download_my_file procedure that takes in the name of the image as a parameter.

Inserting Image into a BLOB column in Oracle9i

Hi,
I am unable to insert image into a BLOB column. I am using Forms 6i REL 2 and Oracle 9i. But I could do it on Oracle 8i with same Forms version.
Same thing is true for CLOB in 9i.
Would you please try with this code?
TABLE
Create table x
(Id number,
Name CLOB,
Pict BLOB);
WHEN-BUTTON-PRESSED trigge
declare
     x varchar2(265);
begin
     x := get_file_name;
     read_image_file (x, 'GIF', 'picture.pict');
end;
Take care,
Tarek

Forms 9i and Oracle 9i work fine together for this case.

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.
