Blob problem (Image storing or Currupted )

AOA!
I am working as a developer in a companey. we made a database for HRMS. In this database there is a table EMPLOYEE with a column PICTURE of type BLOB. We were using oracle 8i initially but when we migrate to oracle 9i, we are facing a problem in image storing. The situation is, database showing ur previously stored images (those have stored in oracle 8i) but when we save a new image in that table or any other table it seams to be saved but cannot retrived. I mean when we issue a query
SELECT EMP_ID FROM EMPLOYEE WHERE PICTURE IS NOT NULL;
It shows the new inserted records too (thats shows us that picture has been inserted) but when we issue query from a forms6i application it didnt show any image. In case of report, when we try to query a record which newly inserted with image, it says some thing like REPORT IS UNABLE TO SHOW IMAGE FORMATE etc.
The situation is for all table and all schema which is indicating us may be it is some thing due to oracle 9i headen technique or due to miss managment by us. we dont have DBA in our companey.
Please help us in this regard. We will be thankfull to you.

Problem in displaying images stored in Blob variable

Hi all,
I have a requirement where i need to retrieve the image stored in Blob variable in DB and display the image in JSP page.
I have written the below code to achieve this, it works fine
In JSP, I am calling a action in the <img tag
<img src='downloadPhoto.page?method=getPhotoInBytes&accessoryModelPictures.id.accessoryNumber=${photo.id.accessoryNumber}/> In my controller class
InputStream inputStream=accessoryPicturesLOB.getPicture().getBinaryStream();
byte[] theBytes = new byte[inputStream.available()];
inputStream.read(theBytes);
response.setContentType("image/jpg");
response.getOutputStream().write(theBytes);But the problem is, *if i right click on the image and select save picture as option i get a error saying "The system cannot find the specified file "*
Can you please tell me what is wrong in my approach/code
Is there any better approach to display image that is store in Blob variable ?
Please help on this.
Thanks in advance.

You need at least to set the filename in the content disposition header.

I think that both your SQL is wrong and your intended use is wrong. According to the SQL reference, the following seems to be a simplified definition that seems to match what you're trying to do. UPDATE <table> SET <column> = <expr>. So PROPERTIES should be a <table> of some kind and X should be a <column> of that table. This changes your PreparedStatement to *"UPDATE PROPERTIES SET X = ? WHERE NAME = ?"* Then you can do ps.setBlob(1, b) and ps.setString(2, ...). Because your statement is DML you must do ps.executeUpdate(). So your code might look something like this.
Blob b = ...;
String x = ...;
ps = c.prepareStatement("UPDATE PROPERTIES SET X = ? WHERE NAME = ?");
ps.setBlob(1, b);
ps.setString(2, x);
int i = ps.executeUpdate();
The executeUpdate() returns the row count (i.e. number of rows) of your DML statement. Try that and see if it helps.

Inserting images stored as BLOB in table to Oracle Report(10G)

We have some oracle reports(rdf) built in Oracle 10g. Now we are planning to update these reports to include images stored as pdf's on file system. We have loaded these pdf's as blob into tables. Is there a way to include these image/s into the reports.
Thx.

Easy answer: No, this is not possible. You can't show a PDF inside your report.
Since you are talking about just images, why do you even store these images as PDF? Why not as JPG or PNG (if you need best image-quality)?
Using a normal image in a report would be no problem at all.
Complex answer: Yes, this could be possible with an enormous effort.
You could write yourself a Java-Bean which reads the BLOB, uses something like "iText" to convert the PDF to a normal image, and then display this image.
I want to recommend to not use this solution since it introduces a really big complexity into you report where the usual solution of just storing images as images and not PDFs would give you a better result (and way better performance).

Reports JFIF image stored in a blob

Hi everyone,
I'm using forms & reports 10g release 1. I noticed that a image stored in a blob with a format of JFIF doesn't work well with in Reports. I get the rep-62203, cannot render error. When the datatype is longraw instead of blob, it works fine. But I can't use longraw, because built in in pl/sql doesn't allow to read the field passe 32K. So that's why we convert to Blob.
I made a few test: 1) I stored a simple jpg with Toad and It work fine with Reports. I stored with a form but of a format of GIF it works fine. But the JFIF just doesn't work reports. What's the problem?
How can this be solve?
I thought maybe saving the image prior calling the report into a file and then link it with report. That will be my last choice. I prefere not to got there.
Any idea?

Hi,
We finnally succeeded. Dsegard gave us the right solution. <div>It was the setup of the display that was on error. We use VNC as the display. Now the display is set correctly and the reports shows up fine.
By seting REPORTS_DEFAULT_DISPLAY=NO, It did work for both the server and the local host.
Thank you dsregard.</div>

Image stored in BLOB column crashes report's engine

Hi,
I have a report where I display logos stored in a BLOB column on the DB.
The report is generated as RTF.
When images have sizes of 624x168 or 423x324 everything is OK. One image, 1221x224, is crashig the report with a dr. Watson error.
Any idea why?
The size of the "bad" image file is 38K, and the "good" ones are about 300K.

I altered student table to store photoes of students. For this I added STIMG as blob, MIMETYPE,FILENAME,IMAGE_LAST_UPDATE COLUMNS to studentadmitted table. Image stored and displayed in report very nicely. With the following query

"COURSE_ID",
"SESSION_ID",
"CONTACT#" "CONTACT_H",nvl(dbms_lob.getlength(STIMG),0) IMAGE
from "#OWNER#"."STUDENTADMITTED"
Images are displayed in column but they have different sizes.Stick to declarative BLOB images as above. They can be resized in reports using CSS. Add a style sheet in the page Inline CSS property:
td[headers="IMAGE"] img {
display: block;
width: 75px;
border: 1px solid #999;
padding: 6px;
background: #f6f6f6;
}where the <tt>IMAGE</tt> value in the attribute selector is the table header ID of the image column. Setting only one dimension (in this case the width) scales the image with the correct aspect ratio. (The border, padding and background properties are just eye candy...)
However, if the original images are large then scaling them in the browser this way is a huge waste of bandwidth and produces poorer quality images than creating proper scaled down versions using image tools. Downloading megapixel images and then reducing them to thumbnail size results in pointlessly pushing millions of bytes that will never be seen.
For improved performance and image quality, and where you require image-specific scaling the best approach is to use the database ORDImage object to produce thumbnail and preview versions automatically. Note that this is not possible in Oracle XE as Multimedia is not included

Cache of Displayed Images Stored in a BLOB

I would like to know how I can cache the data that is an image stored as a blob? This is for when I refresh/revisit/branch to a page taht contains images sourced from a blob, such that it does not compel the browser to regenerate the blob image file data?

Hi!
We use jsp (for example ManagerPhoto.jsp), which is deployed to OC4J:
Blob managerPhoto;
response.reset();
response.setHeader("Content-Disposition", "attachment; filename=manager_photo.jpg");
response.setHeader("cache-control","public");
ServletOutputStream outputStream = response.getOutputStream();
outputStream.write(managerPhoto.getBytes(1, (int)managerPhoto.length()));
out.clear();
out = pageContext.pushBody();
And HTML-code in the page to display an image:
<img width=120 height=149 src=".../ManagerPhoto.jsp?p_orun_id=11">

Problems displaying images stored in SQL Server as Datatype "image"

I am trying to display an Image stored in SQL Server as
datatype
'image' and it only shows a portion of the image.
It seems to be tied to the size (kb) of the image since the
larger the
image the less of it is shown before it cuts off(sometimes it
cuts off
mid line so it's about the file size and not fitting the
image on the
screen).
Here is the code I am using that deals with the image.
[Bindable]
public var theImage:ByteArray = new ByteArray;
private function getScans_result(event:ResultEvent):void{
var imageByteArray:ByteArray = event.result[0].Image;
theImage = imageByteArray
<mx:Image id="theIMG" width="160" height="220"
source="{theImage}"/>
Any Thoughts??

I do that sort of thing using PHP and mySQL the binary part
of the image is stored in a BLOB field (Binary Large OBject) along
the rest of the information necessary for the http headers (e.g.
mime type, file name, file size) being staored in their own fields.
That info is then used to build the file using PHP. The PHP
file contains a mySQL query whos result is echoed with the
appropriate headers. The URL points at the PHP file rather than at
any saved image.
Here's the php:
<?
# display_imagebank_file.php
# Note: the ID is passed through the url e.g.
# this_files_name.php?id=1
# connect to mysql database
mysql_connect('HOST', 'USERNAME', 'PASSWORD');
mysql_select_db('DATABASE');
# run a query to get the file information
$query = mysql_query("SELECT FileName, MimeType, FileSize,
FileContents FROM blobTable WHERE ID='$id'");
# perform an error check
if(mysql_num_rows($query)==1){
$fileName = mysql_result($query,0,0);
$fileType = mysql_result($query,0,1);
$fileSize = mysql_result($query,0,2);
$fileContents = mysql_result($query,0,3);
header("Content-type: $fileType");
header("Content-length: $fileSize");
header("Content-Disposition: inline; filename=$fileName");
header("Content-Description: from imagebank");
header("Connection: close");
echo $fileContents;
}else{
$numRows = mysql_num_rows($query);
echo "File not found <br>";
echo $numRows;
echo " is the number of rows returned for id = ";
echo $ID;
?>
Hope that helps

How to get the path of the image stored in sap??

Hi All
The problem is
While making an entry in standard there is a field called documents through which we attach our images in sap.
How to get the path of the image stored with the corresponding order so that the image can be displayed while we are creating a report.
I know how to upload the image while creating a report using docking control.
I am not able to get the path of the image stored...
Please Help
Thanks in advance..
Pooja

I am not aware of exactly which tables are used for storing the attached doc. details, but we have worked in the similar requiremnent.
What you can do is .... before uploading the image to any order, try swich on the SQL trace ST05 and after upload switch off.
The log will display what are the tables involved while storing the image. And you can easily find out the image location.
