Display BLOB Images from a SQL Server DB

I am using Crystal Reports X and SQL Server 2000. I have a table (TABLE_PICS) that contains images (the images are stored in the DB. I have another table (TABLE_NAMES) where each record references its related image by an ID.
What I want to do is create a report where I display each record from TABLE_NAMES with their associated TABLE_PICS images.
I created a report, and the link is valid, but the report only displays a thumbnail and the name of the image.
1. Can someone tell me how I can get the actual images to appear?
2. I would prefer the images not be stored in the DB. Can someone tell me how I can get the images on the report as explained above, without the images being in the DB.
TIA,
Jack

JAVA, sqlserver - Need to load an image from the sql server database

hi,
I need to load an image from the sql server database using java. I have connected to the database and getting all other records except the records for a photo (datatype = LONGVARBINARY) and Remarks (datatype = LONGVARCHAR).
I am using java and sql server db. The photo and remarks are stored in the db. and i need to show the image and the remarks fetching them from there.
I get the error :
Thread-9 org.hibernate.MappingException: No Dialect mapping for JDBC type: -1
How can I achieve this?
Thanks,
Gargi

Exactly. And are you using MySQL?
No. You are using Microsoft SQL server if I have to believe your initial post. A quick google tells me that the dialect class to use is:
org.hibernate.dialect.SQLServerDialect

Blank Image when using a gif image from a SQL Server Database

Hello,
I'm trying to use a field from a SQL Server DB that has embedded GIF files. In Crystal Reports when I add the field to the report the picture is blank for every row. Any ideas?

i'm having the same issue.
I believe crystal doesn't support gif datatypes.
I'm trying to either convert the images, or find a work around in crystal, but haven't found anything.

Sending image from MS SQL SERVER to Oracle BLOB

Hey all, we're trying update Oracle via a SQL Server linked server and we're having an issue with a blob column. The update from SQL is:
UPDATE Banner..GENERAL.PS_EBI_IF_TBL
set photo = a.blob_file, photo_change_date=a.blob_date
from PWNT.dbo.BLOBS a, PWNT.dbo.BADGE_V b
where a.ID = b.ID
and base_name = b.BADGE_BASE_NAME
and b.BADGE_blob_date > getdate()-.021
GO
The error we get is:
OLE DB provider "OraOLEDB.Oracle" for linked server "Banner" returned message "ORA-01747: invalid user.table.column, table.column, or column specification".
The syntax is correct, we can run it if the column being updated (photo) is not a blob, so we believe there is something else we have to do because of the blob. Has anybody done anything like this and know how it works? Thanks!
Tom

Given that there are no version numbers is your post I can imagine many possibilities for misconfiguration. Especially as an Oracle BLOB bears no direct size relationship to anything MS SQL could possibly support.

Displaying BLOB images from table in a report

I am trying to upload images to a table, display them in a report afterwards. I have succeeded in the first part, but not in the second. 
 
I can display images in a report if they are in located in wwv_flow_file_objects$ where they are automatically put after 'File browse... + Submit'. 
But, if I move (insert into table + delete from ..object$) I cant display it in a report correctly. I saw the HOWTO document (the code was from there), but for some reason, it doesn't work. 
 
What am I doing wrong? How should I correct the column link or the procedure? 
 
REPORT SQL: 
 
id, 
name, 
filename, 
img src="display?p_photo_id=' || nvl(id,0) || '" height="50" width="50"' 
--wwv_flow_file_objects$ display 
--img src="p?n=' || nvl(id,0) || '" height="50" width="50" ' img, 
BLOB_CONTENT, 
MIME_TYPE 
from images; 
PROCEDURE 'display': 
create or replace procedure display (p_photo_id in number) 
as 
l_mime varchar2(255); 
l_length number; 
l_file_name varchar2(2000); 
lob_loc BLOB; 
begin 
select mime_type, blob_content, name, dbms_lob.getlength(blob_content) 
into l_mime, lob_loc, l_file_name, l_length 
from images where id = p_photo_id; 
owa_util.mime_header(nvl(l_mime,'application/octet'), FALSE ); 
htp.p('Content-length: ' || l_length); 
htp.p('Content-Disposition: filename="' || l_file_name || '"'); 
owa_util.http_header_close; 
wpg_docload.download_file( Lob_loc ); 
end; 
 
Many thanks! 

Alayan - If you're using XE, that shoud be the first thing you tell us. There is a separate forum for that product.
But as long as you're here, a couple points: you reference the "display" procedure in the img tag without qualifying it with an owner. How is the Embeded PL/SQL Gateway supposed to know what "display" is (unless you created a public synonym)? Next, in XE you need to explicitly enable access to procedures that are invoked this way. See the XE forum for discussion about that technique and read the doc here: http://download-uk.oracle.com/docs/cd/B25329_01/doc/appdev.102/b25309/adm_wrkspc.htm#BEJCGJFJ.

How to display BLOB images from the Oracle database within Crystal

Let's say a have the following table
IMAGES
========
DOC_ID NUMBER
DOC_NAME STRING
DOC_IMAGE BLOB
The BLOB field can have any type of document: PDF, email, WORD, EXcel, etc. I would like to present the DOC_ID and DOC_NAME and let the user click any of them. Once the user clicks the document stored in the database as BLOB, it is rendered using the default application associated to the extension. For example if the file name is ABC.XLS open MSExcel if the file is abc.pdf open Acrobat.
I am using Crystal2008 and evaluating Crystal 4.0
Does this requires programming?
Thanks!!!

Hi
Crystal is a reporting tool and you canu2019t execute any code except free hand SQL. When you pull any BLOB fields in crystal, it takes as a picture field and if that field contains image only it will display in your report.
If you have any information other than image, it will not display any info in the report.
If you want to insert Word , PDF and Excel then you will have to insert as ole object and can manage with location of the files.
Thanks,
Sastry

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 ";
echo $numRows;
echo " is the number of rows returned for id = ";
echo $ID;
?>
Hope that helps

Displaying images stored in SQL Server

Display images from a SQL database

I want to display images from a SQL database. The images are in a table under a specific column and are stored as a link to the image. How would I display the images from the column in LabVIEW?
I'm using LabVIEW 2013 version 13 and SQL Server 2012
Paul Power
I have not lost my mind, it's backed up on a disk somewhere

Hi PauldePaor,
I hope you are well.
Once you have pulled the data from the database into LabVIEW in a string form (or path), you can simply use the Read BMP File (Or jpg, png depending on the file type) VI.
More information can be found here:

I have done exactly that in one of my applications.
I have extracted the image from the database as a byte array, and displayed it using a servlet.
Here is the method in the servlet which does the displaying:
(since I'm writing one byte at a time, it's probably not terribly efficient but it works)
 private void sendImage(byte[] bytes, HttpServletRequest request, HttpServletResponse response) throws IOException {
 ServletOutputStream sout = response.getOutputStream();
 for(int n = 0; n < bytes.length; n++) {
 sout.write(bytes[n]);
 sout.flush();
 sout.close();
 }Then in my JSP, I use this:
<img src="/path-to-servlet/image.jpg"/>
The name of the image to display is in the URL as well as the path to the servlet. The servlet will therefore need to extract the image name from the url and call the database.

Can you store an Image in MS SQL Server 2005

Hello,
How possible is it to store customer uploaded images to MS SQL Server 2005.
Any examples and is there a down turn to retrieving the data from the DB?

How possible is it to store customer uploaded images to MS
SQL Server 2005.
Yes, you can store binary data in a BLOB (varbinary) column. Google turns up tons of hits on "storing images in sql server 2005". For example
http://www.databasejournal.com/features/mssql/article.php/3719221/Storing-Images-and-BLOB- files-in-SQL-Server.htm
Any examples
http://livedocs.adobe.com/coldfusion/8/htmldocs/help.html?content=Images_05.html
is there a down turn to retrieving the data from the DB?
It requires more database storage. So it can bloat your database. Plus there is the resources involved in retrieving the images from the database. Usually, it is better to just store the file path and save the actual image files on the file system.

                            fos.write(b);
                        } hi this the code to retrieve the image from DB and write to a file.

Problem with displaying BLOB images on JSP page using a servlet

hi. I have a big problem with displaying BLOB images using JSP. I have a servlet that connects to the oracle database, gets a BLOB image , reads it, and then displays it using a BinaryStream. The problem is , this works only when i directly call that servlet, that is http://localhost:8080/ImageServlet. It doesn't work when i try to use that servlet to display my image on my JSP page (my JSP page displays only a broken-image icon ) I tried several coding approaches with my servlet (used both Blob and BLOB objects), and they work just fine as long as i display images explicitly using only the servlet.
Here's what i use : ORACLE 10g XE , Eclipse 3.1.2, Tomcat 5.5.16 , JDK 1.5
here is one of my image servlet's working versions (the essential part of it) :
 BLOB blob=null;
 rset=st.executeQuery("SELECT * FROM IMAGES WHERE ID=1");
 while (rset.next())
 blob=((OracleResultSet)rset).getBLOB(2);
 response.reset();
 response.setContentType("image/jpeg");
 response.addHeader("Content-Disposition","filename=42.jpeg");
 ServletOutputStream ostr=response.getOutputStream();
 InputStream istr=blob.getBinaryStream(1L);
 int size=blob.getBufferSize();
 int len=-1;
 byte[] buff = new byte[size];
 while ((len=istr.read( buff ))!=-1 ) {
 ostr.write(buff,0,len);
 response.flushBuffer();
 ostr.close(); and my JSP page code :
<img src="/ImageServlet" border="0" > If you could just tell me what i'm doing wrong here , or if you could show me your own solutions to that problem , i would be very greatful ,cos i'm realy stuck here , and i'm rather pressed for time too. Hope someone can help.

I turns out that it wasn't that big of a problem after all. All i had to do was to take the above code and place it into another JSP page instead of into a servlet like i did before. Then i just used that page as a source for my IMG tag in my first JSP. It works perfectly well. Why this doesn't work for servlets i still don't know, but it's not a problem form me anymore . Ofcourse if someone knows the answer , go ahead and write. I would still appriceatte it.
here's the magic tag : <img src="ImageJSP.jsp" border="0" > enjoy : )

Display BLOB (image) column in (interactive) report

Hi,
I have a field called "picture" in my table "details" which is of type BLOB. i also have a field for "MIMETYPE" and "filename"
i additionally have a "name" and "description" columns which i need to display along with the picture as columns in a report (preferably interactive).
i have also modified the BLOB display format as per
http://www.oracle.com/webfolder/technetwork/tutorials/obe/db/apex/r31/apex31nf/apex31blob.htm
what i am missing is the correct query. if possible, i would like to control the size of the picture rendered within the report like say 40*50.
I have also referred to the thread
APEX 3.1 Display BLOB Image
But i don't know how to place the
dbms_lob.getlength("BLOB_CONTENT") as "BLOB_CONTENT"
in my query.
The above also makes the report column as of type "number". is this expected?
Any help would be much appreciated.

Ramakrishnan

Something like:

 , description
 , dbms_lob.getlength(picture) picture
from
 details
if possible, i would like to control the size of the picture rendered within the report like say 40*50.For images close to this size it's easy to do this for declarative BLOB images in interactive reports using CSS. Add a style sheet with:
.apexir_WORKSHEET_DATA td[headers="PICTURE"] img {
display: block;
width: 40px;
border: 1px solid #999;
padding: 4px;
background: #f6f6f6;
}where the <tt>PICTURE</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, scaling large images 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. For improved performance and image quality, and where you require image-specific scaling you can use the database ORDImage object to produce thumbnail and preview versions automatically, as described in this blog post.

Stream-in images from client to server,without running the transmit code

Hello all,
Im using JMF for my current project.Right now,I am trying to only recieve images from the client without the client transmitting it.That is I dont want the transmit code to run on the client.
I should just be able to stream in the images from client to server, without running the transmit code on client.
Can this be done?
Thanks in advance

You'd just need to write an application that doesn't have a GUI (so, a console-based application) that listens on some pre-determined port for a message to start broadcasting. Maybe you'd send it the IP/PORT number to start broadcasting on. Once it receives that message, it'd start broadcasting the web cam to the IP/PORT number until it received a message to stop. Once it stops, it'll just go back to waiting for the next "start" signal.
<Side B>
On the other side, you'd write an application that sends the start messages, receives/displays the videos, and then sends the stop signal. This will have a GUI, and be your "control program" so to speak.
Then, once of have both of those programs working...if you're using Linux, you're done. If you're using Windows, you'd need to modify the <Side A> program so that it can run as a Windows service.
There are a lot of ways to do this, you can google it or look at the following link:
