Image to mysql
Hi. Again I :) And new problem.
I connected to MYSQL and I try sent byte[] image to database. The same code but database type is MSSQL working good but when I change type to MYSQL and type field in base image->blob I have error
java.lang.NullPointerException
Length = request.getContentLength();
in = request.getInputStream();
PreparedStatement ps = conn.prepareStatement("INSERT INTO dbo.foto VALUES (?,?)");
ps.setString(1, opis);
ps.setBinaryStream(2,in,length);
ps.executeUpdate();
I think that blob(mysql) type is equivalent image(mssql). Is it? So what is wrong? THANKS

How can you upload an image to MYSQL using php?
Ok this is a joint thread with one of my other ones because no one else was posting on it, so I did not get what I needed, so, How can you upload an image to mysql so when some one logs on to my site, they see or can upload there own avatar, now there are loads of problems with this, 1) many people don't know how, 2) It's not every day you try to encode a image into mysql, 3) Letting people upload images into mysql can cause traffic problem with people trying to log in. So that's it.
Uploading images into MySQL is a bad idea, for more reasons than you mention. You should store the images in a directory on the server instead. But if you want to learn the hard way, here is the method:
The mysql data type must be blob.
The form enctype must be multipart, like this: enctype="multipart/form-data"
The form input field myst be type file, like this: <input type="file" name="upload"/>
Here is example code that prepares the variable $photodata to be inserted into the database.
$uploadfile = $_FILES['upload']['tmp_name'];
$photoname = $_FILES['upload']['name'];
$uploadtype = $_FILES['upload']['type'];
if ($uploadfile != "") {
$tempfile = fopen($uploadfile, 'rb');
$filesize=filesize($uploadfile);
$width=getimagesize($uploadfile);
$widthx=$width[0];
$heightx=$width[1];
if (($widthx > 102) or (heightx > 135)){
$image_too_big = " but the image size was too large and was not submitted.";
} else {
$photodata = fread($tempfile, filesize($uploadfile));
$photodata = addslashes($photodata); -

I think I am happy with the Mysql, and I have read the various arguments about storing images in mysql but for my purpose I wanted to store the image in the database.
I have already created the upload and the images have uploaded correctly and I can see the data in the database, however I just have been able to retrieve the images back into a webpage.
I have a .php file which is merging these to tables correctly but the image is displayed as

?>Hi Murray
You must despair with beginers like me, attachments showed as having been
sent so lets try again.
I have been able to find a tutorial that works well all the way through, I
can even see the images in the browser!! but only shows images individually
on a page.
http://www.phpriot.com/articles/storing-images-in-mysql/7
However, what I want to do is to have a page that links my images table and
another table, all of which I have set up and is working other then showing
the images. All was very straight forward until sorting out the image. If
I can work out what to take from the above tutorial that works into my page,
I am sure all will be fab.
Storing them in the mysql was my preferred method as there are not alot and
they can be low resolution and I thought it would be fairly straight
forward!! however finding out that I am having to adapt code as dreamweaver
doesn't support the blob attribute is getting me out of my knowledge.
All the best
Gilly

Hi;
I'm comfortable sending data to and from python scripts and as3, but what about blobs? I have images stored in MySQL. How should I get these into as3?
Thanks,

Here's an extremely quick guide to saving images in MySQL (or
any other
database for that matter): DON'T DO IT.
Databases are for storing data, not images. Store the images
in the
normal file system, and use the database to store details of
where the
image is located.
Yes, you can store images in a database, but it leads to
table bloat,
and fragmented tables. It also involves quite a lot of
scripting, which
is not automatically generated by Dreamweaver.

Exception When I try to insert a image to MYSQL.
Hi Folks,
I need some help. I am trying to insert a image in MYSQL.
I am using Struts, Msql 5.0, Tomcat 5.5, Struts 1.1. The column in MySQL where I am trying to store image is of type "Blob".
Here is the exception I am getting.
java.sql.SQLException: Syntax error or access violation message from server: "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''test',_binary'����\0JFIF\0\0`\0`\0\0��\0C\0
' at line 1"
Code in my Action class looks like..(ps. For testing purpose I have DB code in my action class only. And its a testing code only.)
UploadImageForm imageForm = (UploadImageForm)form;
FormFile file = imageForm.getTheFile();
PreparedStatement psmt = null ;
Connection conn = null;
conn = DBConnection.getConnection();
String str = "INSERT INTO mainImage (name, imageData) VALUES ?,?)";
psmt = conn.prepareStatement(str);
psmt.setString(1, "test");
System.out.println("in image db 4-1");
psmt.setBinaryStream( 2, file.getInputStream(), file.getFileSize());
System.out.println("in image db 4");
System.out.println(psmt.toString());
// set the Blob
psmt.executeUpdate();
System.out.println("in image db 5");
psmt.close();
psmt = null;
I have tried lot of different things but now I am clue less so I seek some help from you fellow developers. Any help would be greatly appriciatedThnx Guys after waisting few hours I realized there was a typo in my sql. But If any of you folk are looking for some code for image handing this works.

Question on retrieve image from mysql
i want to retrieve image from mysql database and display on GUI
can anyone tell me how to do
Thank youYou can use the JDBC API for Java Database Connectivity. With this you can obtain data from the database using Java. There is an excellent tutorial here at Sun.com: http://www.google.com/search?q=jdbc+tutorial+site:sun.com You can get the MySQL JDBC driver at their own site: http://www.google.com/search?q=download+jdbc+driver+site:mysql.com Get the most recent version which suits your environment. There is also good documentation available over there.
For displaying in the UI, the approach differs per UI. As you didn't mention which UI you are using, I can't help you further in detail. -

i have used multipartRequest to access parameter of file type input.
all variables and related packages r imported properly.no prblm in that.
code is here....................................
try {
MultipartRequest multi = new MultipartRequest(request, ".", 500000 * 1024);
File f = multi.getFile("uploadfile");
out.println(f.getName());
filename = f.getName();
String type = multi.getContentType(f.getName());
fis=new FileInputStream(filename);
byte b[]=new byte[fis.available()];
fis.read(b);
fis.close();
Blob blob=new SerialBlob(b);
Class.forName("com.mysql.jdbc.Driver");
Connection con=DriverManager.getConnection("jdbc:mysql://10.1.52.206:3306/test?user=root&password=delhi");
String query="insert into uploads (FILENAME,BINARYFILE,) values (?,?)";
pstmt=con.prepareStatement(query);
pstmt.setString(1,filename);
pstmt.setBlob(2,blob);
int i=pstmt.executeUpdate();
if(i>0)
out.println("Image Stored in the Database");
else
out.println("Failed");
} catch (Exception ex) {
out.print("*******************"+ex);
ex.printStackTrace();
please suggest me the way to upload image to remote server** not on local server.
its urgent.
Edited by: JavaDevS on Jul 28, 2008 11:41 AMi need ur help,we hav online site .Please don't use these juvenile abbreviations. It's impolite when you're asking for assistance not to make the effort to spell out all of the words. Moreover in a forum with an international readership the use of standard English will reduce the possibility of confusion.
I presume that your file upload is being placed in a different directory from that which you were expecting. I would suggest logging all paths (specifically filename) to see if this is an unexpected value.
Please explain further what you mean by "local" - is this a stand-alone application, or merely running a copy of the server on your local machine and doing the transfer (via the browser) to that? Are there any other differences such as the browser used? -
Saving image in MySQL database
Best groupmember,
I want to save my images in a MySQL database. After storing that in the database I want to be able to present it using a servlet. Something like this (show image with id=4 from the database):
<img src="/servlet/image?id=4">
Would be happy to be guided to example code or tutorials about how to store images in a MySQL database using Java.
-- Best of Times
Peter LauriOk for storing images you'll have to use the type BLOB (=Binary Large Object) for the rest i would suggest that you take a look at the jdbc-documentation....
this might help... :p

Streaming an image from mySql db?
hi all
i already stored an image into a mySql database
now i'd like to write a simple servlet to display it
anyone could help me?
thanx
sandroIn your servlet set the content type for your image (e.g. image/gif or image/jpeg). Then read the binay data from the database and send it to the browser.
This may help you

Loading And Displaying image From MYSQL

Displaying images from MySQL data base
I'm currently developing a Master/Detail
page set. The MySQL table containing the Detail information includes a 'blob' (MIME: image/jpeg - Attributes - BINARY) for storing a small image. Under phpmyadmin the images show where applicable.
In my Detail page I display the results in a table. All the values display except the image.
I selected Insert > Image
When the 'Select Image Source' dialogue appeared set 'select file name from' to Data source
Selected the data base field from the established records set
I left the 'Format' as 'None'
Clicked OK
Have I omitted to set something? How does Dreamweaver or the PHP code know hto to render this field?
Hope someone can make some suggestions to resolve this.
Thanks
Cliff
Other possible useful info:
Developing on Windows XP
Dreamweaver CS5
all versions of MySQL, PHP, Apache, IE8, Dreamweaver up to date.In my desparation this morning
I even tried to set up a mirror of your example witha separate table (just the 3 fields) and even that didn't work. The Proxy member was the same as yours except that the script was changed to LocalPHP.php . Therefore I presume that the error must have been in the webpage. Unfortunately I've since deleted the code so I can't send a copy of what I used.
The only suggestions I could suggest that may help others that are novices are (1) suggested code for the webpage (2) a diagram illustrating how the elements link or relate to each other. Hope that is thought helpful.
Thanks again
