Images from MySQL

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,
Terry

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.

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 you

You 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.

Retrieving Images from Mysql with PHP

Hi I have been trying to work this out with no success so some help would be really appreciated.
I have two tables in Mysql,
IMAGES AND EXHIBITORS
IMAGES
`image_id` INT(5) UNSIGNED NOT NULL AUTO_INCREMENT ,
`filename` VARCHAR(255) CHARACTER SET 'latin1' COLLATE 'latin1_bin' NOT NULL ,
`mime_type` VARCHAR(255) CHARACTER SET 'latin1' COLLATE 'latin1_bin' NOT NULL ,
`file_size` INT(11) NOT NULL ,
`file_data` LONGBLOB NOT NULL ,
`user_id` VARCHAR(50) CHARACTER SET 'latin1' COLLATE 'latin1_bin' NOT NULL ,
`accom_id` INT(5) NOT NULL ,
`exhibitors_exhib_id1` INT(5) NOT NULL ,
PRIMARY KEY (`image_id`, `exhibitors_exhib_id1`) ,

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

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
sandro

In 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

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
Cliff

How to insert, select image from database

can any one help me to store and retrive image from mySQL database....
plz can any one send me code for this ?
thank you

First of all, I suggest not to do this!! Creates to much overhead on your database. Especially if you have large images that your going to put in the database.
Otherwise what you could do is create a BLOB that contains the bytes to your image and insert that into your database.

Hi,
I'm using Mysql-database with blob column. I'm trying to show one image on the page. Now I only get red cross, not image.
I followed advices by jprazak:http://swforum.sun.com/jive/thread.jspa?threadID=47085&tstart=0
I changed code for my purpose.

And image-component to the page, url-value:
http://localhost:18080/application_name/servlets/DisplayPicture?imageid=1
I get no errors. What is wrong with this code?
Thanks

If I select DEMO_BLOB and BLOBCOL from servers window, I can see in properties window:
SQL Type BLOB
Type Name BLOB
If I select IMAGE column from mysql-table and I can see in properties window this:
SQL Type LONGVARBINARY
Type Name longblob
Could this SQL Type difference be the reason why I can't get images from mysql to the page?

Loading Images Dynamically from MySql

Hello
I need to load images in my swf file dynamically from MySql
using PHP. Brief is I have one Swf file and and i want to animate
image in it but image should be come from dynamic path.. anybody
can tell me how to do this? if you want more brief then i can
provide it but it is urgent...
Thanks in advance

I'm afriad I don't have a solution to your problem but I was
curious as to why you would load it from a database vs a directory.
I know you can have users upload to a directory and a database but
I don't understand the benifit since I think you'd be adding load
on the database server. Is it a server side image manipulation
thing?

How to insert a dynamic image from a database

I've recently started using Dreamweaver CC to set up a Dynamic Website (PHP pages with a mySQL database). With perseverance and by downloading the new depreciated Server Behaviors and Bindings Panels I've been more or less successful at accomplishing my tasks. I'm still struggling with getting a image to display from mySQL server data base. In the Pre CC revisions this was easy and well documented. I've downloaded the DMXZone HTML5 Data Bindings extension. I can almost get accomplish my dynamic image task, but the DMXZone HTML5 Data Bindings extension says I must now get the the "unfinished but working on" DMX Zone Database Extension in addition to the HTML5 Data Bindings Extension to select my data source from the database.
I'm thinking about dumping Dreamweaver CC altogether and just installing CS6 until the path gets better paved. Any other ideas? Sample code? Work around? Thanks in advance

Really you would do it like any other piece of information in your database.
Store the actual images in a folder on your server and the image file name in the database - myImage.jpg
Then echo it to the page following the convention of your other data which is being echoed onto the page:
<img scr="images/<?php echo $row_rsRecordSetName['images']; ?> alt="" >
['images'] above being the name of the database field in which you stored the image name and $row_rsRecordSetName being the variable created by the recordset (yours will be different)

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

A Fluid Gallery from MySQL using PHP and various column widths

I have decided to try the new Fluid Layout option in Dreamweaver. I pull information from a database (MySQL) and use php to present it.
To show a gallery, I would pull the info and use the repeater code, and something like Tom Muck's horizontal repeater script to create a gallery. The images need to be shown with other text-based information (not just a caption). However, the HR script is a set amount of columns - and I want the number of columns to change depending on the width of the browser.
So it's more than just a gallery - pulling images from a database with Title = "x" these would be a repeated stylised DIV with multiple texts fields and styles within.
Let's take the example of a car dealership website it must show the car image, year, prices, description etc all in different style fonts so it can just be a caption to the image.
So the options are:
A fixed number of columns for each width: Monitor 5, Tablet 3, Mobile 1. Can this be achieved by having a "IF" statement in the actual code, if width = x use this version of the Horizontal Repeater?
A fluid version that has 6 columns and as you slide the browser's width you can see the gallery's width has less columns until it reaches 1 for mobile.
The fluid version would be better.
Any links to a tutorial or example would be most appreciated.
Many thanks

The only issue with using <divs> instead of a table to create your grid columns is that you will have to set a minimum height on the <divs> to keep them all at the same depth,much like a table cell construction looks and behaves. If you don't set a minimum height the grid will look all ragged PLUS the very big drawback is the <divs> won't clear if another <div> has more content in it which is going to happen if you include a 'description' of the car as this will never be the same length unless you are prepeared to edit the text.
See fluid sample below: You can just populate the <divs> from your database and loop through them

Retrieve images from DB and attach them to email through javamail

Hi,
I'm trying to use javamail to send emails containing text and images (HTML mail), if I use a physical file in my computer as the image source and use FileDataSource everything works just fine. The problem is that the images in my app are stored into a DB (I'm using MySQL, java struts & DAO), so in order to retrieve & display them I use a jsp that returns a byte array as shown in the example bellow
<img src='getImage.jsp?itemId=<bean:write name="item" property="itemId"/>&heigth=180&width=140&imageIndex=1'/>getImage.jsp reads the image from the DB for the specified item and returns an image of size "heigth*witdh", this works fine when invoked from any jsp or java action class, but I can't get it to work to insert an image into an email as attachment
I've tried to use ByteArrayDataSource and the mail is sent correctly and can be read but the image won't show
bds = new ByteArrayDataSource("/getImage.jsp?itemId="+itemId+"&heigth=180&width=140&imageIndex=1", "image/jpeg");
imageMime.setDataHandler(new DataHandler(bds));
imageMime.setHeader("Content-ID", "<\" + itemId + \">"); // backslashes aren't there in the real code, but if I remove them '+ itemId +' won't show
mailParts.addBodyPart(imageMime);I've also tried with URLDataSource but can't get it to work either, can somebody plz point me in the right direction?
thanks in advance

Hello bshannon,
Thanks for your answer, I tried your suggestion but when I use URLDataSource I get the error message http 500 (in my original post I said that using URLDataSource the mail was sent but without the image... my mistake, I was getting this same error). I traced the error and I found that it is caused by a null pointer exception... let me explain
This is the code for the jsp that returns the image:
4        <jsp:useBean id="coverImage" class="com.mqm.struts.getImageAction" scope="session" />
5       <%
6           // Desired size of the image to return
7           int heigth = Integer.parseInt(request.getParameter("heigth"));
8          int width = Integer.parseInt(request.getParameter("width"));
9
10          // Each item can have up to 6 images (ordered by id), this indicates wich of one we have to return
11            int imageIndex = Integer.parseInt(request.getParameter("imageIndex"));
12        byte[] imgData = coverImage.getItemImageAction(request.getParameter("itemId"), request,heigth, width, imageIndex );
13        response.setContentType("image/jpeg");
14        OutputStream o = response.getOutputStream();
15         o.write(imgData);
16         o.flush();
17         out.clearBuffer();
18         o.close();
        %> getImageAction is my DAO class that actually reads the image data from the DB, when I use this 'getImage.jsp' inside any other jsp in the app it works, but when used as described in the first post the request parameter in the line 12 doesn't have the session info, apparently creates a new session or something and since I use information in the session to create the DAO factory I can't connect to the DB and get this error..
pls tell me if I explained my self or I'm just talking non sense
regards

Store and Display Image from Database

Now that MySQL is working (woo hoo!) with JSC, I have a couple of questions for any experts out there...
1. How would I perform an image or other file upload from a browser?
2. How would I retrieve and display an image from a db on a jsp page?
Thanks for any help.

Craig, I think I have a simpler way to load an image on the page, although for the time being I'm not retrieving from a database, but from the file system. The problem is that I'm not getting the pages to load continuously with new images. At some point it apears that the session gets clogges and can not load new pictures. I'll try to include the page bean code just below. This time I'm not adding the "code" tags because I haven't being successful with that. If you have problems , please, contact me at [email protected].
The core of the code is in a couple of button_action methods.
If you need, I can give access to the http server where this is running.
