Hi;
The python code works properly, so I assume this is a strictly MySQL

If I grab an image in the database thus:

cursor.execute(sql)
pic1 = cursor.fetchall()[0][0].tostring()
# pic1 = cursor.fetchall()[0][0] // either this or the above line
and try and re-insert it thus:
cursor.execute('update products set pic1=%s where id=%s, ;',
(pic1, id))
i am not familiar with this python db abstraction class, but
the last comma seems to be wrong
try
'update products set pic1=%s where id=%s;'
instead of
'update products set pic1=%s where id=%s, ;'
or even without ';' too
and is this some sort of prepared statement, or are the parameters escaped
somewhere else?

Adding Images
Hi;
I´m trying to figure out how to upload images into a MySQL database. (Yes,
that is what I want to do.) I have a form that asks for data, like this:
1ra Foto Pequeña:
input type='file' name='pic1' /
Then I send that form to a python script that processes like this:
cursor.execute('insert into products (' + col_names + ') values (' +
col_values + ');')
where col_names is all the names of the columns and col_values, obviously,
the values. Works fine for strings and digits. Not so well for files :) What
do?
TIA,
Victor
Re: Adding Images
Victor,
you are on the wrong list. Your problem is not a MySQL problem (at
least, not yet) but a question of how python deals with uploaded files
(which, in ANY environment is radically different than the way normal
form elements are treated). Try the python groups.

You want to use prepared statements, bind varaibles, or placeholders
(depending on the terminology python uses) instead of manually building
queries by string concatenation.

RE: IMAGES/PICTURES-MYSQL
It all comes down to what you are most comfortable with. What I have done is to name each image file with a serial number (1.jpg, 2.gif, 3.png, ...) and store the path along with the real name of the image in a table row. Doing it this way means that you don't need to program logic to convert a blob in order to serve it up with a script, you just need to programmatically create a link to the image file and let the web server do it. I find that easier to work with, and certainly easier to debug.

mysql query question (images,tags)
hi to all, I have a simple question/szenario. Here are my tables: 1. image (id, name) 2. tag (id, name) 3. images_tags (image_id, tag_id) At the moment I have the following working query, it selects all images which have *at least one of the tag ids* (25,30) assigned. SELECT DISTINCT image.id, image.label FROM `image` JOIN `images_tags` ON image.id = images_tags.image_id images_tags.tag_id IN (25,30) Now my plan is to adjust the query so that only images are selected which have *all the tags assigned*, so the IN command in the ON clause does not fit anymore. Here is my attempt to replace the IN: SELECT DISTINCT image.id, image.label FROM `image` JOIN `images_tags` ON image.id = images_tags.image_id ( images_tags.tag_id = 25 images_tags.tag_id = 30 ) But it doesnt´t work :( It would be awesome if somebody could help me. thanks a lot! -jens -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Re: storing images in the database
Hi, In my honest opinion, uploading the image to a preset directory in the code, and setting the code to submit the image name, extension, and if needs be (it shouldnt, because you can set it in the HTML), the directory. Google has a lot of useful resources on this. But, if you are really desperate to do it using the BLOB type, http://www.wellho.net/solutions/php-example-php-form-image-upload-store-in-mysql-database-retreive.html was a help to me when I first started learning.

Granted we are using Sybase for that and not MySQL but there are a lot of advantages to it - access control, change control and tracking, easy insertion and deletion, and access from any client right through the database driver so you can repurpose content more easily. There are situations where it might be useful to store large amounts of binary data in a database. For most situations the best solution is to store metadata about the file in a database and store the file itself on a file system. There have been lots of discussions about it on this list in the past. From those discussions one could conclude that in general a file system is best for storing (large) files and the metadata about these files can live in a database. But there are situations where storing large files in a database has more advantages.

Re: upload images / mp3 more Than 1 MB capacity ---- please help
AS JIGAL SAID : make sure you are not creating an INSERT statement bigger than the max_allowed_packet setting for both your destination server and your client library (whichever ones you are using). If you attempt to create a packet that is too large, the server will _ignore_ it. Because the packet (SQL statement) is too large, it is considered malformed and any processing of it will be aborted. http://dev.mysql.com/doc/refman/5.0/en/packet-too-large.html http://dev.mysql.com/doc/refman/5.0/en/memory-use.html http://dev.mysql.com/doc/refman/5.0/en/server-parameters.html Shawn Green Database Administrator Unimin Corporation - Spruce Pine Kane Wilson [EMAIL PROTECTED] wrote on 10/13/2005 09:25:24 AM: thanx for the reply , usually , i uploading jpg and gif files into mysql database , there is no any issue. we can display them correctly. when i try to upload such huge mp3 files and some .jar files into the databse , i used mysqlcc GUI and SQLYOG GUI , from those interfaces also giving troubles. contents wont stored. my requrement is any how keep the contents , in the mysql database, i have high performance machine. so then i'm not worry about perforamnce. please , let me know how could be the way to store such files in a mysql databse ??? please help Jigal van Hemert [EMAIL PROTECTED] wrote: Kane Wilson wrote: But when i try to store little but huge gif files it wont store .

Re: upload images / mp3 more Than 1 MB capacity ---- please help
I tend to disagree - at my place of employment, a newspaper, we have hundreds of gigabytes of BLOB data (ad and page layouts digital artwork) stored in SQL databases. Granted we are using Sybase for that and not MySQL but there are a lot of advantages to it - access control, change control and tracking, easy insertion and deletion, and access from any client right through the database driver so you can repurpose content more easily. I have stored smaller amounts of BLOB data in MySQL for side projects in the past, without trouble. Do understand though that storing BLOB data in the db will impact your table optimization and repair times as well as backup/recover times. You might also want to plan ahead and devise a scheme to spread the data among several tables, to allow optimization of just one table a day (for example) and even to allow you to split storage across multiple devices should your database get too large.

Inserting Other Binary data into DB (NOT IMAGES)
Title: Inserting Other Binary data into DB (NOT IMAGES) Good afternoon all, I have a db (gasp!) that is holding images in a BLOB field already. I can upload and retrieve on the fly - no problems.

I have read somewhere that it can be done, however I have not been able to make it work with MySQL.

Re: Images to MySql Database in PHP or JAVA
Hi, Have you try google ? http://www.google.fr/search?hl=frq=storing+image+in+mysqlbtnG=Recherche+Googlemeta= I see pretty much a lot of stuff there ;) btw, storing image in a table in considering a bad practice, let the filesystem handle it it does it more efficiently. I would suggesdt to write the image on the disk, and then store the path in you db with useful thing like image format, width, height, etc... HIMH.

RE: How can I store Images in the MySQL Database
Hi Nikhil, Have a look at www.hotscripts.com for either a script that dose this or a tutorial to show you how to do it. But in general you DO NOT store the image in a MySql table you just store its location name i.e. 'images/image1.png' and then with a select statement use the result in a 'img src' string for your script. Here is another place to start for a PHP example but there a loads for other scripting languages. http://www.zend.com/zend/tut/photogallery.php I hope that helps Dave Carrera -- UK Web Hosting @ http://www.ephgroup.com -Original Message- From: Mulley, Nikhil [mailto:[EMAIL PROTECTED] Sent: 02 November 2004 05:05 To: [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: How can I store Images in the MySQL Database Hi Lists , My Query is How Can I store Images in the MySQL Database , and how to Index them , can anybosy help me on this please I am starting out a Online Photo Gallery and want to share them , and I want to make the search available, Does anybody has already done on this ?

Storing Images In MySQL
I figured I'd post a follow-up to the discussion earlier this week on issues relating to storing images in MySQL. In my opinion. Whether you store images in MySQL ultimately depends on whether you can setup a caching accelerator (like Squid) between you and your visitors. Storing images in the database adds a minimum of around 28 ms of latency. Cacheing makes this a mute point since images are once again stored as files. The main benefit is that you can more easily manage a large number of images by storing them in the database. Most people, those on shared hosting services, aren't going to likely have access to a caching accelerator, so originally storing images as files is probably going to be the best approach. The most common approach that I've seen is to create some sort of directory hiearchy and divide images in groups of 1000. Two other points came up while I was playing around with this. People on dial-up accessing test pages didn't notice any difference in performance - their average ping times to the server were around 120ms. I'm guessing their connection latency helped to buffer the difference between the two approaches. Pulling images from the database usually involves a script with a parameter that indicates which image to display. For example, like this: img src='http://www.myhost.com/display_image.php?id=5' Locally installed firewalls (Zone Alarm, McAfee Internet Security, and Norton Internet Security) all blocked the display of images that were served with a script like this. Getting the images to display required renaming the script, using Apache forcetype commands, and manually parsing the URL to get the image id to display. In other words, the url ended up like this: img src='http://www.myhost.com/display_image/5' Anyone who sends me a request can get copies of the scripts and help on trying to set something up to duplicate what I did.

RE: Images
What do you mean chunked? I figured it would be easier to track about 32,000 images in MySQL than in files, so I setup a test to see what the performance difference is and if storing in MySQL would actually work. Everything is working and it's a lot easier to keep track of the images in MySQL. I ran some performance tests using Apache's ab though and there's a huge performance difference - 38 times faster grabbing the file. It could be my test system here at home. I've asked my ISP to upgrade my production server to PHP5 so that I can run tests from there. There could also be performance hits in the script that grabs the images from MySQL, because I tried using OOP. I was told OOP would be a faster approach, but I'm pretty new to it and may not have done something correctly. I'm going to create some non-OOP scripts to cross-reference the tests. I only have one production server, so I won't be able to separate / dedicate servers. Your mention of chunking sounds promising though. Actually, I'd appreciate any ideas or recommendations you have.

RE: Images
Thanks for the link =) I understand what you're saying about MySQL not being designed as a filesystem. I've used this same argument with others. It's just that... well, have performance boosts have decreased the margin of difference? Especially when web-page caching is being used - don't the images get cached as actual files? If so, the original method of storage would be a mute point. That's what I'm trying to find out.

Re: Images
Most people make the mistake of using the biggest blob size to store files.. That blob size is capable of storing just HUGE files..What we do is store files in 64K (medium blob) chunks.. So if the image was say 200K in size, the metadata for the image would be 1 row in a table, and the image data would be 4 rows in the data table. 3 full 64K rows + 1 partially used rows. There is a good article/sample code here on the kind of technique we started with: http://php.dreamwerx.net/forums/viewtopic.php?t=6 Using chunked data, apache/php only needs to pull row by row(64k) and deliver to the client, keeping the resultset size low = memory overhead low. The storage servers (mysql storage) I have tested on the LAN; them storing and retreiving data from mysql (using FTP gateway) at rates of 4600K/sec.. which is I think the fastest speed my laptop network card could deliver.

RE: Images
Ok... I have some more test results. After optimizing as much as I can think of, without using caching, I've gotten things down to a 13x difference. Using Apache's ab performance test, the image comes from a file at an average of 2ms and from the database (using PHP4) at an average of 28ms. I know... it just reiterates what you were already saying, but it sure is great to see actual numbers measuring the difference. Maybe the difference could be even less if I were properly optimizing MySQL. The big question still outstanding, for me at least, is whether web page caching makes the performance difference a mute point. If caching is storing everything as files, we get the best of both worlds. Plus, I think there may be a little bit of a security benefit. A directory has to be marked as writeable so that scripts can store image files. This isn't necessary when using MySQL. Do you agree with the security benefit?

RE: Images
I read through the article and ran some more tests. The new scripts and tables provide similar initial latency, but I think the test results show them to be faster overall. When it comes to latency, direct file access is still the champion without caching. I think you made a good point about throughput which makes MySQL more appealing for storing larger files. That kind of surprised me actually, because I always figured I'd have to store things like PDF's on disk and control access to them by putting them outside of the document root. There's still a question of whether caching provides the edge and at what cost. I haven't set up caching, so I'm not sure if it's complicated or not. It would provide performance boosts to more than just images through, so it seems worthwhile to explore. That's what I'll be exploring next. =) -Ed -Original Message- Most people make the mistake of using the biggest blob size to store files..

images from MySQL backend used with MS-Access 2000 frontend
Hi everyone, I am new to MySQL. I am starting a database project for a medium-sized medical office. I chose MS-Access (on 10-terminal pre-existing Win2K intranet) for rapid front-end dev and familiarity to the existing users. I plan to use MySQL on Linux server for backend for its speed, great support and ease of use. The database will consist of doctor's reports, schematic drawings and photos (500K JPGs and 50K PICTs). I am planning to implement that with BLOB or, alternatively, with file system while storing links to files. Later we may add webaccess through MySQL webserving or by using Access webserving options. Has anybody done anything similar? What is the best way to implement image storage (and, in future, movies, maybe)?

RE: images from MySQL backend used with MS-Access 2000 frontend
I would recommend storing the images on the filesystem and put the information about those images (along with the path to the image) in MySQL. If you plan to have lots of images, implement a nice logical directory structure to keep them in as in my experience linux ext2/3 is fast reading/writing files in that scenario and can be slow in retrieving files in a single directory containing large amounts of files.

I am planning to implement that with BLOB or, alternatively, with file system while storing links to files. Later we may add webaccess through MySQL webserving or by using Access webserving options. Has anybody done anything similar? What is the best way to implement image storage (and, in future, movies, maybe)?

Extracting images from blob fields.
I have a small single user database into which I wish to insert and extract images. From the manual this seems to work to insert the image insert into images values(LOAD_FILE(/home/richard/scan.tiff)); but how do I get it back again? I thought this might work but it doesn't select * into outfile /home/richard/image.tiff from images; Note this is an experimental database having at present only one table with one field in the table and one record in the database. The file image.tiff seems to be full of escape characters when viewed with a binary editor. I can find nothing in the manual about how to retrieve the image and searching on the web only gives suggestions using perl, php etc to serve it to a web page but I don't have perl, php, apache etc I just want to extract the image and look at it with image magic or similar. Any advice will be greatly appreciated. -- Regards Richard -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Re: Extracting images from blob fields.
You need to select into dumpfile instead of outfile. See the section of the manual on select syntax: http://www.mysql.com/doc/en/SELECT.html -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Re: Images in a table
Here is a sample code in PHP:
$image = file_get_contents('/tmp/my_image.png');
$res = mysql_query('insert into img_table ( data ) values
(\''.addslashes($image).'\')');
Works with a table like:
create table img_table (bigint not null auto_increment primary key, data
LONGBLOB not null default '');

Re: Images in a table
Be warned about hitting the default max_packet_size limitation of mysql
which will cause large files to not insert.
This link shows another way to overcome that limitation:

Re: BLOB images in Crystal Reports
I want to ask you one thing: Is your Crystal Report accessing the database through the Mascon Utility or it uses MyODBC?

Re: images on database
The most common problem in such cases is that the webserver doesn't know what MIME Type the file is and so it doesn't know how to send it.

Saving BMP images as BLOB
Hi I am trying to save bitmap images in a InnoDB table in a field that is declared a lonblob. I am using the ODBC API of Microsoft Visual Studio 6 and saving it to MySQL via the MyODBC Driver version 3.51. The MySQL version is 4.0.12-nt. Seems like I can only save four bytes and retrieve bytes instead of the whole BMP. Here is the code for writing the image to a buffer - (char* image) CFile file; file.Open(filename.c_str(), CFile::modeRead | File::typeBinary); CFileStatus status; file.GetStatus(status); image = new char[status.m_size]; for (int i = 0; i status.m_size; ++i) image[i] = '0'; file.Read(image, status.m_size); I then make a query containing the buffer and then use SQLPrepare and SQLExecute functions to save the data to the database. Can anybody help? Franz Klein -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
RE: How can I display images from a mySQL Database in a web page?
What I have found that works, in PHP, is using a form that allows the user to browse for a file or an image. Upon submitting the form the file is uploaded to a set location on the web server and the name of the file is added to the database. When displaying the information associated with the image, write the php page so it has the image tag and all you do is query the database for the name of the file. Let php do the rest. I realize this isn't a php list but this is what I have done in the past. You can check the www.php.net newsgroups archives for steps on accomplishing this task.
