I asked a similar question once and the answer I got was - Don't.
Instead, store the images on a drive somewhere and store the path in the database.
But I'm no expert - that's just what I was told by someone who does this kind of stuff a lot.
Hope that helps.

How to store images in database and retrieve them back to page?

Well I don't know how to store an image file to a database (say MSSQL) from the JSP and retrieve it back whenever needed and put it on the JSP page? Please help me.

I am not sure how to store images in database but what you can do is store the image into particular folder using FileOutputStream and its unique name into the database...and than retrieve it from the folder using that name retrieved from database...

How t store images in database

hi
i want coding to store images,files in database

hi,
You can use the BLOB data type provided by oracle to store images in the database. BLOB (Binary Large Object). To Store data into the table, we need to use the DBMS_LOB package to manipulate the data and then store it in the table.
BFILE are used in combination with the BLOB to get the images into the database.
Thanks, VIkram

How to display image in database using html or php

i've try already to work this thing but i can't do it. anyone that can help me or give me any example or reference to resolve my problem to retrieve or display image(blob) from database. hope that all of you help me

Using JHeadstart, you can display a BLOB column from the database in HTML, by way of ADF. Check out the JHeadstart Tutorial at http://www.oracle.com/technology/products/jdev/tips/muench/jhstutorial/index.html to get started, then do the same for your own database tables that include the BLOB column. JHeadstart will take care of rendering it as a file upload or image, depending on the display type you set at the attribute level.
Hope this helps,

2. Here I can not change the data type of any column.
Now how to store images in the oracle table using odbc or any other tool.

I wrote an example for my students, you can find it here. It's using PHP as the front end but all you need to do is know how and leverage the stored procedures. All code is downloadable in zip files from the blog.

How do you query Oracle RDF database using Java program?

Does anyone know how to get data out of the oracle RDF database using Java?
I'm running the following java code and it returns basically null values. My guess is that the get_triple() function returns a dataset other than resultset. I've tried searching the Oracle web site. Am I supposed to be using CLOB object? Any help would be appreciated. Thanks
sql = "SELECT a.triple.GET_TRIPLE() AS triple FROM family_rdf_data a";
ResultSet rs = stmt.executeQuery( sql ) ;
while ( rs.next() )
System.out.println( rs.getString(1) ) ;
rs.close() ;

get_triple() returns an object, and the code would be different from the code of retrieving a string. Some sample code for retrieving objects is at http://www.oracle.com/technology/sample_code/tech/java/sqlj_jdbc/files/advanced/advanced.html
get_subject(), get_property() return strings so the code below should work. get_object() returns a CLOB so different handling would be required and there is some sample code at the link above.

thanks a lot

While duffymo is correct in regard to most major database products, it's my understanding (warning! wild-ass guess coming) that the Hypersonic DB is more "application-centric" and the dynamic creation of databases is part of its design. It's pure Java database software, and therefore is not appropriate for all database projects, in particular those that require extremely high-performance.
See http://hsqldb.org/
I've not used it yet (but soon though), and I can't really advise anyone about it.
However, I'm wondering if you phrased you question in a way that is confusing us. To most of us in casual conversation, a "database" is both (1) a large organized collection of data and (2) the software that is used to organize and access it. However, the phrase "create a database" usually means creating a (1) database (a collection of data) using an already created (2) database software, such as Oracle, MySQL, DB2, HSQDB, etc., etc. If you'r question is, how do a create some new database software using Java, the answer is that this is a very very big and hard thing to do for the general case and probably not something you want to be doing.

How to restore a mysql dump file to database using java

hai friends,
i'm developing an application. in that i need to back up and restore the database. i'm using mysql.
in that i used a code to back up the db.. its working perfectly and the dump file is created perfectly..
but while trying to restore the dump file nothing is happening...
can anyone provide me a sample code to restore the dump to database using java code...
thanks in advance...

The first, biggest mistake you made in the code is that you didn't read standard output and error from the process, and/or you're ignoring exceptions. Because if you did, you would have read error messages that would have given you a clue what's wrong. (either that, or you ignored the clues, or didn't understand them and failed to tell us what the error messages are)
The second mistake is that you invoked exec with the call that takes a single string, when that string includes whitespace not used as delimiters.
The third mistake was that you used a terrible subject line for your post. Your problem is that you're having trouble with Runtime.exec. The fact that it's about mysql isn't relevent.
The fourth mistake is that you didn't mention Runtime.exec at all until pushed. You should provide these details. When you try to self-diagnose something that you don't understand, and then hide information, you're just wasting everybody's time, including your won.
The fifth mistake is that you're using poor spelling.
The sixth mistake is that you still haven't said why you're doing this in Java.
