I want to connect my java program to the SQLite db. What are necessary steps that I have to follow. I want to install sqlite database on my system to access the database.
From the SQLite Homepage:
SQLite is a in-process library that implements a self-contained,
serverless, zero-configuration, transactional SQL database engine.
[...]
SQLite is an embedded SQL database engine. Unlike most other SQL
databases, SQLite does not have a separate server process. SQLite
reads and writes directly to ordinary disk files. A complete SQL
database with multiple tables, indices, triggers, and views, is
contained in a single disk file.
So you don't actually install SQLite. To create and work with SQLite Databases, you can use the provided sqlite-shell, which is a command-line tool. If you are familiar with SQL, this should not be a problem.
Although, there are also some GUI-tools out there to work with SQLite...
If you want your Java-application to access and work with an SQLite Database, you'll need the necessary drivers. A nice topic on this can be found here.
Hello mayur rahatekar,
Here's a quick tutorial for creating a sqlitedb on your computer, its explained from the ground of:
SQLiteDB with some Androidflavour

You can take the help of mozilla firefox browser.If you have then you can search on google how to integrate sqlite with mozilla.it's very easy.Click here to see the link.

I successfully connected to a DB in eclipse through the Database Development perspective and am able to run queries in the SQL File Editor. However, I would like to write java code to automatically run a query and then extract the data to a flat file. What is the easiest way to do this? Since I am already connected to the database, can I bypass the java code that involves connecting to the database.
No, the Java JVM also needs to be able to connect to the database. There are many examples of JDBC connections on the internet, including this one.
Once you have got the data you needed, you should make use of FileWriter in order to write the information to file.
I created an android app. and I used sqlite to keep my small files. When I use sqlite, I could create tables, and did operations with just a java class.
Now I am creating pure java application, and I need small database that can be created with programmatically on java application like android sqlite.
Is there any java database like sqlite ?
You can still use Sqlite, also you could use H2 which has similar features.
Short Version: I need to store some data between runs of a java program.The data will be of the form of a table.Is there anything that can let do something like a sql query in java??THE SOLUTION MUST BE ABLE TO RUN ON AN OFFLINE COMPUTER.
Long Version: The user will be entering some data daily and i want something like a sql table in java. The program will run on a computer that is NOT CONNECTED TO THE INTERNET and so i need a truly local way to store data(Lots of it).Also preferably the data should be stored in such a way that it is not easily accessible to the end user(as in ,he should not be able to double click the file and simply read its contents)
Major Constraint: On searching online i found many people were using localhost to solve similar problems but that facility is not available to me as i CANNOT INSTALL ANYTHING on the target computer.
If a simple data file is not good enough, how about using SQLite with a JDBC backend? It will allow you to have an SQL database stored in a regular file with no dependency on any kind of server. Alternatively, there are many other embedded DB engines that you could use, depending on your needs.
EDIT:
By the way, most (if not all) DB engines that I know of do not obfuscate the data before storing them in the filesystem. The data will be fragmented, but parts of it will be visible if you force an editor to open the file (e.g. using "Open with..." in Windows).
There is also nothing to stop your user from accessing the data using the command line utility of the selected DB engine. If you want to obfuscate the data you have to do it in your code. Keep in mind that this will not stop a determined person - if your application can read it offline, so can everyone else.
Use an embedded database (like Apache Derby, HSQLDB, H2) so that you don't have to run a database server on the machine. The data will be stored locally on the target machine and it won't be human readable.
You have several options:
Store it in an xml-file
Store it in an local installed database
You can install a database like mysql or use a in memory database like sqlite or hbase or apache derby, which is included in java 6
I have set up mysql database to run with java and eclipse on my Mac, it is running great, but now I will generate aprox 4.3billion rows of data which will take up approx 64gbs of data, I'm storing a large about of keys and encrypted values, I have a 1TB external i would like to use as a storage location, i first thought i could reinstall mysql onto the external but it no luck as it obviously isnt running mac osx, Is there anyway i Can point mysql to store a database on the external, i have done some searching but have not come across an answer yet.
I am running Java to build and query the databse and Table if this comes into play.
Thanks.
Find your mysql config file (typically called my.cnf). Change the database path.

Don't reinstall mysql. You should use both the hdd and the external hard to store the data (rows/tables..) for mysql server.
Maybe by changing the path, but I haven't tried that.
Firefox 3 stores the bookmarks in a sqlite database.
There are several hacked sqlite java libraries available.
Is there a way to hack the sqlite database in java(not using libraries) to read bookmarks reliably?
Does someone know how the sqlite DB is stored and access programmatically (from java)?
You need the SQLite JDBC driver (this page explains how to run queries on a SQLite database using that driver from within Java).
I don't know why you need NOT to use a JDBC driver, but there's another possible "solution" depending on your software requirements. In FF3, type in the address bar about:config
Alter the value of property: browser.bookmarks.autoExportHTML to true.
This will export your bookmarks in an HTML whenever you close FF. You can then read the HTML. It may or may not solve your problem....
