Help!! How To Connect Java & PostgreSQL Database

I'm final year student in comp sc. I'm doing java in my thesis.
How to get/read data from postgresql using java?
My thesis is "2 Dimensional Graph Statistics Online Viewing Using Java Applet". So i need a mechanism how to read data from postgresql database using java programming. Please Help!!

Hi,
getting started you need some basics on JDBC.
Have a look at the tutorials, or look at this site (its german):
http://www.furchur.de/de/informatik/laborberichte2.htm#dbswt
Have a look at the java.sql package.
First you need to build up a connection using
java.sql.DriverManager.getConnection(...)
The parameter for the PostgreSQL you must look somewhere.
After you have a connection you can use Statements and PreparedStatements to get and set data in the database.
At the end, make sure, the connection will be closed, otherwise data can be lost.
Hope that will help you a little bit

  • How to connect to  Oracle database from webdynprojava application

    Hi
    How to connect to  Oracle database from webdynprojava application. where can we provide the code to connect to database.?
    Thank You.

    Hi,
    You need to create  Java Bean model. The bean is a typical java bean with default constructor, getter and setter. You can have additional methods for query etc. The attributes in the class will be your model node and attributes.
    However you need to configure the connection and create JNDI using visual administrator before writing the code.
    You can also consider writing Session EJB with oracle and using them in WD.

    download the JDBC driver and read the docs.
    if you don't know JDBC, Google for "Sun JDBC tutorial" and study it.

    To configure Oracle JDBC:
    1. Add Oracle JDBC JAR file classes12.zip or ojdbc14.zip to classpath.
    2. Load and register the JDBC driver.
    Class.forName("oracle.jdbc.driver.OracleDriver");
    3. Obtain a connection:
    String url="jdbc:oracle:thin:@<host>:1521:<database>
    Connection con = DriverManager.getConnection(url,
    "myLogin", "myPassword");
    4. Create a SQL statement.
    Statement stmt = con.createStatement();
    5. Obtain a result set.

  • Power Query Update breaks connection to PostgreSQL database

    After the update to Power Query 2.11.3625.144, we can't connect our PostgreSQL database anymore. 
    Error message is: 
    DataSource.NotFound: PostgreSQL: Unable to find a database provider with invariant name 'Npgsql'.
    This error may have been the result of provider-specific client software being required but missing on this computer.  To download client software for this provider, visit the following site and choose at minimum 'Npgsql version 2.0.12': http://go.microsoft.com/fwlink/?LinkID=282716
    Readding the Npgsql driver doesn't solve the issue. Has the version requirement changed with the Power Query update? Or is PostgreSQL connectivity completely broken?

    Hmm, 
    If I add the line, I get the following error message in Power Query: 
    'Npgsql' returned the error: 'Unrecognized element. (C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\machine.config line 169)'.
    This error may have been the result of provider-specific client software being required but missing on this computer.  To download client software for this provider, visit the following site and choose at minimum 'Npgsql version 2.0.12': http://go.microsoft.com/fwlink/?LinkID=282716
    The code in the machine config looks like this: 
      <system.data>
            <DbProviderFactories />
            <add description=".Net Framework Data Provider for Postgresql Server" type="Npgsql.NpgsqlFactory, Npgsql, Version=2.0.12.0, Culture=neutral, PublicKeyToken=5d8b90d52f46fda7" name="Npgsql Data Provider" invariant="Npgsql" support="FF"/>
        </system.data>
    The node seems to be empty by default. Can it be that the surrounding stuff has to be differently written in that case?

  • How do connect to Historical Databases?

    Hi,
      please explain me what is Historical databases?
    Can u tell me how to connect to Historical databases? can we download these Database servers from net?
    - senthil

    Hi Senthil,
    You can try for RTXHDB (RTX Historical Database).
    RTX provide secured relational databases for LAN and WAN network.
    Often the use of relational database, or transaction-oriented technology, for off process historical LAN/WAN database applications, and doing unconventional operations on data.
    As an example,  It is in this area of off process historical data warehousing and retrieval that the RTXHDB (RTX Historical Database) system excels. RTXHDB processes and stores a massive flow of data for LAN/WAN database applications, which then can be retrieved with a great deal of speed and quickly turned into useful information for the PC user.
    You can check following links for more information.

    EdStevens, thanks for your quick answer, sorry for my explain was doesn't clear, i open oracle sql developer and choose new connection i set connection name system_orcl username:system password:*i set my password that i create when i setup database*
    -Now the link that i got after finish install database is https://Ahmed-HP:1158/em so i have question about this point Hostname and port if the link to access database is this https://Ahmed-HP:1158/em so this mean i typing at Hostname:localhost and port:1158 ?
    because the message when i test connection always is filed and I'm sure i typing username and password and SID:orcl as i set when install database.port 1158 is what the dbcontrol (Oracle Enterprise Manager) is listening on. OEM is NOT the database. As far as the database is concerned, OEM is "just another client".
    Actually, the database doesn't listen for requests on any port. There is another process, the "listener" that listens for requests to connect to the database. Typically, it listens on port 1521. You should have a tnsnames.ora file set up to resolve a connection request to the correct host. You can read more on this at http://edstevensdba.wordpress.com/2011/02/09/sqlnet_overview/

  • How to connect Java Application with database!

    Dear all, now I am create a dababase application. My database use JData Store. But I don't know how to connect application with it. Can you tell me this proplem?
    Thank!

    Do a google search for JDBC, or go buy a book.
    You will need a JDBC driver which supports your database. Or you might be able to use the JDBC-ODBC bridge if there's an ODBC driver for your database.
