Java Database Connectivity (JDBC) supports ODBC-based databases and provides a independent database.

JDBC has four primary pieces, used for each database access phase:

• DriverManager: the DriverManager class loads and configures a database driver on the database
• Connection: the Connection class performs confectioning and authentication to a database

CODE

getConnection(String url)
getConnection(String url, Properties info)
getConnection(String url, String eXceed, String 12345)

The usual password and username of a database especially the oracle

CODE

Connection conn = DriverManager.getConnection( "jdbc:oracle:thin:@mydbserver:1521:mysid","scott", "tiger" );

• Statement / PreparedStatement: the Statement and PreparedStatement classes send SQL statements to the database engine for preprocessing and eventually execution

CODE

Statement createStatement()
Statement createStatement(int resultSetType, int resultSetConcurrency)

…..

CODE

PreparedStatement prepareStatement(String sql)
PreparedStatement prepareStatement(String sql,
int resultSetType, int resultSetConcurrency)

• ResultSet: the ResultSet class allows for the inspection of results from executions

CODE

ResultSet rs = preparedStatement.executeQuery();

Here some sample code for you:

CODE

package com.informit.jdbc;

import java.sql.*;

public class JDBCExample {
  public static void main( String[] args ) {
   try {
     DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
     Connection conn = DriverManager.getConnection(
"jdbc:oracle:thin:@mydbserver:1521:mysid",
                            "exceed", "12345" );

     // Create a Statement
     PreparedStatement ps = conn.prepareStatement(
"SELECT state FROM HomePage WHERE name = ?" );
     ps.setString( 1, "Ronald" );

     ResultSet rs = ps.executeQuery();
     // Iterate through the result and print the employee names
     while (rs.next ()) {
      System.out.println( "State: " + rs.getString( "state" ) );
     }
   }
   catch( Exception e ) {
     e.printStackTrace();
   }
  }
}
