JDBC Insert Preparedstatement


The java.sql package contain a prepared statement, This prepared statement interface is available from the Statement interface. This is used to pass parameters at runtime. In this Tutorial we want to describe you a code that helps you in understanding JDBC Insert Prepared Statement. For this we have a class Jdbc Insert Prepared statement, Inside this class we have a main method that include the list of following steps -

 import a package java.sql - this provides you a network interface that help in communicating between front end and backend in database.

  Loading a driver followed by calling a class.forname( ),this class accept a driver class as argument. The Driver Manager call getConnection (),which returns you a connection object and this is used to built a connection between url and database.

  prepareStatement ( ) : This method is useful when you want to execute the same statement object many times, This reduces the time of execution to use the same object.The method accept a sql object as parameter, that include the list of inserted values into the table set The String( ) : Set String XXX  is defined in prepared statement to substitute a value in the question  mark placeholder as string,int .In the code, we substitute a question mark value as string.executeUpdate ( ) :This method provides you the numbers of affected rows in the table and execute the statement in a given code.executeQuery ( ):This method provides you a set of records retrieved from a table in the database. The select  statement is used to obtain the records from the result set.

 next ( ) : This method  retain  you the next elements in a series.

Finally the print print the No, Name from a employee table present in database. In case there is an exception in try block, the subsequent catch block check and handle the exception.

import java.sql.*;

public class JdbcInsertPreparedstatement {

  public static void main(String args[]) {

  Connection con = null;
  PreparedStatement pst = null;
  ResultSet rs = null;

  String url = "jdbc:mysql://localhost:3306/";
  String db = "komal";
  String driver = "com.mysql.jdbc.Driver";
  String user = "root";
  String pass = "root";

  try {
  con = DriverManager.getConnection(url + db, user, pass);
  con.setAutoCommit(false);// Disables auto-commit.

  String sql = "insert into employees values(?,?,?,?) ";
  pst = con.prepareStatement(sql);



  sql = "select * from employees";
  rs = pst.executeQuery(sql);

  System.out.println("No  \tName");
  while ( {
  System.out.print(rs.getString(1) + " \t");
  System.out.print(rs.getString(2) + " \t");
  System.out.print(rs.getString(3) + " \t");

  catch (Exception e) {
