JDBC Insert Records Using PreparedStatement

The post (“JDBC Insert Records Using PreparedStatement”) will give an example, and show how to add records using PreparedStatement. JDBC Prepared Statement is used to handle precompiled query. If you want to execute a Statement object many times, it usually reduces execution time to use a PreparedStatement object instead.

Example:


package net.tecbar.jdbc.examples;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class JdbcInsertRecordExample2 {
    private final static String USERNAME = "deploy";
    private final static String PASSWORD = "Ts78W$k";

	public static void main(String[] args) {
	   Connection conn = null;
	   PreparedStatement stmt = null;
	   
	   final String sql = "INSERT INTO category (id, name, description) VALUES (?,?,?)";
	   
	   try{
	      // Register JDBC driver
	      Class.forName("com.mysql.jdbc.Driver");
	      // Open a connection
	      conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/mytecbar", USERNAME, PASSWORD);
	      
	      // add one record
	      stmt = conn.prepareStatement(sql);
	      stmt.setInt(1, 1);
	      stmt.setString(2, "book");
	      stmt.setString(3, "there are 50,000 volumes available");
	      stmt.executeUpdate();
	      
	      // add next record
	      stmt.setInt(1, 2);
	      stmt.setString(2, "movies");
	      stmt.setString(3, "31,000 movies are available");
	      stmt.executeUpdate();
	   } catch(SQLException se){
			// process exception here
		   se.printStackTrace();
	   } catch(Exception e){
			// process exception here
		   e.printStackTrace();
	   } finally{
		   release(conn, stmt, null);
	   }
	}
	
	public static void release(Connection conn, Statement stmt, ResultSet rs) {
		try {
			if (rs != null) {
				rs.close();
			}
			if (stmt != null) {
				stmt.close();
			}
			if (conn != null) {
				conn.close();
			}
		} catch (SQLException ex) {
			// process exception here
		}
	}
	
}

}

public static void release(Connection conn, Statement stmt, ResultSet rs) {

try {

rs.close();

}

if (stmt != null) {

stmt.close();

}

if (conn != null) {

}

} catch (SQLException ex) {

// process exception here

Howdy! Quick question that’s totally off topic. Do you know how
to make your site mobile friendly? My site looks weird when browsing from
my iphone 4. I’m trying to find a theme or plugin that might be
able to resolve this issue. If you have any recommendations, please
share. Cheers!
