How to convert a Date object in to Timestamp in JDBC program?

The getTime() method of the java.sql.Date class retrieves and returns the time from the current timestamp in milliseconds (long) from epoch time 1, 1970 00:00:00.000 GMT.

//Retrieving the date
Date date = rs.getDate("Dispatch_Date");

The constructor of the java.sql.Timestamp class accepts a long variable representing the time in milliseconds from the epoch time and constructs the Timestamp object.

//Creating a Timestamp object.
Timestamp ts = new Timestamp(date.getTime()));

Using these, you can convert a Date object to TimeStamp object in JDBC.

Assume we have established connection with MySQL database and created a table named dispatch_data using statement object as:

Assume we have established connection with MySQL database and created a table named dispatch_data using statement object as:

//Creating a Statement object
Statement stmt = con.createStatement();

//Query to create a table
String create_query = "Create table dispatch_data ("
   + "Product_Name VARCHAR(255), "
   + "Name_Of_Customer VARCHAR(255) , "
   + "Dispatch_Date date, "
   + "Location VARCHAR(255) )";
System.out.println("table created......");

We have populated the table using PreparedStatement as:

//Inserting values to a table
String query = "INSERT INTO dispatch_data VALUES (?, ?, ?, ?)";
PreparedStatement pstmt = con.prepareStatement(query);

pstmt.setString(1, "KeyBoard");
pstmt.setString(2, "Amith");
pstmt.setDate(3, new Date(376401869000L));
pstmt.setString(4, "Hyderabad");

pstmt.setString(1, "Ear phones");
pstmt.setString(2, "Sumith");
pstmt.setDate(3, new Date(356788333000L));
pstmt.setString(4, "Vishakhapatnam");

pstmt.setString(1, "Mouse");
pstmt.setString(2, "Sudha");
pstmt.setDate(3, new Date(594733933000L));
pstmt.setString(4, "Vijayawada");

System.out.println("Records inserted......");

Following JDBC program retrieves the date values from the ResultSet converts into Timestamp object and prints the details.

import java.sql.Connection;
import java.sql.Date;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;
import java.sql.Timestamp;
public class DateToTimeStamp {
   public static void main(String args[])throws Exception {
      //Registering the Driver
      DriverManager.registerDriver(new com.mysql.jdbc.Driver());
      //Getting the connection
      String mysqlUrl = "jdbc:mysql://localhost/mydatabase";
      Connection con = DriverManager.getConnection(mysqlUrl, "root", "password");
      System.out.println("Connection established......");
      //Creating a Statement object
      Statement stmt = con.createStatement();
      //Creating Statement object
      stmt = con.createStatement();
      ResultSet rs = stmt.executeQuery("select * from dispatch_data");
      //Retrieving values
      while( {
         System.out.println("Product Name: "+rs.getString("Product_Name"));
         System.out.println("Name Of The Customer: "+rs.getString("Name_Of_Customer"));
         //Retrieving the date
         Date date = rs.getDate("Dispatch_Date");
         //Printing the time of dispatch
         System.out.println("Dispatch_Timestamp: "+new Timestamp(date.getTime()));


Connection established......
Product Name: KeyBoard
Name Of The Customer: Amith
Dispatch_Timestamp: 1981-12-05 00:00:00.0

Product Name: Ear phones
Name Of The Customer: Sumith
Dispatch_Timestamp: 1981-04-22 00:00:00.0

Product Name: Mouse
Name Of The Customer: Sudha
Dispatch_Timestamp: 1988-11-05 00:00:00.0
