Inserting Date Values

Inserting Date Values

Sometimes as the part of programing requirement, we have to insert and retrieve Date like DOB, DOJ, DOM etc. with respect to database.

It is not recommended to maintain date values in the form of String, because comparisons will become difficult. In Java we have two Date classes

  1. java.util.Date
  2. java.sql.Date.

java.sql.Date is the child class of java.util.Date.

java.sql.Date is specially designed class for handling Date values wrt database. Other than database operations, if we want to represent Date in our java program then we should go for java.util.Date. java.util.Date can represent both Date and Time where as java.sql.Date represents only Date but not time.

public class DateTest { 
   public static void main(String[] args) { 
      java.util.Date udate = new java.util.Date();
      System.out.println("Util Date : "+ udate);
      long l = udate.getTime(); 
      java.sql.Date sdate = new java.sql.Date(l);
      System.out.println("SQL Date : "+ sdate); 


Util Date : Thu Nov 15 09:15:39 IST 2018
SQL Date : 2018-11-15


In sql package Time class is availble to represent Time values and TimeStamp class is available to represent both Date and Time.

Inserting Date Values into Database

Various databases follow various styles to represent Date.


Oracle: dd-MMM-yy 15-NOV-18
MySQL : yyyy-mm-dd 2018-11-15

If we use simple Statement object to insert Date values then we should provide Date value in the database supported format,which is difficult to the programmer.

If we use PreparedStatement,then we are not required to worry about database supported form, just we have to call

pst.setDate (2, java.sql.Date);

This method internally converts date value into the database supported format. Hence it is highly recommended to use PreparedStatement to insert Date values into database.

Steps to insert Date value into Database


create table users(name varchar2(10), dob date);

1. Read Date from the end user(in String form)

System.out.println("Enter DOB(dd-mm-yyyy):");
String dob =;

2. Convert date from String form to java.util.Date form by using SimpleDateFormat object.

SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy"); 
java.util.Date udate = sdf.parse(dob);

3. convert date from java.util.Date to java.sql.Date

long l = udate.getTime(); 
java.sql.Date sdate = new java.sql.Date(l);

4. set sdate to query

pst.setDate(2, sdate);
import java.sql.*;
import java.util.*;
import java.text.*;

      String sqlQuery = "insert into users values(?,?)"; 
      PreparedStatement pst = con.prepareStatement(sqlQuery); 
      int rowCount = pst.executeUpdate(); 
      if(rowCount == 0) 
         System.out.println("Record Not inserted"); 
         System.out.println("Record inserted");
