More elegant way to insert empty java.sql.Date in MySQL Database?

MySQLMySQLi Database

Let us first create a table. Following is the query to create a table in database ‘web’ −

mysql> create table DemoTable
(
   AdmissionDate date
);
Query OK, 0 rows affected (0.53 sec)

Here is the Java code to insert empty(NULL) java.sql.Date in MySQL DB −

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
public class InsertNullDateDemo{
   public static void main(String[] args){
      Connection con=null;
      PreparedStatement ps=null;
      try{
         con=DriverManager.getConnection("jdbc:mysql://localhost:3306/web?useSSL=false", "root","123456");
         String query="insert into DemoTable(AdmissionDate) values(?) ";
         ps= con.prepareStatement(query);
         ps.setNull(1, java.sql.Types.DATE);
         ps.executeUpdate();
         System.out.println("check the table......");
      }
      catch(Exception e){
         e.printStackTrace();
      }
   }
}

The snapshot of Java code is as follows −


This will produce the following output −

Let us now check records from the same table. The snapshot is as follows displaying empty date we successfully inserted −
