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