First let us create a table. The following is the query to create a table in the database 'web':
mysql> create table DemoTable ( AdmissionDate date ); Query OK, 0 rows affected (0.53 sec)
The following is the Java code to insert an empty (NULL) java.sql.Date into the MySQL database −
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(); } } }
Snapshot of the Java code As follows:
# This will produce the following output: Now let us check the records from the same table.
