Delete records from database using JDBC

In this blog we will know how to delete records from database using JDBC (Java Database Connectivity) in console window.


Here we use Type-1 driver (JDBC-ODBC bridge)


Creation of dsn(database source name) for Oracle


Start-Control panel- Administrative Tools- Data Sources (ODBC)-go to system dsn tab-click add button-select a driver for which you want to set up data source (for Oracle- Oracle in XE)-select it and click finish-give any name in data source name textbox-then click ok button.


Note: - Here Username=system, Password=pintu and Dsn name=dsn1


Table Creation

Create table employee (empno int,empname varchar(50),sal int)


Example:- To delete record from a table


/*To delete record from a table by using Statement*/

import java.sql.*;

import java.util.*;

public class delete


public static void main(String args[]) throws Exception



Scanner sc=new Scanner(;

Connection con=DriverManager.getConnection("jdbc:odbc:dsn1","system","pintu");

Statement stmt=con.createStatement();

System.out.print("Enter lower limit salary: ");

int lb=sc.nextInt();

System.out.print("Enter upper limit salary: ");

int ub=sc.nextInt();

String sql="delete from employee where sal between "+lb+" and "+ub;

int no=stmt.executeUpdate(sql);

System.out.println(no +" Records Successfully Deleted...");
