In this Code Snippetswe 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...");
Java delete
