public class JDBCDeleteExample {
public static void main(String[] args) throws SQLException {
Connection con = null; // connection reference variable for getting
// connection
Statement stmt = null; // Statement reference variable for query
// Execution
String conUrl = "jdbc:mysql://192.168.10.13:3306/";
String driverName = "com.mysql.jdbc.Driver";
String databaseName = "student";
String usrName = "root";
String usrPass = "root";
try {
// Loading Driver
Class.forName(driverName);
} catch (ClassNotFoundException e) {
System.out.println(e.toString());
}
try {
// Getting Connection
con = DriverManager.getConnection(conUrl + databaseName, usrName,
usrPass);
// Creating Statement for query execution
stmt = con.createStatement();
// creating Query String
String query = "DELETE FROM student WHERE RollNo=1";
// Updating Table
stmt.executeUpdate(query);
System.out.println("Record deleted Successfully....");
} catch (Exception e) {
