What is a RowSet object explain using a JDBC program?

JDBCMySQLMySQLi DatabaseJava 8

A RowSet is a wrapper around a ResultSet Object. It can be connected, disconnected from the database and can be serialized. It maintains a JavaBean component by setting the properties. You can pass a RowSet object over the network. By default, RowSet object is scrollable and updatable and it is used to make a ResultSet object scrollable and updatable.

You Can get a RowSet using the

RowSetProvider.newFactory().createJdbcRowSet() method.

Example

Assume we have a table named dataset in the database as:

+--------------+-----------+
| mobile_brand | unit_sale |
+--------------+-----------+
| Iphone       |      3000 |
| Samsung      |      4000 |
| Nokia        |      5000 |
| Vivo         |      1500 |
| Oppo         |       900 |
| MI           |      6400 |
| MotoG        |      4360 |
| Lenovo       |      4100 |
| RedMi        |      4000 |
| MotoG        |      4360 |
| OnePlus      |      6334 |
+--------------+-----------+

Following JDBC example creates a RowSet object retrieves the contents of the table named dataset using this object:

import java.sql.DriverManager;
import javax.sql.RowSet;
import javax.sql.rowset.RowSetProvider;
public class RowSetExample {
   public static void main(String args[]) throws Exception {
      //Registering the Driver
      DriverManager.registerDriver(new com.mysql.jdbc.Driver());
      //Creating the RowSet object
      RowSet rowSet = RowSetProvider.newFactory().createJdbcRowSet();
      //Setting the URL
      String mysqlUrl = "jdbc:mysql://localhost/TestDB";
      rowSet.setUrl(mysqlUrl);
      //Setting the user name
      rowSet.setUsername("root");
      //Setting the password
      rowSet.setPassword("password");
      //Setting the query/command
      rowSet.setCommand("select * from Dataset");
      System.out.println("Contents of the table");
      while(rowSet.next()) {
         System.out.print("Brand: "+rowSet.getString(1)+", ");
         System.out.print("Sale: "+rowSet.getString(2));
         System.out.println("");
      }
   }
}

Output

Contents of the table
Brand: Iphone, Sale: 3000
Brand: Samsung, Sale: 4000
Brand: Nokia, Sale: 5000
Brand: Vivo, Sale: 1500
Brand: Oppo, Sale: 900
Brand: MI, Sale: 6400
Brand: MotoG, Sale: 4360
Brand: Lenovo, Sale: 4100
Brand: RedMi, Sale: 4000
Brand: MotoG, Sale: 4360
Brand: OnePlus, Sale: 6334
