What is a JDBCRowSet?

In standard Java Database Connectivity (JDBC), working with standard ResultSet objects often requires manually opening connections, managing statements, and tracking resource life cycles. A JDBCRowSet wraps a standard ResultSet into a JavaBean component, making database handling flexible, easy to configure, and scrollable by default.

Key Steps to Create and Use JDBCRowSet

To implement a JdbcRowSet in your Java application, you follow these straightforward steps:

• Obtain the RowSetProvider: Call RowSetProvider.newFactory() to obtain an instance of RowSetFactory.
• Create JdbcRowSet: Use rowSetFactory.createJdbcRowSet() to get your row set instance.
• Configure Connection Parameters: Set the database connection URL, username, and password using dedicated setter methods.
• Define Query & Parameters: Set the SQL statement via setCommand() and bind query placeholders with setters like setString().
• Execute and Process: Trigger execute() to load the records, iterate through the row set, and access column values smoothly.

Complete Java Code Example

import java.sql.SQLException;
import java.util.Scanner;
import javax.sql.rowset.JdbcRowSet;
import javax.sql.rowset.RowSetFactory;
import javax.sql.rowset.RowSetProvider;

public class JdbcRowSetDemo {

    public static void main(String[] args) {
        JdbcRowSetDemo demo = new JdbcRowSetDemo();
        try (Scanner scanner = new Scanner(System.in)) {
            System.out.print("Enter Country Code (e.g., IND, USA): ");
            String countryCode = scanner.next();
            demo.getCityInformation(countryCode);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public void getCityInformation(String countryCode) {
        try {
            // 1. Create RowSetFactory
            RowSetFactory factory = RowSetProvider.newFactory();

            // 2. Create JdbcRowSet instance
            try (JdbcRowSet jdbcRowSet = factory.createJdbcRowSet()) {

                // 3. Set connection properties
                jdbcRowSet.setUrl("jdbc:mysql://localhost:3306/world");
                jdbcRowSet.setUsername("root");
                jdbcRowSet.setPassword("password");

                // 4. Set SQL query command and bind parameters
                jdbcRowSet.setCommand("SELECT ID, Name, CountryCode, District, Population FROM city WHERE CountryCode = ?");
                jdbcRowSet.setString(1, countryCode);

                // 5. Execute query
                jdbcRowSet.execute();

                // 6. Iterate through the records
                while (jdbcRowSet.next()) {
                    System.out.println("ID: " + jdbcRowSet.getInt("ID"));
                    System.out.println("Name: " + jdbcRowSet.getString("Name"));
                    System.out.println("CountryCode: " + jdbcRowSet.getString("CountryCode"));
                    System.out.println("District: " + jdbcRowSet.getString("District"));
                    System.out.println("Population: " + jdbcRowSet.getInt("Population"));
                    System.out.println("------------------------------------------");
                }
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}
