Moving through the result set, you might want to know in what row is the current cursor positioned. To get this information, you can call the ResultSet’s getRow() method.
package org.kodejava.jdbc;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class ScrollableGetRowExample {
private static final String URL = "jdbc:mysql://localhost/kodejava";
private static final String USERNAME = "kodejava";
private static final String PASSWORD = "s3cr*t";
public static void main(String[] args) {
try (Connection connection =
DriverManager.getConnection(URL, USERNAME, PASSWORD)) {
Statement statement = connection.createStatement(
ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY);
String sql = "SELECT id, code, name, price FROM product";
ResultSet resultSet = statement.executeQuery(sql);
while (resultSet.next()) {
String code = resultSet.getString("code");
// By calling the getRow() method of the result set, we
// know what is the current row in the result set that
// we are reading the data from.
int row = resultSet.getRow();
System.out.println(row + ". " + code);
}
} catch (SQLException e) {
e.printStackTrace();
}
}
}
The result of the code snippet above:
1. P0000001
2. P0000002
3. P0000003
4. P0000004
5. P0000005
