在没有Oracle依赖的Java中使用Oracle引用游标

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;

public class OracleCursorExample {
    public static void main(String[] args) {
        String url = "jdbc:oracle:thin:@localhost:1521:orcl";
        String user = "username";
        String password = "password";

        try (Connection conn = DriverManager.getConnection(url, user, password)) {
            String sql = "SELECT * FROM my_table";
            PreparedStatement pstmt = conn.prepareStatement(sql);
            ResultSet rs = pstmt.executeQuery();

            while (rs.next()) {
                // 处理结果集中的每一行数据
                System.out.println(rs.getString(1) + " " + rs.getString(2));
            }

            rs.close();
            pstmt.close();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}
