如何用Java编写SQL查询从雪花中获取数据

import java.sql.*;

public class SnowflakeExample {
    public static void main(String[] args) {
        String url = "jdbc:snowflake://accountName.snowflakecomputing.com";
        String user = "username";
        String password = "password";
        
        Connection conn = null;
        Statement stmt = null;
        ResultSet rs = null;
        
        try {
            // 连接到雪花数据库
            conn = DriverManager.getConnection(url, user, password);

            // 创建Statement对象
            stmt = conn.createStatement();
            
            // 编写SQL查询语句
            String sql = "SELECT * FROM table_name";
            
            // 执行查询
            rs = stmt.executeQuery(sql);
            
            // 遍历查询结果集
            while (rs.next()) {
                // 处理每一行数据
                String column1 = rs.getString("column1");
                int column2 = rs.getInt("column2");
                
                // 输出结果
                System.out.println("column1: " + column1 + ", column2: " + column2);
            }
        } catch (SQLException e) {
            e.printStackTrace();
        } finally {
            // 关闭资源
            try { rs.close(); } catch (Exception e) { }
            try { stmt.close(); } catch (Exception e) { }
            try { conn.close(); } catch (Exception e) { }
        }
    }
}
