java impala分页

在Java中实现Impala分页查询，可以使用Impala JDBC驱动来连接Impala数据库，并执行相应的SQL语句。以下是一个示例代码，用于在Java中实现Impala分页查询：

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

public class ImpalaPagination {
    public static void main(String[] args) {
        Connection connection = null;
        Statement statement = null;
        ResultSet resultSet = null;
        
        try {
            // 连接Impala数据库
            Class.forName("com.cloudera.impala.jdbc41.Driver");
            connection = DriverManager.getConnection("jdbc:impala://localhost:21050/default");
            
            // 创建Statement对象
            statement = connection.createStatement();
            
            // 执行分页查询
            String sql = "SELECT * FROM student ORDER BY age LIMIT 10 OFFSET 0";
            resultSet = statement.executeQuery(sql);
            
            // 处理查询结果
            while (resultSet.next()) {
                // 处理每一行数据
                // ...
            }
        } catch (ClassNotFoundException | SQLException e) {
            e.printStackTrace();
        } finally {
            // 关闭资源
            try {
                if (resultSet != null) {
                    resultSet.close();
                }
                if (statement != null) {
                    statement.close();
                }
                if (connection != null) {
                    connection.close();
                }
            } catch (SQLException e) {
                e.printStackTrace();
            }
        }
    }
}
