1. 安装clickhouse_driver库 首先,你需要在你的Python环境中安装clickhouse_driver库。你可以使用pip命令来安装: pip install clickhouse-driver 1. 2. 连接到ClickHouse数据库 在开始使用clickhouse_driver之前,你需要先连接到ClickHouse数据库。你可以使用clickhouse_driver的connect()函数来建立连接: importclickhouse_drive...
一、clickhouse_driver连接的两种方式 注意端口都使用tcp端口9000 1.Client fromclickhouse_driverimportClient client= Client(host=host, port=9000, database=database,user=user ,password=pw) sql='SHOW TABLES'res= client.execute(sql) 2.connect fromclickhouse_driverimportconnect#账号:密码@主机名:端口号/数...
方法一:使用clickhouse_driver 包中的Client类,通过实例化一个客户端进行对数据库的增删改查操作 from clickhouse_driver import Client from datetime import datetime importpsutil host_name = '192.168.50.94' client = Client(host=host_name,database='default',user='default',password='自己设的密码',send_re...
因为新业务需要,数据都存储在阿里云服务器的ClickHouse数据库里,最近想取点数探索一下,于是下载了客户端工具DBeaver并成功连接ClickHouse,然后想通过python脚本来访问ClickHouse数据库,于是屁颠屁颠的装了一个clickhouse_driver模块,ip,端口,账号,密码等如下代码,折腾了半天始终不得要领,不是报102错误代码,就是209错误代码...
