首先,我们需要将数据插入到clickhouse数据库中。为此,我们可以使用clickhouse-connector-python库提供的insert方法。下面是一个示例代码: importclickhouse_driver# 连接clickhouse数据库connection=clickhouse_driver.connect(host='localhost',port=9000,user='default',password='',database='test')# 创建一个Cursor对象curs...

2.connect fromclickhouse_driverimportconnect#账号:密码@主机名:端口号/数据库conn = connect(f'clickhouse://{user}:{pw}@{host}:9000/{database}') cursor=conn.cursor() cursor.execute('SHOW TABLES') 二、clickhouse_sqlalchemy连接方式 使用较复杂,推荐使用上述两种,注意使用端口为http端口8123。
在查bug中发现clickhouse官方出了个库叫clickhouse_connect(文档地址:https://clickhouse.com/docs/en/integrations/python),因为也没有找到原来driver的问题解决方案,一狠心就打算直接切换成connect库。在windows环境下pycharm运行都良好。但是上了linux后,多进程(我用的joblib库的multiporcess)下报错。这里提一下win和...
