Clickhouse执行报错（Double-distributed IN/JOIN subqueries is denied (distributed_product_mode = ‘deny‘)）

错误示例：

DB::Exception: Double-distributed IN/JOIN subqueries is denied (distributed_product_mode = 'deny'). You may rewrite query to use local tables in subqueries, or use GLOBAL keyword, or set distributed_product_mode to suitable value. (version 20.1.4.14 (official build))

　　主要就是不支持分布式子查询而报错。

解决方案：

1、将inner join 改成 global join

2、添加配置：set distributed_product_mode = 'global';
