Clickhouse将json数据插入字符串列

Question

We need to insert data from postgres to clickhouse. One of the field in postgres has json type. In clickhouse this field has Nullable(String) type. For inserting data we use Airflow ClickHouse Plugin :

 data = postgress_hook.get_records(query)     
 clickhouse_hook.run(
                    sql="INSERT INTO "+ self.clickhouse_tgt_table +" values",
                    parameters=data
 )

But we have an error during inserting:

'dict' object has no attribute 'encode'

What clickhouse type should we use to store json data?

Answer 1

'dict' object has no attribute 'encode'

this message is not from CH server, but from a python driver.
