Binding data in type (dict) is not supported

Question

I am trying to write json object into a particular column of my sql table

variant_str = response.json()

print(con.cursor().execute('INSERT INTO TEST_TABLE (JSON_STR) VALUES (?)', (variant_str,)))

Here, the variant_str is of type dict.

I get an error that:

snowflake.connector.errors.ProgrammingError: 252004: Failed processing pyformat-parameters; 255001: Binding data in type (dict) is not supported.

The table's ddl where I am trying to load the data is this:

create or replace TABLE TEST_TABLE (
    JSON_STR VARIANT
);

Answer 1

It is possible to use ? as the placeholder for parameter binding:

import snowflake.connector

snowflake.connector.paramstyle='qmark'

Insert using INSERT INTO ... SELECT PARSE_JSON(...)

con.cursor().execute('INSERT INTO TEST_TABLE (JSON_STR) SELECT PARSE_JSON(?)'
                     , (variant_str))

where variant_str is a valid JSON string
