@Marvin how do I get the column names using the snowflake_query function?

To get the column names using the
snowflake_query
function in Prefect, you'll typically need to access the underlying Snowflake connection or cursor. This is because the Prefect
snowflake_query
function itself does not directly provide column names in its return values. Here's a general approach you can take: 1. Access the Snowflake Cursor: Use the Snowflake connection to execute your query and retrieve the cursor. 2. Fetch Column Names: Use the cursor's
description
attribute to get the column names. Here's a conceptual example in Python:
Copy code
python
from prefect_snowflake import SnowflakeConnector

# Replace with your actual credentials and query
credentials = {"your_credentials_here"}
query = "SELECT * FROM your_table"

with SnowflakeConnector(credentials) as conn:
    cursor = conn.cursor()
    cursor.execute(query)
    column_names = [desc[0] for desc in cursor.description]
    print(column_names)
This example assumes you have set up your Snowflake credentials correctly and installed the
prefect-snowflake
package. For more details, you can refer to the Prefect Snowflake documentation. If you need more specific help with the
snowflake_query
function itself, you may want to look into how to access the cursor directly through the Prefect Snowflake integration.
