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:
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.
