import snowflake.connector
# Establish a connection to your Snowflake instance
con = snowflake.connector.connect(
user='USERNAME',
password='PASSWORD',
account='ACCOUNT_URL',
warehouse='WAREHOUSE',
database='DATABASE',
schema='SCHEMA'
)
# Execute a query
cur = con.cursor()
cur.execute("SELECT * FROM YOUR_TABLE")
# Fetch the results into a pandas dataframe
df = pd.DataFrame(cur.fetchall())
# Set the dataframe's column headers to the column names from the query
df.columns = [i[0] for i in cur.description]
In this example, cur.description
is a list of tuples, where each tuple provides metadata about one of the columns in the result set. The first item in each tuple is the column name, so [i[0] for i in cur.description]
gives you a list of all column names.
Please replace 'USERNAME', 'PASSWORD', 'ACCOUNT_URL', 'WAREHOUSE', 'DATABASE', 'SCHEMA', and 'YOUR_TABLE' with your actual Snowflake credentials and the specific table you're querying.
If you're using Prefect to orchestrate your workflows, you might be executing your Snowflake queries within a Prefect task. In that case, you would include the code to fetch the results into a pandas dataframe and set the column headers within your task function.
I hope this helps! If you have any more questions, feel free to ask.
