awswrangler.athena.start_query_execution(sql: str, database: Optional[str] = None, s3_output: Optional[str] = None, workgroup: Optional[str] = None, encryption: Optional[str] = None, kms_key: Optional[str] = None, params: Optional[Dict[str, Any]] = None, boto3_session: Optional[boto3.session.Session] = None, data_source: Optional[str] = None) Any

Start a SQL Query against AWS Athena.


Create the default Athena bucket if it doesn’t exist and s3_output is None. (E.g. s3://aws-athena-query-results-ACCOUNT-REGION/)


This function has arguments which can be configured globally through wr.config or environment variables:

  • database

  • workgroup

Check out the Global Configurations Tutorial for details.

  • sql (str) – SQL query.

  • database (str, optional) – AWS Glue/Athena database name.

  • s3_output (str, optional) – AWS S3 path.

  • workgroup (str, optional) – Athena workgroup.

  • encryption (str, optional) – None, ‘SSE_S3’, ‘SSE_KMS’, ‘CSE_KMS’.

  • kms_key (str, optional) – For SSE-KMS and CSE-KMS , this is the KMS key ARN or ID.

  • params (Dict[str, any], optional) – Dict of parameters that will be used for constructing the SQL query. Only named parameters are supported. The dict needs to contain the information in the form {‘name’: ‘value’} and the SQL query needs to contain :name;. Note that for varchar columns and similar, you must surround the value in single quotes.

  • boto3_session (boto3.Session(), optional) – Boto3 Session. The default boto3 session will be used if boto3_session receive None.

  • data_source (str, optional) – Data Source / Catalog name. If None, ‘AwsDataCatalog’ will be used by default.


Query execution ID

Return type



Querying into the default data source (Amazon s3 - ‘AwsDataCatalog’)

>>> import awswrangler as wr
>>> query_exec_id = wr.athena.start_query_execution(sql='...', database='...')

Querying into another data source (PostgreSQL, Redshift, etc)

>>> import awswrangler as wr
>>> query_exec_id = wr.athena.start_query_execution(sql='...', database='...', data_source='...')
