# BigQuery serviceaccount setups and SQL 

```python

def get_gcp_costs_by_sku():
    credentials = service_account.Credentials.from_service_account_file(SERVICE_ACCOUNT_PATH)
    client = bigquery.Client(credentials=credentials, project=PROJECT_ID)
		...

    sku_query = f"""
        SELECT
            sku.description AS sku_description,
            SUM(cost) AS total_cost,
            SUM(usage.amount) AS total_usage,
            ANY_VALUE(usage.unit) AS usage_unit
        FROM
            `{PROJECT_ID}.[YOUR DATASET NAME]`
        WHERE
            usage_start_time >= '{start_of_month}'
            AND usage_start_time < '{today}'
        GROUP BY
            sku_description
        HAVING
            total_cost > 100
        ORDER BY
            total_cost DESC
    """

    sku_result = client.query(sku_query).result().to_dataframe()
```
