# This workflow demonstrates how to use the BigQuery connector:
# Create a dataset and then insert a table with data from a public dataset
# Delete both the table and dataset
# Expected output: "SUCCESS"
- init:
    assign:
      - project_id: ${sys.get_env("GOOGLE_CLOUD_PROJECT_ID")}
      - dataset_id: "example_dataset"
      - table_id: "example_table"
      - query: "SELECT * FROM `bigquery-public-data.usa_names.usa_1910_2013` LIMIT 5000;"
      - create_disposition: "CREATE_IF_NEEDED"  # creates table if it doesn't exist
      - write_disposition: "WRITE_TRUNCATE"  # truncates table if it already exists
- create_dataset:
    call: googleapis.bigquery.v2.datasets.insert
    args:
      projectId: ${project_id}
      body:
