class google.cloud.bigquery.enums.KeyResultStatementKind()

https://cloud.google.com/bigquery/docs/reference/rest/v2/Job#keyresultstatementkind

FIRST_SELECT( = 'FIRST_SELECT )

KEY_RESULT_STATEMENT_KIND_UNSPECIFIED( = 'KEY_RESULT_STATEMENT_KIND_UNSPECIFIED )

class google.cloud.bigquery.enums.QueryApiMethod(value)

API method used to start the query. The default value is INSERT.

INSERT( = 'INSERT )

Submit a query job by using the jobs.insert REST API method.

This supports all job configuration options.

QUERY( = 'QUERY )

Submit a query job by using the jobs.query REST API method.

Differences from INSERT:

  • Many parameters and job configuration options, including job ID and destination table, cannot be used with this API method. See the jobs.query REST API documentation for the complete list of supported configuration options.

  • API blocks up to a specified timeout, waiting for the query to finish.

  • The full job resource (including job statistics) may not be available. Call reload() or get_job() to get full job statistics and configuration.

  • query() can raise API exceptions if the query fails, whereas the same errors don’t appear until calling result() when the INSERT API method is used.

class google.cloud.bigquery.enums.WriteDisposition()

Specifies the action that occurs if destination table already exists.

The default value is WRITE_APPEND.

Each action is atomic and only occurs if BigQuery is able to complete the job successfully. Creation, truncation and append actions occur as one atomic update upon job completion.

WRITE_APPEND( = 'WRITE_APPEND )

If the table already exists, BigQuery appends the data to the table.

WRITE_EMPTY( = 'WRITE_EMPTY )

If the table already exists and contains data, a ‘duplicate’ error is returned in the job result.
