FetchAuthTokenInterface

A credentials fetcher instance.

↳ httpHandler
callable

A handler used to deliver Psr7 requests. Only valid for requests sent over REST.

↳ keyFile
array

The contents of the service account credentials .json file retrieved from the Google Developer's Console. Ex: json_decode(file_get_contents($path), true) .

↳ keyFilePath
string

The full path to your service account credentials .json file retrieved from the Google Developers Console.

↳ requestTimeout
float

Seconds to wait before timing out the request. Defaults to 0 with REST and 60 with gRPC.

↳ retries
int

Number of retries for a failed request. Defaults to 3 .

↳ scopes
array

Scopes to be used for the request.

↳ quotaProject
string

Specifies a user project to bill for access charges associated with the request.

↳ returnInt64AsObject
bool

If true, 64 bit integers will be returned as a Google\Cloud\Core\Int64 object for 32 bit platform compatibility. Defaults tofalse.

↳ location
string

If provided, determines the default geographic location used when creating datasets and managing jobs. Please note: This is only required for jobs started outside of the US and EU regions. Also, if location metadata has already been fetched over the network it will take precedent over this setting (by calling Google\Cloud\BigQuery\Table::reload() , for example).

query

Returns a BigQuery job configuration.

The job configuration is passed to either Google\Cloud\BigQuery\BigQueryClient::runQuery() or Google\Cloud\BigQuery\BigQueryClient::startQuery() . A configuration can be built using fluent setters or by providing a full set of options at once.

Unless otherwise specified, all configuration options will default based on the query job configuration except for configuration.query.useLegacySql , which defaults to false in this client.

Example:

 $queryJobConfig = $bigQuery->query(
    'SELECT commit FROM `bigquery-public-data.github_repos.commits` LIMIT 100'
); 
 // Set create disposition using fluent setters.
$queryJobConfig = $bigQuery->query(
    'SELECT commit FROM `bigquery-public-data.github_repos.commits` LIMIT 100'
)->createDisposition('CREATE_NEVER'); 
 // This is equivalent to the above example, using array configuration
// instead of fluent setters.
$queryJobConfig = $bigQuery->query(
    'SELECT commit FROM `bigquery-public-data.github_repos.commits` LIMIT 100',
    [
        'configuration' => [
            'query' => [
                'createDisposition' => 'CREATE_NEVER'
            ]
        ]
    ]
); 
 // Set a region to run the job in.
$queryJobConfig = $bigQuery->query(
    'SELECT name FROM `my_project.users_dataset.users` LIMIT 100'
)->location('asia-northeast1');
