Methods

__construct

Create a BigQuery client.

Parameters
Name	Description
`config`	`array` Configuration options.
`↳ apiEndpoint`	`string` The hostname with optional port to use in place of the default service endpoint. Example: `foobar.com` or `foobar.com:1234`.
`↳ projectId`	`string` The project ID from the Google Developer's Console.
`↳ authCache`	`CacheItemPoolInterface` A cache for storing access tokens. Defaults to a simple in memory implementation.
`↳ authCacheOptions`	`array` Cache configuration options.
`↳ authHttpHandler`	`callable` A handler used to deliver Psr7 requests specifically for authentication.
`↳ credentialsFetcher`	`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 to false.
`↳ 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 Table::reload(), for example).

query

Returns a BigQuery job configuration.

The job configuration is passed to either BigQueryClient::runQuery() or 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._repos.commits` LIMIT 100'
);

// Set create disposition using fluent setters.
$queryJobConfig = $bigQuery->query(
    'SELECT commit FROM `bigquery-public-data._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._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');

Parameters
