I want to update the one record from a table with 'WHERE' clause.

I have install google/cloud-bigquery using composer for php.

My Code :

    $cloud = new ServiceBuilder([
        'keyFilePath' => 'Path for json file'
    ]);                
    $bigQuery = $cloud->bigQuery();
    $dataset = $bigQuery->dataset('mydataset');
    $table = $dataset->table('mytable');
    $rows = $table->update(['name'=>'abc']);  

My above code are not working.

I have a query

1] Is it possible with this library or not.

2] If yes, then How can i pass the WHERE Clause in above $table->update(['name'=>'abc']); code.

3] How to set the field which i want to update.
