Bigquery PHP populate table with insert select job - php

Question

I'm trying to populate a previously created table from an insert select job in PHP.
Google documentation has a short paragraph that say the next:
"Run an asynchronous query, pass in the name of your existing table, and set writeDisposition=WRITE_APPEND."
Now I'm getting rows from bigquery using next sentences :
// query request service
$query = new Google_Service_Bigquery_QueryRequest();
//armar query
$selectQuery = "select source_year, year, month, day from publicdata:samples.natality LIMIT 100";
if($whereQuery!=null && strlen($whereQuery)>0)$selectQuery = $selectQuery . " WHERE " . $whereQuery;
//print_r(var_dump($selectQuery));
$query->setQuery($selectQuery);
$response = $service->jobs->query($project_id, $query);
$jsonStr = "";
if($response)if($response->getRows())$jsonStr = $response->getRows();
print_r($jsonStr);
But I need to populate another table from the query result.
Thank you for your advices.
Bye
Thank you Pentium10 but I'm receiving the error message "Call to undefined method Google_Service_Bigquery_QueryRequest::setDestinationTable() " because I'm not using a job to execute the query.
I working with the next sentences to get the query result but Its didn't work:
//query request service
$query = new Google_Service_Bigquery_QueryRequest();
//destination table
$destinationTable = new Google_Service_Bigquery_TableReference();
$destinationTable->setDatasetId($dataset);
$destinationTable->setProjectId($project_id);
$destinationTable->setTableId('ventastest');
$query->setDestinationTable($destinationTable);
$query->setWriteDisposition('WRITE_APPEND');
//build query
$selectQuery = "SELECT " . $fieldsQuery . " FROM " . $dataset . "." . $tableQuery;
if($whereQuery!=null && strlen($whereQuery)>0)$selectQuery = $selectQuery . " WHERE " . $whereQuery;
$query->setQuery($selectQuery);
$response = $service->jobs->query($project_id, $query);
$jsonStr = "";
if($response)if($response->getRows())$jsonStr = $response->getRows();
print_r($jsonStr);
Even if I attach to the service->job I receive the error message:
$destinationTable = new Google_Service_Bigquery_TableReference();
$destinationTable->setDatasetId($dataset);
$destinationTable->setProjectId($project_id);
$destinationTable->setTableId('ventastest');
$service->jobs->setDestinationTable($destinationTable);
$service->jobs->setWriteDisposition('WRITE_APPEND');
Thanks and bye!

Answer 1

$destinationTable = new Google_Service_Bigquery_TableReference();
$destinationTable->setDatasetId(DATASET_ID);
$destinationTable->setProjectId(PROJECT_ID);
$destinationTable->setTableId('name_of_the_table');
$queryConfig->setDestinationTable($destinationTable);
$queryConfig->setWriteDisposition('WRITE_APPEND');
