AWQL result has duplicates

[Tim Johnson]

Hi, I am trying to pull unique Account,Campaign Name, & Campaign ID's using 
AWQL using PHP.  Here's the reporting part of my code:

    $reportQuery = 'SELECT AccountDescriptiveName,CampaignName,CampaignId FROM 
ADGROUP_PERFORMANCE_REPORT';
    $reportDownloader = new ReportDownloader($session);
    $reportSettingsOverride = (new ReportSettingsBuilder())
        ->includeZeroImpressions(false)
        ->skipReportHeader(TRUE)
                ->skipColumnHeader(FALSE)
                ->skipReportSummary(TRUE)
                ->SkipReportHeader(TRUE)
                ->build();
    $reportDownloadResult = 
$reportDownloader->downloadReportWithAwql($reportQuery, DownloadFormat::CSV, 
$reportSettingsOverride);
    $a =  $reportDownloadResult->getAsString();



And this is the output:


[2017-09-06 08:11:06] AW_REPORT_DOWNLOADER.INFO: 
clientCustomerId=509-496-9641 unknown (AwApi-PHP, googleads-php-lib/29.0.0, 
PHP/7.1.2, GuzzleHttp/6.2.1, curl/7.51.0) "POST 
/api/adwords/reportdownload/v201708 HTTP/1.1" Status: 200
Account,Campaign,Campaign ID
Account #1,Campaign #2,921452568
Account #1,Campaign #2,921452568
Account #1,Campaign #1,912412908
Account #1,Campaign #1,912412908 

As you can see the result is duplicated.  How do I only get back distinct 
rows?

Thank you very much for the help.

Regards
Tim
