[jitendra rawat]

This is the script I have written in adword script writer but this script not give any row in the query, But when i was running report for campaign performance then it will give data.

this script not giving me any row in query

function main(){

  var report = AdWordsApp.report("Select CampaignName,Clicks,Impressions,Cost From CAMPAIGN_PERFORMANCE_REPORT DURING LAST_7_DAYS");

var rows = report.rows();

   while (rows.hasNext()) {

    var row = rows.next();

    var campaignName = row['CampaignName'];

    var clicks = row['Clicks'];

    var impressions = row['Impressions'];

    var cost = row['Cost'];

    Logger.log(campaignName + ',' + clicks + ',' + impressions + ',' + cost);

  }

}

So please give me hint or script how I can get same data for campaign performance report in my script.
