删除最后一天的记录

Question

如何从表

Parse.Cloud.job("deleteOldEntries", function(request, status) { 
      var GameScore = Parse.Object.extend("GameScore"); 
      var query = new Parse.Query(GameScore); 
      var day = new Date(); 
      day.setDate(day.getDate()-1); 

      query.lessThan("createdAt", day); 

      query.find({ 
         success:function(results) { 
         console.log(results); 
         for (var i = 0, len = results.length; i < len; i++) { 
         var result = results[i]; 

         result.destroy({}); 
         console.log("Destroy: "+result); 

         } 
         status.success("Delete successfully.");    
         }, 
         error: function(error) { 
         status.error("Uh oh, something went wrong."); 
         console.log("Failed!");   
         } 
         }) 

      });

Parse.Cloud.job("deleteMessages", function(request, status) { 

Parse.Cloud.useMasterKey(); 

var ts = Math.round(new Date().getTime()/1000); 
var tsYesterday = ts - (24 * 3600); 
var dateYesterday = new Date(tsYesterday*1000); 

var query = new Parse.Query("Your Object Class"); 

query.lessThan("createdAt", dateYesterday); 

query.find({ 
    success: function(result) { 
     for(var i=0; i<result.length; i++) { 
      result[i].destroy({ 
       success: function(object) { 
        status.success("Delete job completed"); 
        alert('Delete Successful'); 
       }, 
       error: function(object, error) { 
        status.error("Delete error :" + error); 
        alert('Delete failed'); 
       } 
      }); 
     } 
     status.success("Delete job completed"); 
    }, 
    error: function(error) { 
     status.error("Error in delete query error: " + error); 
     alert('Error in delete query'); 
    } 
}); 
});
