Return ArrayCollection from SELECT query - actionscript-3

Question

In my AIR app i am trying to get the names from sqlite database as an ArrayCollection . Here is my code.
private function visitorName():void {
var sqlText:String = "SELECT name FROM user";
visitorNames = new SQLStatement;
visitorNames.sqlConnection = dbConn;
visitorNames.addEventListener(SQLEvent.RESULT, visitornamesResult);
visitorNames.addEventListener(SQLErrorEvent.ERROR, errorHandler);
visitorNames.text = sqlText;
visitorNames.execute();
}
private function visitornamesResult(event:SQLEvent):Array {
var result:SQLResult = visitorNames.getResult();
var namesList:Array = new Array();
namesList = result.data;
datafield3.dataProvider = namesList;
return namesList;
}
What should i do to get the results to an ArrayCollection by calling the visitorName() function?
Is it possible to get return value from a nested function?I know the visitorName function should be changed to ArrayCollection type and should declare an ArrayCollection variable inside it .. but not so sure how to proceed .. any help appreciated ..

Answer 1

First of all, notice that visitornamesResult is an event handler, so you won't be able to get the return value of that function.
You will want to actually put the result somewhere when you get it (in the UI? or in a model?)
Let's keep it simple, and just assign it to your datafield3.dataProvider:
private function visitorName(): { ... /* same as before */ }
private function visitornamesResult(event:SQLEvent):void {
var result:SQLResult = visitorNames.getResult();
// this is how you create an ArrayCollection with a provided Array
var visitors: ArrayCollection = new ArrayCollection( result.data );
datafield3.dataProvider = visitors;
}
