Question

I’m just trying to make a simple function that will return all the data from my SQLITE database as an array. But it looks like when my function is returning the array, the SQL statement is actually still executing… so it’s empty… Does anyone have a suggestion? Or am I just going about this whole thing wrong.

I know I could just have the event listener functions outside this function, and they could then set the data. But i’m trying to make a AS3 Class that holds all my SQL functions, and It would be nice to have everything for this particular function just in one function, so it can return an array to me.

 public function getFavsGamesArray():Array
                {
                    getFavsArraySql.addEventListener(SQLEvent.RESULT, res);
                    getFavsArraySql.addEventListener(SQLErrorEvent.ERROR, error);

                    getFavsArraySql.text = "SELECT * FROM favGames";
                    getFavsArraySql.execute();

                    var favsArr:Array = new Array();

                    function res(e:SQLEvent):void
                    {
                        trace("sql good!");
                        favsArr=getFavsArraySql.getResult().data;
                    }

                    function error(e:SQLEvent):void
                    {
                        trace("sql error!");

                    }

                    trace(favsArr);

                    return favsArr;
                }

Answer 1

Assuming I understood your question, Instead of expecting getFavsGamesArray() to actually return the results from an asynchronous event (which it likely never will), consider passing a function (as an argument) to call within your res() function that would then process the data.

In your SQL helper class, we’ll call it SQLHelper.as:

private var processResultsFun:Function;

public function getFavsGamesArray(callBackFun:Function):void
{ 
    processResultsFun = callBackFun;
    ...

} //Do not return array, instead leave it void

function res(e:SQLEvent):void
{
    trace("sql good!");
    if(processResultsFun != null) 
    {
        processResultsFun(getFavsArraySql.getResult().data);

    }
}

In the class(es) that call your SQL helper class:

function processRows(results:Array):void {
    //Make sure this function has an Array argument
    //By the time this is called you should have some results
}
...

SQLHelper.getFavsGamesArray(processRows);

You can optionally pass an error handling function as well.
