Retrieve from sql data, adobe air - actionscript-3

Question

I'm trying to retrieve data from a list I was able to create using SqlConnection.
I understand how to repopulate my text boxes by selecting an item from the list box (component). But how would I get data by using a separate button, or timeline event, and fill out the text boxes. t_fname t_lname t_phone
var connection:SQLConnection;
openDatabase();
t_phone.restrict = "0-9";
function openDatabase():void
{
var dbFile:File = File.applicationStorageDirectory.resolvePath("database.db");
connection = new SQLConnection();
connection.addEventListener(SQLEvent.OPEN, onOpen);
connection.openAsync(dbFile, SQLMode.CREATE);
}
function onOpen(SQLEvent):void
{
var stat:SQLStatement = new SQLStatement();
stat.sqlConnection = connection;
stat.text = "CREATE TABLE IF NOT EXISTS contacts (id INTEGER PRIMARY KEY AUTOINCREMENT, fname TEXT, lname TEXT, phone INTEGER)";
stat.execute(-1, new Responder(selectItems));
}
function selectItems(SQLEvent):void
{
b_save.enabled = false;
b_delete.enabled = false;
var stat:SQLStatement = new SQLStatement();
stat.sqlConnection = connection;
stat.text = "SELECT id, fname, lname, phone FROM contacts ORDER BY id";
stat.execute(-1, new Responder(onSelected));
}
function onSelected(evt:SQLResult):void
{
if (evt.data != null)
{
itemList.dataProvider = new DataProvider();
for (var i:int=0; i<evt.data.length; i++)
{
itemList.addItem({label:(evt.data[i].fname + " " + evt.data[i].lname), data:evt.data[i]});
}
}
}
b_new.addEventListener(MouseEvent.CLICK, createNew);
function createNew(MouseEvent):void
{
var stat:SQLStatement = new SQLStatement();
stat.sqlConnection = connection;
stat.text = "INSERT INTO contacts (fname, lname, phone) VALUES (#fname, #lname, #phone)";
stat.parameters["#fname"] = t_fname.text;
stat.parameters["#lname"] = t_lname.text;
stat.parameters["#phone"] = t_phone.text;
stat.execute(-1, new Responder(selectItems));
t_fname.text = t_lname.text = t_phone.text = "";
}
itemList.addEventListener(Event.CHANGE, onChange);
function onChange(evt:Event):void
{
b_save.enabled = true;
b_delete.enabled = true;
t_fname.text = evt.target.selectedItem.data.fname;
t_lname.text = evt.target.selectedItem.data.lname;
t_phone.text = evt.target.selectedItem.data.phone;
}
b_save.addEventListener(MouseEvent.CLICK, saveThis);
function saveThis(MouseEvent):void
{
var stat:SQLStatement = new SQLStatement();
stat.sqlConnection = connection;
stat.text = "UPDATE contacts SET fname=#fname, lname=#lname, phone=#phone WHERE id=" + itemList.selectedItem.data.id;
stat.parameters["#fname"] = t_fname.text;
stat.parameters["#lname"] = t_lname.text;
stat.parameters["#phone"] = t_phone.text;
stat.execute(-1, new Responder(selectItems));
t_fname.text = t_lname.text = t_phone.text = "";
}
b_delete.addEventListener(MouseEvent.CLICK, deleteThis);
function deleteThis(MouseEvent):void
{
var stat:SQLStatement = new SQLStatement();
stat.sqlConnection = connection;
stat.text = "DELETE FROM contacts WHERE id=" + itemList.selectedItem.data.id;
stat.execute(-1, new Responder(selectItems));
t_fname.text = t_lname.text = t_phone.text = "";
}
//// ?how would I do it for this recall button ?
b_recall.addEventListener(MouseEvent.CLICK, recall1);
function recall1(MouseEvent):void
{
t_fname.text = data from the first entry
t_lname.text = data from the first entry
t_phone.text = data from the first entry
}

You have to store the data. It's harder to learn to work around not storing the data. Here's the basic code to add to your code. First line is your existing code, add new below it.
t_phone.restrict = "0-9";
var aItems:Array;
var oItem:Object;
var i:uint;
The first line is another line of your code, add the code below it - sorry that wasn't clear:
itemList.addItem({label:(evt.data[i].fname + " " + evt.data[i].lname), data:evt.data[i]});
// add item to end of aItems array
oItem = new Object();
oItem.t_id = evt.data[i].itemID;
oItem.t_fname = evt.data[i].fname;
oItem.t_fname = evt.data[i].lname;
oItem.t_phone = evt.data[i].phone;
aItems.push(oItem);
Then you can loop through your array and look for matching id or whatever.
// loop through aItems to find match for t_id
for (var i:int = 0; i < aItems.length; i++) {
if(aItems[i].t_id == testID){
trace("f_name: " + aItems[i].t_fname);
}
}
