Sqlite, moving sqlstatements to a custom class

Question

I'm working on a FB AIR app.
I have a main.mxml file with a source to a main.as file.
My main.as file is getting very bloated with sqlstatements. I want to move these to a custom class, but I don't know how to proceed.
I found an example of a package on this page: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/data/SQLConnectio n.html#begin()
about a 3rd of the way down.
The example above is exactly what I want to do, but I don't know how to adapt this for use in my main.as file beyond importing the class and instantiating it. How do I assign my values to the class file? How do I use the class to load up the dataProvider, etc...
Also, in the example above the class extends Sprite. This sounds like it's meant for a Flash application. Would I still extend Sprite in Flex 4? I have done a couple of simple events, passing data back to the main app with the Flash.Events.Event, so the use of Sprite causes some confusion.
In a previous post, Amy suggested using Robotlegs. I think I need to get a handle on using Flex before I explore other architectures. I'm just not that sophisticated yet.
Thanks

Answer 1

ok, a quick example
make a new package called utilities and then a new actionscript class called DatabaseManager
package utilities
     import flash.data.SQLConnection;
     import flash.data.SQLResult;
     import flash.data.SQLStatement;
     import flash.filesystem.File;
     import mx.collections.ArrayCollection;
     public class DatabaseManager
          private var sqlConnection:SQLConnection;
          private var stm:SQLStatement;
          public function DatabaseManager()
               //connect to database
               sqlConnection = new SQLConnection();
               sqlConnection.open(File.applicationStorageDirectory.resolvePath("whatever"));
               //create tables if not exist
               stm = new SQLStatement();
               stm.sqlConnection = sqlConnection;
               stm.text = "create your table here";
               stm.execute();
               //create more tables
          public function getThings():ArrayCollection
               stm = new SQLStatement();
               stm.sqlConnection = sqlConnection;
               stm.text = "your query";
          public function addStuff(stuff:Object):int
then in your main file you need to import
import utilities.DatabaseManager;
instantiate the class, this connects and creates tables
private var myDB:DatabaseManager = new DatabaseManager();
then to use it
var listFromDatabase:ArrayCollection = myDB.getThings();
insertid = myDB.addStuff(thingToAdd);
hope that gives you an idea
