Hi guys i'm making a mobile app with flash builder but i stumble upon an error. In short terms, you put a text in a text input, u click a button and it only lists the things from the database with that imputted text in it. Here are the codes:

'

First the Homeview.mxml:

<?xml version="1.0" encoding="utf-8"?>
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009" 
  xmlns:s="library://ns.adobe.com/flex/spark" title="Home"
  xmlns:dao="dao.*">
  <fx:Declarations>
  <dao:RoosterDAO id="srv"/>
  </fx:Declarations>


  <s:Label x="11" y="6" fontSize="36" text="Klas:"/>
  <s:TextInput id="Klas" x="91" y="6" width="262" height="30"/>
  <s:Button id="btn" x="361" y="0" height="40" label="Button" click="data=srv.findByKlas(Klas.text)"/>

  <s:List id="list" top="48" bottom="0" left="0" right="0"
  dataProvider="{data}">
  <s:itemRenderer>
  <fx:Component>
  <s:IconItemRenderer
  label="{data.Klas} - {data.Vak} - {data.Docent}"
  messageField="Positie"/>
  </fx:Component>
  </s:itemRenderer>
  </s:List>


</s:View>




and secondly the sql .as file :
package dao
{
          import flash.data.SQLConnection;
          import flash.data.SQLStatement;
          import flash.filesystem.File;
          import flash.filesystem.FileMode;
          import flash.filesystem.FileStream;
          import mx.collections.ArrayCollection;

          public class RoosterDAO
          {

                              stmt.text = sql;
                              stmt.parameters[0] = id;
                              stmt.execute();
                              var result:Array = stmt.getResult().data;
                              if (result && result.length == 1)
                                        return processRow(result[0]);
                              else
                                        return null;

                    }
                    public function findByKlas(searchKlas:String):ArrayCollection
                    {


                              var sql:String = SELECT * FROM rooster WHERE Klas LIKE ?;
                              var stmt:SQLStatement = new SQLStatement();
                              stmt.sqlConnection = sqlConnection;
                              stmt.text = sql;

                              stmt.execute();
                              var result:Array = stmt.getResult().data;
                              if (result)
                              {
                                        var list:ArrayCollection = new ArrayCollection();
                                        for (var i:int=0; i<result.length; i++)
                                        {
                                                  list.addItem(processRow(result[i])); 
                                        }
                                        return list;
                              }
                              else
                              {
                                        return null;
                              }
                    }


                    protected function processRow(o:Object):Rooster
                    {
                              var rooster:Rooster = new Rooster();
                              rooster.id = o.id;
                              rooster.Klas = o.Klas == null ?  : o.Klas;
                              rooster.Vak = o.Vak == null ?  : o.Vak;
                              rooster.Docent = o.Docent == null ?  : o.Docent;
                              rooster.Lokaal = o.Lokaal == null ?  : o.Lokaal;
                              rooster.Positie = o.Positie == null ?  : o.Positie;

                              rooster.loaded = true;
                              return rooster;
                    }
                    public static var _sqlConnection:SQLConnection;

                    public function get sqlConnection():SQLConnection
                    {
                              if (_sqlConnection) return _sqlConnection;
                              var file:File = File.documentsDirectory.resolvePath(rooster.db);
                              var fileExists:Boolean = file.exists;
                              _sqlConnection = new SQLConnection();
                              _sqlConnection.open(file);
                              if (!fileExists)
                              {
                                        createDatabase();
                                        populateDatabase();
                              }
                              return _sqlConnection;
                    }

                    protected function createDatabase():void
                    {
                              var sql:String = 
                                        CREATE TABLE IF NOT EXISTS rooster ( +
                                        id INTEGER PRIMARY KEY AUTOINCREMENT,  +
                                        Klas VARCHAR(50),  +

                              var stmt:SQLStatement = new SQLStatement();
                              stmt.sqlConnection = sqlConnection;
                              stmt.text = sql;
                              stmt.execute(); 
                    }

                    protected function populateDatabase():void
                    {
                              var file:File = File.applicationDirectory.resolvePath(assets/rooster.xml);
                              var stream:FileStream = new FileStream();
                              stream.open(file, FileMode.READ);
                              var xml:XML = XML(stream.readUTFBytes(stream.bytesAvailable));
                              stream.close();
                              var RoosterDAO:RoosterDAO = new RoosterDAO();
                              for each (var emp:XML in xml.Rooster)
                              {
                                        var rooster:Rooster = new Rooster();
                                        rooster.id = emp.id;
                                        rooster.Klas = emp.Klas;
                                        rooster.Vak = emp.Vak;
                                        rooster.Docent = emp.Docent;
                                        rooster.Lokaal = emp.Lokaal;
                                        rooster.Positie = emp.Positie;
                                        rooster.Type = emp.Type;


                              }
                    }





          }
}






The error is at the findByKlas function and it goes like this:

SQLError: 'Error #3115: SQL Error.', details:'no such table: 'rooster'', operation:'execute', detailID:'2013'
          at flash.data::SQLStatement/internalExecute()
          at flash.data::SQLStatement/execute()
          at dao::RoosterDAO/findByKlas()[C:\Users\Thomas\Adobe Flash Builder 4.6\ARHC test\src\dao\RoosterDAO.as:36]
