At the moment this is how i'm working this :
// first we need to set the file class for our database (ICM.db).
var db:File = new File ("C:/ICM.db");
// after we set the database file we need to open it with our SQLConnection.
SQLc.openAsync(db); <-- using openAsync()
// EventListener on open
SQLc.addEventListener(SQLEvent.OPEN, db_opened);
// EventListener on result
SQLCust.addEventListener(SQLEvent.RESULT, custResult);
//does the following
private function db_opened(e:SQLEvent):void
{
// when the database is opened we need to link the SQLStatement(s) to
our
SQLConnection, so that the SQL-statement(s) target the right database.
// if we don't set this connection we'll get an error when we execute
SQL
statement.
SQLCust.sqlConnection = SQLc;
//would it be 'bad' if i had a second SQLStatement from the same
connection here ?
SQLVend.sqlConnection = SQLc;
refreshSQLCust();
}
// function to call when we want to refresh the data in datagrid
private function refreshSQLCust(e:TimerEvent = null):void
{
// timer object which we need if SQL-statement is still executing so
that
we can try again after 10 milliseconds.
var timer:Timer = new Timer(10,1);
timer.addEventListener(TimerEvent.TIMER, refreshSQLCust);
if ( !SQLCust.executing )// we need to check if our SQL-statement is
still
executing our last SQL-command. If so we use Timer to try again in 10
milliseconds. If we wouldn't check we could get an error because the
SQL-statement can't execute two statements at the same time.
{
// SQL-statement which returns all the data from our CustTable.
SQLCust.text = "SELECT * FROM CustComTable"
SQLCust.execute();
}
else
{
timer.start();
}
}
private function custResult(e:SQLEvent):void
{
// with SQLs.getResult().data we get the array of objects for each row
out
of our database
var data:Array = SQLCust.getResult().data;
// we pass the array of objects to our data provider to fill the
datagrid
CustDp = new ArrayCollection(data);
}
