database - local database null result

Question

I am trying to create a local database. I made some inserts, but when I run the code I get the "result = null" error:

var selectStmt:SQLStatement = new SQLStatement();
selectStmt.addEventListener(SQLErrorEvent.ERROR, dbErrorHandler);
selectStmt.sqlConnection = conn;
selectStmt.text = "SELECT * FROM table1";
selectStmt.execute();

var result:SQLResult = selectStmt.getResult();
var numResults:int = result.data.length;

How can I fix this?

Answer 1

SQLStatementは非同期であり、「flash.events.SQLEvent.RESULT」イベントリスナーでのみ「getResult（）」を実行できます。
