Failed to retrieve data from SQLite to Air application.

Use a simple database and get an error: selectError SQLError: 'Error #3115: SQL Error.', details:'no such table: 'nnn'', operation:'execute', detailID:'2013'

But the table 'nnn' in the database is available. I tried several different files, create new database - no result. Code to query the database:

import flash.data.SQLConnection;
            import flash.data.SQLStatement;
            import flash.data.SQLResult;  
            import flash.data.SQLMode;  
            import flash.events.SQLErrorEvent;  
            import flash.events.SQLEvent;     
            import flash.filesystem.File;    

            private var conn:SQLConnection;
            private var createStmt:SQLStatement;
            private var insertStmt:SQLStatement;
            private var insertStmt2:SQLStatement;
            private var selectStmt:SQLStatement;



            protected function init(event:FlexEvent😞void
            {

                var dbFile:File = File.applicationStorageDirectory.resolvePath("ttt.db");

                conn = new SQLConnection();
                conn.openAsync(dbFile);
                conn.addEventListener(SQLEvent.OPEN, openSuccess);
                conn.addEventListener(SQLErrorEvent.ERROR, openFailure);
            }


            protected function openSuccess(event:SQLEvent😞void
            {
                conn.removeEventListener(SQLEvent.OPEN, openSuccess);
                conn.removeEventListener(SQLErrorEvent.ERROR, openFailure);
