不允许执行javascript SQLite SQL

我使用下面的代码来显示表单

    notesdb.transaction(function(t) {
    t.executeSql('SELECT buildingcode, buildingaddress FROM buildings WHERE buildingcode = ?', [BuildingCode], 
            function(t, result) {
                var rowaddress = result.rows.item(0);
                $('#displayflatcomments articleflatcomment').html('Κωδικός: <strong>' + rowaddress.buildingcode + '</strong>');
                $('#displayflatcomments articleflatcomment1').html('Διευθυνση: <strong>' + rowaddress.buildingaddress + '</strong>');
    });

    t.executeSql('SELECT id, BuildingCode, FlatNo, Comment, CommentMore, Closed, New FROM flatcomments WHERE New = 1 ORDER BY BuildingCode ASC', [], 
            function(t, result) {
                var rowcomment = result.rows.item(0);
                //alert(rowcomment.id);
                $('#displayflatcomments articleflatcomment2').html('Ονομα: <strong>' + rowcomment.Comment + '</strong>');
                $('#flatcommentdisplay').val(rowcomment.CommentMore.slice(0, rowcomment.CommentMore.length-16));



        $('#paycommentsdelete').click(function(){
            t.executeSql('DELETE FROM flatcomments WHERE id = ?', [rowcomment.id]); 
            $.mobile.changePage('#comments', 'slideup', false, true);
        });    
        $('#sub').unbind('click').click(function(){

        });
    });

});

我有一个带有paycomentsdelete id的删除按钮

单击它时，我收到未捕获的InvalidError:无法对“SQLTransaction”执行“executeSql”：不允许执行SQL

如何修复它？？？

关于这一点的一个想法是，SQLite数据库文件必须是可由服务器写入的。CHMOD777。默认情况下，您可以从数据库中读取，但不能删除或修改

检查数据库文件的写入权限，并确保已启用“可写入”。希望能奏效
