Hi Andy
It would appear that you are not aware that the database table are encrypted so you can use them on an SQL editor
Going from your query it would appear that you are looking to use the database as a log of some sort. You can't do that as the tables are separate and you cant combine aircraft data and route data.
However you can use the Mylog to identify the flights operated by particular aircraft, see attached where I have used Mylog to show the flights that I picked up over the last month operated by LN-RGH. Unfortunately you cant do the same in Mylog for a particular flight ID as my log operates on the aircraft table data and it cant for example give you a list of all aircraft which operates a particular flight over a given time period
If this is not sufficient for your needs I can only suggest an Excel type table to uses as a separate database an something like OpenOffice would enable you to start one at no cost
Hope this helps
