Simple answer - I don't - but when I add the new data it is all clumped at the bottom of the list in the Stations search window. As per comment from coderus, I have read the documentation for sqlite3, there isn't much to read, the commands seem quite simple, but I've ended up with the same result as last time - the new stations are NOT listed alphabetically and are at the end of the list and so, when the app is used, the user is presented initially with all stations listed in alphabetical order, that is until the user scrolls to the bottom and finds a handful of stations in no particular order at all.
