I thought I might try my hand at making a customized report generation utility, so I looked into the MyLog.db3 file and am confused. It doesn't seem to have all the data for all the flights I've collected. Something simple like
SELECT * from v_Flights where ModeS='ABC123'; (fake code)
returns no rows unless that code has been seen with a non-null Callsign block?
The Reporter seems to get this right; where's the data being stored? :)
